NCC200 V1.4/Cap6 GB

shoom

open ears and mind
Hi All.

Following on from the many good build threads here and happy owners I though it may be time to ‘’share the love’’ a little further. I’ve been using the new NCC200 V1.4 boards for a while now and they are IMHO a step up from the v1.3. The new V1.4 boards also benefit from some layout tweaks and also from improved ventilation of the driver transistor heat sinks which can only be a good thing.

Les has indicated that a GB may be possible if enough boards are required.

NCC200 Boards and parts kits.

Options.

1) 2 x NCC200 board and small driver heat sinks. Connector blades, custom wound inductors for the OP Zobel. 100uf Mil wet tant for FB duties.

2) 2x NCC200 V1.4 boards only.

3) 2x Large U shaped heat sinks with fixing kits for the OP transistors.

4) Cap6 Boards.

Cap6, will be boards only.

So all of the boards and some of the harder to find parts needed to build lovely NCC200 amp/s.

I’ll be publishing the circuit diagram and boom (pretty much the same as the V1.3 but with two component value changes) and also the build guide if that’s OK with Les.


Now we get into the GB proper.

First stage collecting address details. Anyone with A next to their name means address received.

Hi All

I’m now in possession of firm prices which are as follows:

(UK Pounds)

1) NCC200 PCB with FB Tant, Zobel Coil with resistor, Driver heatsinks and connection tabs - £20.00 per board (£40.00 pair)
2) NCC200 Bare PCB only - £11.85 per board (£23.70 pair)

3) Large TO3 heatsink with insulators, mica pads, stainless fixings - £14.25 per sink (£28.50 pair)

4) Cap6 PCB with drilled and black anodised heatsink. insulators and stainless fixings, 4 X stand off feet - £14.85 per board (29.70 pair)

Just a few words on the GB.

Yup I know that I’ve done things a little differently from the norm here but I’d prefer to conduct things pretty much in the same way as the VBE GB.

I’ll be doing most of my communication through PM so please make sure that you check yours regularly.

First stage postal details.

I tend not to keep peoples postal details on my computer and prefer to store them as a word document on a flash drive which I keep locked away.

So people from the VBE GB will need to re supply their details.

It would greatly help the process this end if when asked to provide postal details in the following format.

PFM name

Real Name

Full postal address including post/zip code and country

Postage requirements.

Please consider the value of your order and request the postal service that you feel happiest with. I used Royal Mail for the last GB and had 100% delivery so I’ll be doing the same again.

Please note that once posted my responsibility ends so choose wisely.

Anyone not providing their postage requirement will ship first class recorded delivery.

I’m intending to start collecting postal details within the next few days.

BTW anyone who feels the need to drop out for whatever reason please let me know when I ask for your address details.

The NCC200 are great amps with a nice upgrade path and way better than it’s some of parts IMHO.

I hope you all have as much fun building them as I did.
 
NCC200 Schematic

After starting to compile a parts list I noticed a few more component changes from the original circuit which I’ve now added.

Hi All

I’ve compiled the following Suggested parts list which is pretty much what I’ve used for my NCC200 V1.3 build.This list is designed as a point of discussion and my change so not the finished item. It’s not intended to be prescriptive but to give the less experienced a viable start to their adventure.

Some experienced eyes on this would be appreciated. Have I missed something? Are the suggested parts ok?

Some opinions would be appreciated.

Graham has kindly posted a Google Doc spreadsheet with all info relating to the parts required for a successful build.

http://api.viglink.com/api/click?fo...docs.google.com/spreadsheets...it?usp=sharing

What a guy.

Thanks for stepping up to the plate Graham. It’s really nice to see an up to date build list.

Great work that will be much appreciated.


Should work out much the same but with 2 revisions which I’ve included.
I’ve listed the Farnell part numbers just as a reference so people know what’s required but feel free to choose your own parts as this is DIY.

For two boards

Capacitors (FarnellNo)

C1, 5 100uf 63V Panasonic FC Series x 4 (9692517)

C3 10uf x 2
This is the IP cap and is IMHO a personal preference so let’s discuss this part and make your own choice based on that.

C2, 4, 12 100nf Wima x 6 (1006030)
Some of us have had fun using polypropylene in this spot.

C6 100uf 10V Tant or film depending on taste. x 2
Feedback cap will be provided with the minikit.

C7 220pf 500V Silver Mica x 2 (1264884)
Others have used polystyrenes in this spot but close tolerance and good HF performance are key here.

C8 47pf 500V Silver Mica x 2 (1264876)

C9, 10 470pf 500V Silver Mica x 4 (1264889)
Others have used polystyrenes in this spot but close tolerance and good HF performance are key here

C11 68uf 6.3V BC128 x2 (1166615)

C14 330pf 500V Silver Mica X 2 (1264887)
Others have used polystyrenes in this spot but close tolerance and good HF performance are key here

TR4) ZTX753 x 2 (9525637)
TR5) 2N5551 X 2 (9846751)
TR6) ZTX653 x 2 (9525580)
TR7) MJE15030 x 2 (9557091)
TR8) MJE15031 x 2 )9557105)
TR9, 10) MJ15003 or BUV20 can be used x 4 (1165909)

The ONsemi version of the MJ15003 is said to be superior so maybe for the little extra cost worth thinking on. I use buv20 which I like but they are pretty expensive.

any cock ups or omissions? let me know.:cool:


This parts list based on Misterc6 (Malcolm) superb parts spread sheet.
Thanks Malcolm.
 
Build Notes

I’ll be adding to these over the next week or so. If I miss something please shout out as it’s easily done. Let’s also keep in mind that we have builders at all levels so what may be easy for some will be a little harder for others.

Any tips from those who have built NCC200/Voyagers before most welcome.

The first thing to note is that TR1 needs to be +10% higher HFE than TR2 which ensures the correct DC offset at the OP.

The Transistor tester on most digital multimeters should be fine for this or the Atlas DCa55 which I use and is superb for such things.

http://www.amazon.co.uk/dp/B004Y0HV72/?tag=pinkfishmedia-21

I’ll have a look through my transistor stash to see what I have but most of my gear is packed away pending the move to my new workshop. So I’m hoping that some of the more experienced builders here will help out the less experienced with some transistors should the need arise.

Also some useful Build threads that may help some:

plenty of picture in these. Thanks Mark, Keith, Alan and the poor quality offering bringing up the rear.:D

Stunt Speakers.

My most valued speakers are without doubt the stunts which are a must IMHO for ant DIY amp build.

Almost any cheap and cheerful speakers are perfect and can be had from most good boot sales or charity shops. They are really good to test your newly built amplifier under load conditions after performing all of the preliminary tests and bias setting before commiting to the main rig. I usually keep the stunt speakers in for a few days just to make sure that all is well.

The stunts are well worth the small investment required.

if you've got them, use them:D

Fancy Dan

He can walk the walk but can he dance the dance?:D

A few words to the less experienced builders.

My builds always start off by using pretty standard parts and I try to avoid the fancy Dan components until after my work has proved itself over time.

Nothing worse than seeing those nice expensive caps in a swirl of magic smoke IMHO.

Building with standard parts gives the chance to experiment later so a little more learning later.

My first NCC200/Voyager build was made with the components listed in the parts list with just a few alterations and sounded superb.


more to follow:D

Maybe this would be better off waiting until Les has released his ncc300 board which sounds like it will be more akin to our own hakernap?

Sorry to bear sad tidings:

For the time being, I won't be offering the NCC300 for general DIY as
I have in mind to launch an upmarket amp using the miles of custom
extrusion I've had for some time.

Hi Stephan.

Good point.:cool:

But no reason not to consider a GB for those at a later stage if people want them and Les is willing.

Of course there are clear advantages in building the NCC300 (looks lovely) in terms of having the whole thing at once but that may not suite everyone. Especially if things go a little wrong.

The NCC200 does have some advantages for the Joe average DIYer (like myself) over the 300 though IMHO. The biggest on being the ability to build and test in stages.

NCC200 first and then add the VBE for the Voyager sound later. Not so important for the seasoned builder but pretty useful for the less experienced to gain a little know how and confidence.

IMHO it’s nice especially for builders to start with a very good amp and have an upgrade path later if they choose it.

So it’s KISS all the way

No Worries:cool:
 
Do the Cap6 boards take the three legged Schottky diodes?

MBR20200 dual Schottky I think (from my own posting in the VBE build thread).
Les mounts them on a single aluminium bar heat-sink. They will need mica washers + tape or something to stop the heat-sink shorting on tracks underneath.

Cheers,
Barry.
 
Oh balls, still haven't got round to starting building from the last GB. I think I'd be in for

1 set of ncc boards with all the trimmings
4 cap6 boards.
 
Hi Shaun, and happy new year.

Thanks for doing yet another (possible) group buy.

I will express an interest in enough parts for another 4 mono amps. I already have enough VBEs from the last GB and some MiniCaps.

2 x Option 1) (pair of NCC200 + some parts)
2 x option 3) (pair of Heat-sinks)
4 x Cap6 Boards

Must get around to finishing my first 2 Voyagers which I have (almost) all the parts for :)

Cheers,
Barry.
 
How exactly do these 1.4 boards differ from the earlier boards? Are there any actual circuit changes or is it just a layout change? Is Les able to offer minicaps for the front end as the Cap6 boards are quite big or are we just talking basic NCC200 here?
Do we have any idea of cost before I commit myself?
 
Hi Guys

Nice to have your company again.:cool:

So just by way of explanation.

All expressions of interest will be listed in post one and the numbers refer to the number of boards required.

So for example one pair of NCC boards are listed as 2 x and two pairs 4 x and so forth.


Hope that's clear
 
‘’How exactly do these 1.4 boards differ from the earlier boards? Are there any actual circuit changes or is it just a layout change?’’

No real circuit changes but better construction and optimised component layout.

Does it make a difference?

IMHO yes but you may think otherwise which is:cool:

‘’Is Les able to offer minicaps for the front end as the Cap6 boards are quite big or are we just talking basic NCC200 here?’’

Just parts for the NCC200 ATM but Les may be willing to supply you with Minicap6 directly if you require some. I’m happy that I’ll have enough work to do with the GB as is so I’ve tried to keep things manageable.

‘’Do we have any idea of cost before I commit myself?’’

Cost may depend on how many boards and such like.

So

No commitment needed.:cool:

As stated in my first post I’m just trying to gain some idea of numbers and GB viability.

Feel free to express an interest and later if the price is wrong for you just say so.

No one will be forced to participate but once we get to the ordering stage then anyone on the list that has not said otherwise will be errrr expected to go the whole way.:D

BTW

For our friends over the water.

The last GB shipped to most continents so don’t feel excluded.:cool:

Everyone received their order.
