I would change C2 to a Nichicon ES Bipolar, not the lowest ESR but very low leakage and distortion Alan

For info, Just had a mail from LesW and he says he uses Safewash Super followed by a warm water rinse https://cpc.farnell.com/electrolube/swas05l/flux-cleaner-safewash-super-swas/dp/SA02329?st=electrolube Alan

OK thanks for all of your responses👍 Looks like I just need to repeat the process a couple of times with the IPA Think I will try a final flush with warm water as well I also have a big bottle of record cleaner which could be good for the final rinse as its just IPA distilled water and a...

What are you guys using for flux removal from a PCB Ive got most of it off with IPA and a stiff plastic brush, but it still feels a bit tacky Anyone tried detergent and water?, no capacitors fitted at present only resistors diodes and transistors Alan

I normally use a Metcal MFR1350 with switchable solder sucker and soldering on the other outlet, unfortunately its stopped working so I am using a Pace sensatemp soldering iron which is a nice unit and a cheap Chinese solder sucker Ive had a look at the Metcal and the power supply is ok but it...

Sound awesome Mike :cool:

Yes , I don't like standing on cold hard floors. I laid a 5" slab of concrete for the founds but I have covered that with 25mm kingspan type insulating board and 18mm flooring so at least its a warm floor. Maybe some type of neoprene floor tiles ?. Im going to build a smaller desk on the other...

Mike It depends if your friend has a pre amp with balanced outputs ? and how & where is the signal ground is connected to chassis ground in his system? RANE do some good papers on various scenario's https://www.ranecommercial.com/kb_article.php?article=2107...

According to Jeff Spall it reduces mass, resonance and standing waves. Here is a link to the audiomods web site, lots of good info in Jeffs downloads/ manuals, http://www.audiomods.co.uk/ http://www.audiomods.co.uk/downloads/armbuild.pdf Alan

If I remember correctly when I built my audiomods arm I just used a 320 grit flapper wheel and then a polishing mop with a range of fine abrasive paste. As stock the RB250 are a bit rough . by Alan Towell, on Flickr Audiomods rega kit 10 by Alan Towell, on Flickr LP12 by Alan Towell, on...

It seems that you made quite a lot of changes as the same time as the rectifiers so how can you be sure that the changes you hear are related to the rectifiers only ? One step at a time is the best way to judge in my experience Alan

I would only use a 00 wire wool as it will remove the Lacquer and get into the grain without removing the veneer If you wish to re veneer, it isn't difficult and I personally like a walnut finish I managed to re veneer this turntable plinth and I am no expert with wood Garrard 401 plinth by...

It is, correct Alan

This is the wiring diag for the NCC-200 but the NCC-220 is a similar pin out so check your wiring is correct. I have always wired the neg speaker terminal back to the dirty 0 Volt end of the minicap 6 as per this diag Disconnect your signal and ground for testing Check the DC offset across the...
