HaHa I wish, it does sound excellent though thanks Gerviais CoteAre you an employee of Nagra Audio or Dan D’Agostino ???
If it sounds as good as it looks, this will be awesome !
Si, you're addicted, admit it.
That's kinda neat.
OK, it's not quite on a par with you guys crafting your own speakers, but it kept me busy for an afternoon
Pi model B (the very first one), HifiBerry amp off ebay, an old laptop power adaptor, a few connectors. Less than £15 all-in! Powering some Mission 760i speakers it sounds not half bad.
Don't worry, they'll have the lids on.Very nice builds Booja!
The casework is very professional indeed.
(But please insulate/cover up the live mains terminals before you sell them ).
I finally wrapped up my Pass/FirstWatt F5 25w class A amp and BA2018 preamp (designed by Wayne Coburn from Pass Labs).
They sound excellent, and I'm very happy with the way they turned out (aesthetically, build quality, etc.). I learned a lot of CAD skills along the way (faceplate and internal custom parts). Nothing smoked or blew up, and I never shocked myself. The preamp is very quiet, and the only noise from the amp is a little hum from the big 500VA transformer (hum from the transformer itself, not the speakers). The preamp is dual mono with one VRDN PSU/transformer per channel. The amp includes soft start and speaker protection boards.
The BA2018 preamp:
And the F5:
And the happy couple together:
After all that hard work, I am going to sell them! I've never owned anything class A before and didn't appreciate until it was finished how much heat it produces. I live in Valencia, and even now that it's in the 70's and 80's out, it gets uncomfortable in our apartment with the amp running. The beast belongs up in the north somewhere where it will serve a dual purpose (space heater and music maker).
Really neat build...I always have that intention to get my builds that neat, but I never pull it off like you have.I finally wrapped up my Pass/FirstWatt F5 25w class A amp and BA2018 preamp (designed by Wayne Coburn from Pass Labs).

Good question!Really neat build...I always have that intention to get my builds that neat, but I never pull it off like you have.
Quick question about that switch in the front panel, it has 240V AC through it? Certainly on the preamp, but on the F5 I assume there's a like buffer board for the power, too much current and all that?
Happy to oblige...I am highly disappointed with the professionalism of build, both in looks, and in implementation. You should all be ashamed, I mean where is the huge rats nest of wiring, a much too small enclosure with all the bits and bobs hopelessly crammed in, just waiting for a house fire to occur?
Well done all, I love looking at the nice builds, congrats!
Don't worry, they'll have the lids on.
But seriously, I've worked on several commercial amps/preamps/PSUs (Naim, Quad, Rega, Sansui, NAD) that have exposed mains inside. Joe Henry's Pass clones on eBay have unprotected terminals, fuse holders, tab strips inside. I'd understand if it was an unsupported piece of bare metal that could flex and touch something else... But I would have thought it was pretty clear that there aren't user serviceable parts inside and once the cover is off you're taking a risk.
I'm curious to hear your thoughts (and others).
