Thank you so much for the document,
and congrats for your work.

Only if I had the time to be able to build this...

Absolutely beautiful. Well done!
One thing....... And it really doesn't matter. However you went to great lengths to do this.
The BA183/ BA283s that I have encounterd have metal standoffs for the 2N3055 you mentioned Nylon stand offs.
However wouldn't Nylon be "better"???

Hello! Sorry for the late reply

I wasn't sure what they were using in the original Neves but I'm glad to know that now! It shouldn't make a difference as far as I know since the standoff is not touching any trace, just the PCB itself.

Only scenario I could see happening is if an electrolytic capacitor were to leak then it could short on it... So in that case nylon would be better but again if a capacitor leak goes far enough to reach the standoffs it probably shorted somewhere else too lol!

I just jack the heatsink away from the pcb with some M4 nuts since I use M4 nuts and bolts anyway.

Hello all! I was assembling another B283 card and noticed a small mistake in the values written in the guide for R10. It is 68k ohm and not 18k. It is now fixed and the new link is functionnal.

Happy building!

What kind of rotary switch to buy? Are there any parameters? Thank you

I used the ELMA 04-3133 which is a 24 position 3 poles shorting rotary switch. It is kinda costly but it is the exact model they use in the preamp!

Hi..as others have said..it's a wonderful document you have put together and your builds are very inspiring! You mention sourcing the metalwork on ebay and/or someone on the forum? I was thinking that finding empty cases might be the tricikest part? I would really like to find a source...

Sasarist on this forum makes some very nice cases and sometimes the PCB too!
As for ebay I found them with the seller “retroarchive”. They are still being sold. Little pricy but the faceplate is very well made and it comes with the DPDT switch + labeled switch caps!

thanks for the info! I will follow up
