O.K. I have actually wondered if/when you got some time to sleep.

I've checked Mouser's shared BOM and it includes caps (Nichicon FW) for C102/C202 but in this moment they're not available, maybe this is the reason you didn't received them, Bob.

BTW It could be better this way, they're not so good for those positions, final BOM will have different caps (probably FG: 647-UFG1H101MPM)

Cerafines are very good caps for those position.

Thanks, I found some 100uf / 50V from the MyRef 1.3/1.2 builds. I'll add something better to my next order.

Here are the pics of all installed other than Heat Sinks, Relay. LM3886 (I think)

Please review.

At a first glance it seems fine...

I can't read LM337, BC639 and BC640 markings, check them against silk screen (just to be sure ... ).

Just found a mistake

I mounted and trimmed R3 before attaching the heat sink so now the leads are too short. I remember one must do this with the LM3886 chips but I totally forgot it on R3. Luckily I have some double sided CPU heat transfer tape I can use till I get some new parts

The transformer should have double 25V (24V also fine) secondaries, let's say:

Secondary 1: green/yellow
Secondary 2: violet/white

They should be branched that way:

Green to AC1, Yellow to NAC1
Violet to AC2, White to NAC2
Please confirm.
