Thanks, it (the schematic) opened in a new window fine!

Hope I may add some suggestions here.

If the lead spacing of C1 allows for 27.5 mm (to me it seems to) you should consider
this film-foil type instead of the cheaper metallized poly, also available at Mouser:

Mouser 505-FKP41.0/400/10

For C6 & C7 you might consider these (same 5 mm lead spacing as Wima MKP):

Mouser 505-FKP2.022/100/5
Mouser 505-FKP20.033/63/2.5

Where a wider lead spacing is applicable FKP3 is an even better choice.

For C5 I need to say, that at least many using the PCBs of an earlier German group buy
had much better results with 10 pF - both audibly and measured. I have to admit this
might differ depending on the PCB design.

Added chassis assembly section.

Jim.....as normal, your photography is outstanding, as are your assembly guides!

I am still waiting for my boards and you guys are all having fun. My boards apparently left the US at Los Angeles on the 21st of August and I still don't have them. Damn, sometimes staying in dark corners of the world bites.

Must .. be .. patient.

Whetted my FirstWatt appetite with the ACA. Such good sound from the simple amp.

Pawing through my left over boxes yielded a quad of Silmic II 220 mF 100v caps. They look to fit well on the board. I also found 4 nice 1 uF film caps from a pair of speaker crossovers that were upgraded. They are about 1 inch long, 1/4 inch diameter. Will they be better or worse bypass caps with the longer leads that will be needed to hook it up? It would be silly to use them, and have them be markedly worse due to longer connections. Actually, I'll put those at C1, and stick with the Wima bypass caps.

Got my boards and 500u case. AnTek Transformer was shipped this week. JFets are here, output transistors from Buzzforb en route. Finish up my Mouser BOM, and I'll be cooking.
