Almost there. Just the grid caps to wire before I plug in and test.
Took some trial and error to sort the input - grid caps and thin screened wires are a pain. This is where I am up to:
Decided to connect 0V signal to chassis near the RCA. Also grounded the grid wire screen at the same point. The two binding post thingies you can see (green wire attached) are not speaker outputs - they are banana test points for measuring 6C6 cathode current (voltage dropped across a 10 Ohm R) externally so I can set 6C6 plate and output grid voltages.
Connector mounting plates all installed:
The mounting plates are inset to provide protection for switches, fuse holders, and connectors. You can see the banana test points next to the RCA - multimeter pugs in there.
Should be able to sort the grid caps tomorrow and maybe even fire up for a smoke test and see where (if!) the voltages settle. I'm a little apprehensive - tried quite a few new techniques in this build and really not sure if it will work.
Oh, and they weight a heap - about 20kg per channel is my guess... 10kg per Watt. Daft. Looking forward to a simpler next build - maybe EML 20B/M drives PP 45?
Cheers.
