LA2A p2p - 220AC wiring

[hugo]

Hi, i buold an la-2a with hammond 369jx.. since i always use 2x115v trafos, it is new for me to have so many wires...
I made a little draw, could you please tell me what i am supposed to do with "?" and if the rest of wiring is right..?
thank you

i Would suggest rainton's (martin's) Facebook group. there is a diagram showing the exact connections. I would not cut the wires you don't need. just put some insulation around each wire and fix them somewhere in the corner of Your case. maybe you need them in the future...

yes, i know that group, but it is far less reactive than groupdiy forum ^^

There already is a post with an answer to your question. Just scroll down a bit. Or look in the image section. There is an image from the layout on which Martin posted the exact wiring.

Use the 120V taps. Shrink-tube the 100V and 110V leads and wire-tie them in a loop, just-in-case this is ever used in Japan or some place on the low side of 220V.

The 50V tap is for bias on a power amplifier. The LA2 does not use it. Again, insulate and tuck away.

The Ground on the IEC Inlet should go *direct* to case. The CT on the high voltage should go to the first filter cap, *then* to an audio ground on chassis.
