L-pad instead of H-pad??

"Instead, get a dual gang 5k audio taper pot (i.e. Mouser 313-2420F-5K) and wire it across the transformer secondary"

Could i still just use the dual gang pot across the secondary given your above comments since I already have them, instead of the simple L-pad prior to the output transformer?

Sounds crazy but i am having difficulty finding 8 ohm L-pads, they all seem to be the wall plate -mount type.

Re: Interconnect wire recomendations?

For short runs between XLR input and Input transformer primary and also bewteen Input transformer secondary and plate would you recommend shield twisted pair, twisted pair or shielded single solid conductor wire. The run lengths are only about 3"- 4"

Input transformer? What input transformer? You mean for the microphone input? And when you say between the secondary and plate, do you mean grid?

Anyway, a simple twisted pair should work just fine.

Well, since we now know that your mic preamp is ultimately a power amp and is designed for driving an 8 ohm load, I'd stick with the 8 ohm L pad.

Most of the wall plate types I've seen were just a basic L-pad mounted to a wall plate. Should be able to just remove the knob, undo the bushing nut on the L-pad and remove it from the wall plate.
