The ultimate DIY? A Stax SRM-T2!

Beautifully neat looking work Craig, re-spect. How long did it take you?

Thanks struts and voltron.

I didn't keep a tally, but I guess it must have been ten hours for both boards, or maybe a little more, spread over three days. I don't have a flip over frame to help soldering, so I stuck a piece of carpet onto piece of plywood just larger than the big board with carpet spray glue. Used a lead bender to assist component preparation while the boards were propped on two transformers - then put the carpet gizmo on top and flipped it. Worked a treat.

The delrin extension is what i had in stock. Aluminum works fine.

The knob gets as hot as the rest of it. Its unlikely that people are going to listen to this

thing 12 hours a day, and the anodizing is going to definitely get rid of the heat.

On the original, the knob got very hot too.

The 2sc3381's i have measure a diameter of .020

and i reamed the holes out to .0205

will go find some 2sj109's to measure.

I'm assuming that's the "major diameter"? I thought they had square pins...

The pins are square. I got .020 on the flats and between .0235 and .0240 from corner to corner. Regardless, they still fit(on my board anyway), all be it very very snug.

I don't see any problem reaming the holes out, if needed, as long as one makes sure to properly solder both sides of each lead(both sides of the board.)
