Ok, was suspect because it was attached to C11, turns out that was the only thing I put in backwards. All diodes and resistors in/around the bias circuit test ok. The bias is still 14mv and the pot does nothing (it tests ok) I measured at the speaker terminals, 0mv at the left channel, 56mv on...

I'm gonna check the MPSA92 (Q1) that was near C11. The OPA134(U1) is suspect too. Should I totally unhook the left side of the board if I sub in U1 off the left side?

Changed out cap (Panasonic?) and we still have bias stuck under 14mv on the right side, so something else blew. Bias adjusts fine on the left side +-15v rails are present, no blown fuses. not sure what I smoked. I checked to see if anything else was backwards, Replacement 220uf/25v capacitor...

Shameful display.....

Welp, First gaff. Bringing up on the variac/DBT, have first row installed, control board, setting bias. C11R on the control board was installed backwards, started to bulge up and make Q50R/Q51R hot. No wonder the bias won't go above 14 mv on the right. Gonna let it cool off and see if I have...

Huh, I've only had em buzz if the capacitors were rotten (or lifted ground)

I think epay or AliExpress. I may have got mine at LP Gear and paid 20 whole dollars for it, I figured if Rega was putting their name on them and selling them for $70 they can't be that bad...

That's why I'm sticking with that $12 AT3600 for now. It also happens to have a .06 mil conical tip.....

It's strange that the SMPS doesn't detect the input voltage. Easy fix anyways

Yeah Ive gotta run for zip ties in the morning. Did more wiring and mocking up to check that everything fits. We're getting close.....

Looks more daunting than that Sony 3 header I have in the back room. Are you looking to hear some old tapes you have or make mix tapes?

Progress report! Been fitting, wiring.....

Yep I'm always down for picking up swing and country (and country swing) on shellac. I think I have 30 or so 78s. But I only get em local and cheap cuz they break......

Yeah I don't eat Taco Bell much anymore. They're service was terrible during covid and they discontinued all my favorite stuff. Add me not drinking soda anymore (including Baja Blast, which I miss) and the prices getting outrageous. Final nail.......

Yep they solder

They just push in and the 6-32 Allen head bolts hold em down

Yeah I'm deep into a WOPL conversion on a 700B, I think I have about 1k in it but I did buy a new chassis/DC protect/triac switch. Also have a variac, dim bulb tester, and good soldering irons ready. I'm using 3 irons, a Rat Shack 40 watt, a Weller 60 watt, and a Weller Expert 100/140

Okay stupid question time, I ordered Switchcraft 3501FRX RCA jacks and they don't fit. What fits?
