Crate GX-1200 - Problems persist after new parts

[g1]

Dude and G1. Lets do this the diplomatic way.
Do I replace IC3 again ( may have blown it but no supporting evidence). or float the final emitters.

Both of us said to float the emitters, in agreement with your earlier question. It's like you are not reading the posts here.
I assumed you had the emitters floating, had the variac at full line voltage, and have + and - 1.4V at IC3 outputs.
But you do not respond to confirm.
If we do not know the operating conditions it is impossible to advise.

Ok, all 4 emitter resistors are clipped and I can run it up to full AC voltage. The amp is now drawing about 180 mils of AC current idle.
I'll start some DC measurements soon. Gotta entertain some grandchildren for a bit.
I'll post the all the readings in the next post.

Just found broken pc run between R61 and IC3 pin 8.
Standby ...

First I guess I better appologize for not properly responding to you instructions on floating the emitter resistors.
I've been putting in a lot of hours on this amp, determined to get it fixed. I really need your help. So sorry.

at very first power up pin 1 of IC3 = 1.305, and within seconds settles down to 12.70 after maybe 30 seconds.
Pin 2 = .368 stays steady
Pin 3 = .386 stays steady

I've got my limiter built, but can't find a 40 watt light bulb anywhere around the house. Went to Lowes,
they have purged their shelves of almost all incandescent bulbs. No 40 watt bulbs there. Got wife stopping
by Dollar General to see if they have some.

Here is a fresh reading of IC3 pins while adjust AP1 pot. All min to max.

2 = .327 - .366
3 = .327 - .366
1 = 1.567 - 1.241

5 = .294 - .335
6 = .294 - .335
7 = 1.063 - 1.386

They sell 40 watt utility bulbs for your fridge and oven. Also if you see a 60-100 watt bulb should do just fine really. I see them all the time at goodwill because they sat in boxes for years.
