Well dang.  i hooked up  to c138 to measure the range of voltage from q101 and what do you know compression led lit up. So i had a cold joint .
Looks to working just fine now. Set the compression circuit and and now works as it should.

Sorry for the delay guys.  I will pull out the scope tomorrow and check signal.

I followed these procedures for setting compression and nada nothing.
Dummy load
all tone set flat
master CW
Compressor off
Dial up till output reaches 28.3 VRMS with 1khz sine 100mv into low jack
Turn compressor on set to zero adjust r186 till led starts to fire.

thats the instructions from the lab series notes.
Will check on signal tomorrow and flush slide switch and pots.

Thanks guys

Amplifier Discussion / Lab5 Compressor not engaging
August 14, 2023, 06:06:28 PM
i have a Lab5 that seems to be having a issue with the compressor not engaging. The way I understand it compressor rolled all the way to the left at -18 should be the most sensitive but it doesn't seem to matter any position of the compressor knob. it just doesn't work. Any help I can get would be greatly appreciated.
When powering on sometimes it will light for a sec then go off so the LED is good.
Thanks,

Was there DC at the speaker?  If so  lightly take our hand and push the speaker in, it should move smoothly, if it is stiff you may require a new speaker also.  I just had a Kustom powered subwoofer with that chip last nite that died taking out the speaker with it .
