Got ya, I probably had it opposite, mirrored. It would be g1- 6.7, g2 9.8, plate 118, cathode 143, does that make more sense.

Not really. The question remains, which topology is used? The numbers are still odd.

Just for comparison, here is the LA2a drawn slightly differently. Note the sidechain amplifier. Check if this is somehow similiar to your unit?

It looks like c11 is the equivalent of c26 on the la610. Which is a 47nf 450v film capacitor. The voltage stops after this capacitor. Thanks for the feedback I realize I need to find a local tech. for this because it’s definitely beyond my knowledge and I apologize for that.

If the voltage stops after the cap.
Can you confirm the cap is testing ok?

 

[mrsoundb]

Yeah it tested ok. I also replaced it just in case.

I think this is the best and safest way to solve the problem. I hope the channel strip will soon be available again for your work and music.
