Red 34,5
T1 182
T2 ? 6
R34 = 0
R43 41

Yes, open up to give it a visual check. You can pull the connector (3rd pic down) to measure the voltages.
Be careful.

I already pulled the moltex connecter, as i wrote down the messaurements of the connector

Didnt saw any burnmarks in the PSU, but i might be wrong, whats next to check?

Thanks for the photos.

From your measurements.
All is fine.
R34 shouldn’t get a measurement. 0v at R34 is correct.
Your voltages sound within tolerance.
Have you replaced tubes yet?
Have you replaced any of the 10uf and 100uf blue capacitors yet?

I already replaced tubes, no i didnt replaced any of them, should i?
are these the right type of capacitors? i think bout 25 of each of them should be enough, let me know if u think otherwise

Well let’s go back a minute before we do that.

What is the issue exactly?

Can we confirm the unit is passing signal properly?

So the problem is the following, I get only a very thin, very quit output, also its noisy neither the line or mic works properly

Show more photos how you have it connected and how you have it set up as far as the controls.
