Good afternoon everyone. I have decided to restore the two amps in the 41 and 42 and I would like to ask for your help from all of the knowledgeable people on this forum

Thank you.

All of the readings are voltage.

R14 4.95v
R13 7.4v
R8 1.3v
R16. 0v
R5. 0v
R4. 0.85v
R21. 10.7v
R18. 0.01v
R19. 0.01v

C3. 0.87v
C5. 1.3v
C9. 7.3v
C10. 7.5v
C8. 236v
C16. 253v
C7. 137v
C6. 136v

I hope some one can help me as I don't want to go changing things that don't need changing these readings are from the AL41.

Many thanks.
