I have just joined this group and hope that my question is on the right track. I have acquired a?Drake L7 amplifier that was in excellent?condition. I have performed the Harbach mod to the power supply and added the diode protection for the meters. The manual outlines a procedure for CW and SSB, which I find somewhat confusing.

Does anyone have a tune-up?procedure that they can share with me?

Thanks,

Ig Justyna, N?EFT
