Re: dynacord powermate service manual

Hi, I guess it is the power amp that's overheating? This is mostly caused by a faulty bias trimmer. This is the one with 100 or 250 ohms if I remember correctly. Replace them on both sides with good quality ones (cermet or similar).
For the bias setting I may be able to find a service manual but it could take some time to look it up.
