Hi Dave,
Good the chat with someone from Wallace and Grommet land. You should ground the metal part of the chassis. You could try attaching a .01@600v cap to the hot side of the mains to the chassis to see if that helps. I'm suprized you didn't hold out for a model 66MB. Same cabinet but has much better shortwave coverage like 6-12mc instead of the worthless 2-3.5mc.
Don't know of a good book for repairing but if you are interested in theory and construction The Radio Amateur Handbook is great. Just have to get an old one from the mid '30's- '50's. Easy to find on epay.

Hi Terry,

Grateful thanks from over the pond!

Grounding the chassis has done the job!!!

If I need advice in the future I'll ask you.

Will look out for the book on ebay.

Truly
Dave
