Mike;
Yes I think the R-7 Superettes, and their sister models are pretty bad, especially if you have never dug into one before. The ones I worked on were the Canadian G.E versions, and an Canadian Westinghouse 801 Columnaire, which uses a similar circuit, but in a different chassis, it was much easier to work on by the way because they mounted the #80 and the two #45s on one end of the chassis. I've never actually worked on an A.K, the only one I have is a model 20C battery set, but have worked on lots of Rogers built sets, some of those are not fun with the stupid resistor boards.
Regards
Arran
