I might have some side panels I can spare, but getting from two people is a bit unwieldy especially post-Brexit from the UK - are there no cheap junk modules on ebay?
I got an AM503 for 30 quid just as covid hit, which is probably one of the more useful modules (was expecting a parts unit, but all it needed was a dry joint to be touched up and then was 100% OK, including early-80s electrolytics and wet-slug/dipped tantalums).
