Hi all, Firstly, about me, I am writing a book on the restoration of HP calculators from 1972 to 2000. In the mean time I have a collection of restored reverse painted 6 transistor radios. Recently I have graduated to tube radio restorations and have a beautifully restored Normende Electra from1964. I completed the cabinet and internal restorations and it now sits in the dining room. I will post pictures later. This brings me to my latest acquisition, which will require some cosmetic work. The radio is an RCA 5QR 74M. The cabinet is scratched and some one has done a hack job on the grille fabric. They have also removed the metallic fretwork. The material is easy to replace, the electronics should be easy (have not plugged it in or tested it yet), but where does one find the fretwork? Is there an online source? I have tried the google approach with no success. Next step, with emails from you, will be to visit my club, SPARC, and see if they have this model in the parts room. Any help on sourcing the grille would be appreciated. I will be posting a step by step article on the cabinet and electronic restorations. Also restoring an older version BEOLIT 600. Got the FM side working and have just compiled a CAP list for purchase and replacement. I will also document this restoration. This was filthy and covered in nicotine!!! In fact it was completely unserviceable until I disassembled it and washed the electronics in an alcohol bath. After a dry assembly I got the FM to function, albeit weakly. A brief test with caps bridging some of the installed caps showed a cap problem. Until then, thanks for your help. Geoff Quickfall in Vancouver, Canada.
