Hello,.
Just joined Beoworld. Have owned B.O. products since 09.1974. I bought the above new in 07.1975. I had to store it in my loft, in its original packaging. Imagine my horror and consternation when shown by our local expert boffin the disastrous damage done to the innards by field mice notably the shellac-coated mains transformer. Having now retired and discovered a world of B.O. enthusiasts, and that Jensen classics are cherished, I was directed towards Beoworld by Lee, at Lifestyle A.V. He was confident that someone, somewhere, would have the requisite knowledge and/or access to parts to make my 3500 live again. For ignoring my repair man's suggestion, you guessed it, I could not, and would not junk it. Now that I have joined the 21st Century I bought a Beomaster 2600 together with a Beogram 1700 on E-Bay . The seller turned out to be an expert electronics repair man who owns and has restored literally 100's of radios dating back to the 1930's. He has kindly offered to do this for me and was amazed that the voracious rural mice had not been deterred by the shellac coating. As yet he has not collected or examined my treasured product, this he will do next week. Therefore, I have posted this with the hope/prayer, not to be sacriligious, that advice and pointers towards the right direction might result. Thanks for taking the time to read this.
Keep the Faith with regard to B. O. BEST WISHES to you all out there, TIM.
