Thanks again Hiort.
That BM3000 looks mint – hard to think it could be nearly 40 years old!
I’ve managed to get a BM3000 with remote now (£170) and a Beogram 3000 (without cartridge) for £140. Both in good condition and fully working.
New (non OEM) stylus is ordered too so last thing to get are the speakers – when I started out I had no idea that the cartridge would cost around the same as the main parts of the system!!
Am waiting to get a response to questions on a pair of CX100 – but if they don’t work out I think the S45-2 mentioned will be the next one to try.
I should have done this years ago.
