I have been entrusted with a really nice BA-F1 to restore for an AK member, I collected it last night. It is in at least a 9/10 condition overall, and appears un-molested inside apart from a replacement set of OnSemi output transistors for one channel. He is not expecting it to be finished until early next year - so I have plenty of time to make a really good job of the restore. The restore I'll probably post some before and after PCB pictures if there is interest, as this model doesn't seem that well documented / illustrated here on AK. Any tips? For those of you that have already tackled one of these I would be very interested in any tips you may have picked up regarding this model. I am also interested to know if anyone knows the whereabouts of a guaranteed one channel set of OP transistors going spare anywhere, the originals in the other channel are NMC1012 // NMA1012. (The OnSemi replacements used are MJ15024 // MJ15025 which are fine really - but maybe originals are better). Pre-amp? The owner really wants to get a pre-amp for it, I have suggested he does everything he can to get the CA-F1 - the perfect pairing.
