Hi. I just bought an Otari MX-5050 B3-2, with stand. It seems to be in decent shape - physically the only real issue is some scratching around the splicing block on the head cover, which is to be expected. The S/N indicates that the deck is from 1997.
This deck didn't come with any manuals. I found and downloaded a MX-5050 BII user's manual from the net, which is helpful, but what I'd really like would be the user's and service manuals (or at least a schematic) for my deck. I'd like to POOGE the recording and playback amps (upgraded caps and opamps, and power supply tweaks), but I'll need the circuit info to do that.
Does anyone have a source for these manuals? Otari has some pdf manuals on its website, but none for my deck. Pdfs or xeroxes would be fine.
BTW, my deck is 2 track only. But I also located a headstack from a MX-5050 B2 which has 2 track record & PB and 4 track PB. It looks like the B2 headstack should be a more or less drop in replacement for the stock B3 one. If it isn't, it looks fairly straightforward to swap the 4 track head and switch onto the B3 stack - the mounting plate and PCB appear to have provision for this. I'll let the group know how this goes.
Thanks!
