The sickness continues. Getting into a 1250 that I picked up recently. 2nd owner had it for 25 years = ~1993. Here is what I found = looks as if it has never been opened. All the lamps look original and were working. Need of a good cleaning - working through that now. It adjusts outs very well: Main Rails: Bias - Each Channel (read a bunch about setting anywhere from 70mV to 100mV). I elected 80mV. DC Offset - Both Channels: All I can say am pretty impressed = 40+ years later and she was not really far off with original components. Maybe I should leave well enough alone, but I going to do all the caps, trimmers, + relays. Here is the lights (all changed). Four Dials & Nine Indicator Lights. The 1250 looks to be very easy to work on compared the other units I have completed - plenty of room. Am finishing up the cap list (based off of MTF / Mattsd posts)... but I don't think I am going to wholesale the transistors. I will share in .xls format shortly. There are a few folks here that have done more than a few SX-1250 (and are miles ahead in experience on this unit) = what transistors do you all recommend being replaced for increased reliability or improved sonic performance. I might just ensure I have them all in stock and place the order later today (minus the main outputs). Most threads are centered around a wholesale rebuild = transistors and diodes. Thanks in advance for sharing your thoughts.
