Beogram 4000....an old friend

Been here before as can be seen from the Rudi patented laser printed capacitor bracket, and the ne 6v & 24v power supply smoothing capacitors....cant quite remember what else I did in here but I suspect it may have been a replacement of the 24v regulator OTR1....It comes with the description of "misbehaving" in as much as the tone arm is driving inboard and not returning to the stop position when required....I will have a look.
