  • Pre Airline Montgomery Ward 55JDR8440

    Anyone have a schematic for a Montgomery Ward 55JDR8440? Or something akin using 6SJ7-6SJ7-2X6V6-5Y3? Not even sure who actually built this amp. Dano maybe?

    Should be simple to draw up a schematic from the unit.

      Thanks, Enzo, but the problem is that someone has been here before and I can see several places where component leads have been cut but no new parts have been connected there. I'd like to see how the circuit was wired originally if possible.
      I know this may be a tough schematic to find

        AMps tend to be very similar. Draw up what is there. Then we can easily see glaring omissions and infer what ought to be. In other cases, we might find things like someone cut out a cathode bypass cap to tame gain. If we see clipped leads where a cap ought to be across a cathode resistor, mystery solved.
