Gentlemen,
I located the problem with the hi B+ line in the DX-60B today. I started
at the plate cap for the 6146 final amp and started working backwards,
watching the ohm meter as I went. When I pulled C19, the meter showed
infinity. YAY! Capacitor C19 was indeed shorted. I must have done a bad
job of checking it yesterday. All of the connections to the power supply
now show infinity to ground with the tubes removed.
I think I'm now ready to try the initial tests again. However, I'm in need
of a replacement for R34, a 100 ohm, 7W wire wound resistor. Anyone have
one they could part with? I currently have two 50 ohm, 10W resistors in
series at that point but I believe that's a bit too much head room as far
as the wattage is concerned.
