Hi everyone! Newbie here
I use to work on the tube power amps of Leslies n electronic at Music n Electronics in Mooresville NC. 18 years ago! Have repaired electronics since 91, both in store, n here at home at moment....Retired Navy 95 AViation Electrician
YET....Just brought home from friends house a Power supply n amp section for his HL722..The power supply triac leg was floating in a hole, and the 8 ohm 10 watt resistor was flopping around ( nothing but hum n NO workie wen plugged into organ). Got power supply turned ON,,n voltages look GOOD.....Intend on powering up the supply n amp, in AM.....do grounding nec to turn ON everything, slave signals in, n add a speaker to the 4 amps....... BUT... Im NOT sure how to kik in the MOTOR control and observe voltage for proper operation... Have schematic, n it looks like a signal comes in from to a reverse diode kiking on relay....Id really appreciate some help, its my FIRST one like this, never worked on solid state Leslie stuff at M&E ( just the organs) Have repaired solid state though, n stil do..Just dont know WHAT kind of signal hits the relay!
Thanks in advance!
Jim
