I have no voltage in the speaker terminals.
This is a learning process for me and I am by no means a certified tech.
I don't know if all I have done so far is correct but here and some things I have done with this unit:
I have recapped the power supply and the driver board. I also do this on all the units I work on. I like to solder.
I replaced the 2sc458 transistors in the driver board with 2sc2240's. I read another forum on AK that said they were OK to use. I did check the orientation with my transistor checker. I just turned the 2240's around. Hope I did it right. Didn't effect anything that I could see. I am running it on a DBT. The 75 watt lamp is very, very dim. I also pulled and checked the 4 outputs transistors which were all fine. I checked all the other smaller transistors and all were fine. On the power supply board I found a resistor on HW4052 that was open. It looked like a 23 K ohm? It was hard to see the bands and I can't find it in the SM. So I guessed at it. It looked to be red, orange, orange, silver. I tied a 22kohm and a 1Kohm together and replaced it but still no relay. I also looked for cracked solder joints in the power supply and driver board. I did re-flow the power supply board.
Ready when you are to go further. Thanks!
