Output transistor pin out needed from someone with a known good Marantz 26 receiver
Hi Everyone -
I purchased the Marantz 26 a couple of years ago from eBay. Upon receiving it, it would not power on, tripping the onboard circuit breaker immediately. At the time I ended up removing the power wire that supplied the power amp board and was able to use the rest of the receiver successfully.
The power amp board had been "repaired", which is why I removed the wire from the power supply to the board. I then removed all of the questionable components, finding that at least 2 of the output transistors had shorted out. So that leads me to my current issue. There's signs of an attempted repair around the output transistors. I am looking to verify with someone who may have a known good Marantz 26 what wires go to what part of each transistor (H001-H004), along with the corresponding Pin from the Power Amp Board.
I do have the service manual, but I am not very confident in what it shows.
Thank you!
