Accuphase P-300L Power Amp Repair III - Parts Replacement
This is one of the challenging repair work I have encountered. Because there is no access of wiring and circuit diagram, I have to use the labels marked on the parts and the traces at underside of PCB to figure out a circuit schematic for the repair use. So far, I am happy with the result of the work and hope all the DIY fans enjoy watching the video as well. I welcome all the comments and questions regarding to this repair. (Please note - the schematic in this video is still under verification, no accuracy guarantee)

As usual a fine job at troubleshooting and repair. Always a great soundtrack too. Thanks

you can compare right and left channel on oscillo to see if there is a diffrence
Great work, I like to know the transistor have to match pair before replace or not

Very nice 👍🏾
Well done for this great repair ! Don’t you want to change the same components on the left channel to keep it balanced?

Thank you for the suggestion. It will be the project in the future (I already bought enough parts for both channels). My short term goal is trying to make this P-300L back to life again.
