- In today's video, we'll do an update on the Denon DR-M3 to see if we can find the problem with the recording amplifier and then fix the not working right channel level meter in the Pioneer CT-F615. Neither one of these decks has enough wrong anymore to do a full video on each, so I'm combining them into one video.

Really enjoy your videos - I’m a fairly new subscriber who also has anxiety issues :) It’s hard to ever find a comfort zone, but your videos do indeed help. I’m trying to fix an old Pioneer PL-600 belt driven turntable - So far the motor seems dead and the power supply was only giving me 2.6 volts - If can find parts on EBay I’ll give it a shot, probably not worth the effort, but I’m on a mission to make it work - Guess the OCD doesn’t help :)
As always very interesting video! Thanks for sharing! Cheers mate!😊
I didn't look at the scheme in detail, only here in the video. Those two transistors act as mute transistors to me. If one has changed it’s parameters, it should be easy to detect with a transistor tester.
Where do you get parts for old tape decs like your Denon? I have a dr -m1? It needs some parts like pinch roller and some other parts. Rewind is painful . My Internet serches haven't come up with much.
It depends what parts they need. Digikey and Mouser for the electronics parts (unless they don't have them), Fix Your Audio for some belts and pinch rollers, other stuff on a case by case basis.
Hello, is there any way to contact you?
My father has an old sony stereo casate deck model number TC-K71 that has sound quality issues, possibly due to motor issues. I am wondering if you could help us fixing this.
Thank you
