Good to hear they're getting some enjoyment out of it 🙂

Did you just rinse it out with a garden hose or what? Looks great compared to what it looked like when you received it.

[@retroelectrotech]

I practically had to hose it down, it sure was dirty enough. I got in there with some small brushes and a "micro" vacuum tip to get all the looser stuff sucked out, then I followed up with 99.9% anhydrous alcohol "misted" onto the boards and then brushed off. Otherwise, thanks for chiming in have a great day !

No offense, but all of that and no tending to the 45-50 yr old speaker relay? Also, the 2SD712 voltage regulator must be resoldered on these without fail.

[@retroelectrotech]

No offense taken, There were a few things I did off camera, cleaning the relay contacts was one of them, and yes sir I forgot to mention it, which I sometimes do when there's a lot going on etc. At the end of making the video, I ended up having to replace one of the the Darlington Packs (STK0050), it was producing some very intermittent noise. That of course didn't make it to the video either. As far as going any further with replacing the regulator, or anything else, I just wanted to get this thing cleaned up and resolve the "channel issue" so I could get it back to the customer. Thank you for bringing up the info concerning the voltage regulator, that's good advice / good info. Again, I appreciate you chiming in.
