@djsumdog I had a treasured Onkyo power amp; stolen in a burglary in 1982. 🙁

That sucks ass. I've only had their home theater receivers. I only learned about their hi-fi amps recently. They released a 2-channel power amp last year. It's not too expensive by hi-fi standards, but still up there.I have a Willsenton R8 tube amp, but I sorta used it for everything and tubes/repair can get expensive. So I'm working on building out a setup with a Douk Audio speaker/amplifier switch so I can easily switch between two amps, and then only turn on the tube amp when I really want to crank some music.

@djsumdog That M-504 is an impressive looking bit of kit. The Onkyo I had was at the absolute bottom end of their power range (60W?), and I can’t remember the model number. It was from before the era where Onkyo switched to black finish for all their equipment (in the 80’s?). It had the silver finish, with two rows of colored LED’s arranged vertically to display instantaneous power. This conversation prompted me, once again, to go on eBay and look for that model, but alas no joy.

I ended up ordering the one in the picture off of Reverb. The listing didn't say it had been serviced or had photos of the case opened up. I'm a bit weary of vintage stuff like this, but it's less than half the price of the new Onkyo M-80.I'll test it to make sure it works, but after that I'm going to open it up and make sure there's no corrosion and no leaky caps. The glue on these can get conductive if it gets corroded by leaky caps, so you have to clean it really well after you de-solder them.Hopefully it's been in use and not in storage, which can keep caps from breaking. If not, well, it will be my first recapping project. 😅I'll be using this Douk to switch between amps, and a Douk D5 as the pre-amp from my DAC to both amps. The switch has good reviews, but there is nothing on the D5, so hopefully it doesn't suck.
