I finally got my ass in gear and actually removed this thing from the box it was shipped to me in......6 years ago. I know, right! I bought it off eBay with intention of going through it and using it, but it just never happened. Till now. I bought a recap kit back then, so I started on the amplifier modules. I guess who ever built this one had the mylar kit as the original used the ceramic disks. I didn't have to replace those, I just did the electrolytics. I ordered new PS caps and installed those. I didn't upsize those as this thing will never be running all out, it's going in the living room for TV/music duty. The spec'd 10Kuf will be fine.
I replaced the RCA Jack's with some nice goldies and ran shielded wire to the boards. I replaced the 10uf electrolytic input caps with poly units. These amps were usually described as light on bass. After running the ESR numbers on the original caps, I see why. At 120Hz the electrolytics were 15 ohms!!! The poly's 2.5 ohm, and bested them up top, too.
Last thing was the power cord. It had a standard 2 wire "lamp cord". I ditched that in favor of an IEC standard plug. Little Dremel action took care of that.
It sounds great👍🏻 Cant say its better or worse than anything else, but there's no noticable bad things happening. It definitely has plenty of bass powers. I popped the speaker protection fuses, that's good right? 😂 It had 2A in it, supposed to be 3-5A. I put the 3's in it.
How about some pics?
