Upgraded McIntosh MC275 Mk1 tubes These Denons have very cool

Upgraded McIntosh MC275 Mk1 tubes These Denons have very coolHere's a fantastic McIntosh MC275 MK1 amplifier. The power supply caps were replaced and the amplifier is performing flawlessly. I installed a new cord for safety. The chassis is original with patina and a few flaws. The bottom cover is free from rust and corrosion. The transformers still have their original decals and the paint is original. There are 2 spots on the chassis towards the middle with some scratches. I'd rate the exterior cosmetics as 8
