Getting into the MC 2505

[Gregory]

One of the guys brought up "Vintage Gear" and mentioned the MC 2505. Since I have some time while the other amp sits waiting for parts, I've decided to dig into the 2505 which still works BTW, it just doesn't sound good!!

The electronics are an interesting example of U.S. technology in the '60s along with the Space Program and the Boeing 727 jetliner, etc. So here are some photos. In just 2 or 3 hours, I've polished it up nicely and changed out almost 20 of the old and cruddy screws.





























Many of the screws will need to be replaced.


As stated.. it's a nice specimen of American electronics, but it simply sounds flat and cardboard-like. The obvious first cut diagnosis is to re-cap, but some of those ganged power supply capacitors are NLA (not available) and other axial lead caps look a bit strange.

What are those components that look like pieces of candy in a yellow, red and white wrapper?
