Hallicrafters Model A84 Super-Fidelity Amplifier

Manual with schematic diagram: Hallicrafters_A84_manual.pdf

Chicago-made 10w Williamson push-pull amp. Somewhat rare (Hallicrafters was better known for ham radios).
Here is one nicely cleaned up, that someone was trying to sell in 2004: ebay item 5740836949

In the two columns below are pictures of my two A84s.
Both worked & sounded great for a few years, until recently.
Now (summer 2013) they need work, so finally I will recap them.
I plan to post some "after" pictures soon.
Serial no. 533. Inherited from my father. Serial no. 217. Bought for $204 on ebay, Mar 2003
