Anyone done anything interesting with one of these? I've had it for many years (maybe since 1979 or so) and it's still going strong... and I've been thinking of (always a dangerous sign!):

- tracking down the output circuit and trying diff op-amps, coupling caps, ps bypass caps, and regulators

- adding a 2nd ps just for the analog output

- upgrading the output jacks

- HD power cord

- better connectors for the antenna

- chassis damping

Sounds like a fun weekend project!
