Model 86 Curiosity
#7

I hope you won't. I am not sure why but the hum seems to originate in the transformer. It is not there before it and not after. A cap across it killed the hum (mostly). But I am still not sure as to the origin. It is possible a new transformer would not do it.

PS. If you come out with a good way to empty the old caps and tar from the box (it is easily disassembled but then the removal of tar...let's just say that I haven't completed it) let me know. I am not a fan of boiling it and the heating (well I haven't tried the oven....I use it for cooking) by a gun did not do much.
Surprisingly in 111 wit ha similar and actually bigger can I was able to quite easily remove the tar with a large screw and a large vice.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
