grrr arrrggghhh

dicking around with the h&k this morning. the good news: the tubes all appear to be intact. the weirdness: when i take the back off the cabinet and have the works outside with the footswitch connected, the hum in the overdrive channel doesn't occur, even when i play at volume. but when i put it back together, the hum returns, and sometimes persists even after i disconnect the footswitch. wtf?!?!?

Loose ground somewhere? With the guts out, maybe they are grounding on the table, but with them in the chassis they are floating. Maybe the input or footswitch jacks.

I should also mention that I know next to nothing about amp repair :-)
