need help to fix mysterious hum problem

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

Hello,
I'm sure this topic has come up many times. I did some searches but haven't found anything that is quite like the problem I am experiencing. I've got a low frequency hum coming from my Eico 2036 integrated amp. Here's the facts:
1) it only occurs at startup and gradually goes away over about a 5 minute period.
2) only the right channel is effected
3) changing tubes around has no effect, stays with the right channel
4) switching to a different source has no effect
5) it responds to the volume control, open the pot up and it gets louder, close it and the hum goes away
6) I've sprayed Deoxit on all of the controls
7) I bypassed the channel blend and tape monitor switches, still got the hum
Does anyone out there have any idea what's going on here? Any help would be much appreciated. Thanks.

Bill
