I have an old HP100 and it is doing the volume pops and terrible hum, the right channel wont work at all. Anyone know who can service this? Thanks

Phil, is the email from Steakster the right email? Brf, I tried new tubes, no luck. I did some research and it appears that this was common on the older units with the black resistors on the volume control. I am getting tons of feedback and hum and one channel is completely out.
