Hovland HP100 service?


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

I own #1029 and have contacted the recommendations above because I too am having V-control noise.
They may be Holco resistors. I know Holco's had issues with high voltages. They would become very noisy.
Thank you all. 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.
