Hey all, just started getting a problem with one of my amps. I am getting a rolling like static fluctuating and constant that is directly affected by volume ( no volume no static, turn the volume up and the static goes up) I have swapped driver and power tubes as well as cables, and determined for sure it is in the amp, where do I start??
-
If it goes up and down with the volume setting it seems the noise would be coming from a component ahead of the volume control.

Hey Doc, mind is mush right now, what does this mean?
-
If that static goes away when the volume is turned down, and goes up when the volume control turned up it stands to reason that the noise is coming from a component that is ahead of the volume control.
-
It sounds like the noise is before whatever controls the volume. Let's assume you swapped tubes and the inputs to the Paramounts one at a time.
It sounds like the noise was in one channel. And it didn't change channels with either of the tube swaps or the input cable swaps. But the noise stayed in one amp, right?

Yes, throughout all swaps it stayed in the same amp.

The mystery is why it follows volume. Your problem sounds like what happens to my amps every 9 months or so. I changed the drivers and the 76 tube sockets get loose. I have to reseat the tubes several times to cure it. If that doesn't do it I have to take needle nose pliers to my ceramic 5 pin tube sockets. You have better sockets than this.

I tried what you suggested Grainger and it seems to have worked!! Thanks man!!

Years ago I bought a tube socket cleaner. It is a tiny brush like women have for their eye lashes and a contact cleaner. That works well for 9 pin sockets but it is a really tight fit in the socket.
My sockets for my 76 need to be replaced. It is an ill conceived design that loses its tension as it heats from the tube. I don't often see another 5 pin socket.

Hey Grainger et all, can I use this set of sockets to replace the existing sockets in my Paramounts?? http://www.partsconnexion.com/CONNEX-73300.html

I have a pair of those exact tube sockets for my Paramours. I haven't put them in yet. The only drawback I see is that there is no hole to crimp the wire onto before soldering.

When you get these sockets installed would you report back, I cracked one when installing and would like to replace it.
Thanks,
Steve
