RH50T problem

[Clypher]

Occasionally while playing my amp will suddenly give out and all the gain will be gone, it will be fuzzy and i will just barely be able to hear my guitar in the background. It sounds exactly like the volume knob is turned up only enough to hear the slightest bit of the guitar. This ONLY happens on the dirty channel, but after it happens if i switch to the clean channel it's also silent. There are two things i can do that bring it back to normal. If i switch it to standby and to the clean channel, flipping it back on usually fixes it. If that doesn't work if i strum a chord very hard it seems to kick it back into gear. It happens very sporatically, so far it's only happened in the first 30 minutes or so of playing each time i sit down and play.

I tried wiggling all the connections and it doesn't seem to make a difference in that state.
I pulled all the tubes and placed them solidly back in.
I tried a different guitar, still happened.

I have been told it could either be a dirty jack, the output transformer, or a bad tube. All the tubes glow nicely. Taking it to a tech isn't the easiest solution. I don't know of any that live within an hour's drive of me.

Thanks for your help.

I should probably also add that on the web site it says my amp has 8 and 16 ohm outputs, yet on the back of my amp it says 4 or 8.

one more thing, the guy i bought my amp from lost the footswitch cable. it says 6 pin din beside the socket, would one of these do the trick?

No, the Randall's use full-size DIN plugs... the one you've got there is a mini-DIN.

Not sure of the best place to get a 6-pin DIN cable, but if I can find one I'll post back. Pretty sure my old Marshall TSL used one... I had to buy the cables & connectors separately and build the cable myself.

I have same kind of prob too. After 10-20min playing od volume goes up and when I change clean ch. and back od volume drops back!? What that means? And that happens only one time when I start playing no matter how long I play.
