Rockerverb 50 reverb(?) issue

So, my RV50 MkI Head I haven’t played in a good bit is acting up. With the reverb knob turned down or footswitch in the off position, the amp sounds normal. With the reverb on, the tone becomes more trebly / harsh as you turn the knob up. There is no reverb present at any setting. It also has a low hum that increases as the knob goes up. I’ve checked the tube and that isn’t it...anyone have any idea what the problem is? It was working fine before I sat it up. Thanks I’m advance!

Man, that sucks.....

Have you tried removing and resitting the valve?

Unplugging and replugging the reverb tank wire?

If you're sure the 12AT7 is good, there isn't much else you can do yourself. :(
