Re: Crunch channel losing gain intermittently? Preamp Tube?
I’ve been finding this happening with mine quite a bit, except on mine I get a high pitched whine, and unless I strum really hard the gain channel is crackly and muted. Just discovered my 2nd stage 12ax7 gets loose from vibration. Out of curiosity, what position is your ecc82 in? I got mine used. Lo...

HT stage 60 PCB pics
Hi everyone! Wondering if someone might be able to help me out with a couple of pictures of the main PCB from a Stage 60 mk ii. Mainly close ups of the area around the filter caps. A friend of mine got one cheap secondhand. He gave it to me to look at as there was no output. I found a capacitor had ...

Re: HT1 emulated out
The short answer is yes. You’ll need to keep the output very low because the amp is expecting to see a very low level guitar signal. You also can’t defeat the speaker emulation, so that will effect your tone. A better option is to run it into the effects return which will bypass the preamp of the mo...

Re: bias circuit not adjusting HT Club 40
Hope you find an answer to your problem. I have a stage 60 that had a blown cap which cut power to the plates. After replacement I could get sound with no headroom. Adjusting the bias did increase the headroom, but would start to cook resistors. I could not get any reading from the bias test point. ...
