Hey Myles here`s a post from the main forum maybe you can help point me in the right direction with. I`ve got a Vanous.Its a hybred amp-solid state power -tube pre-amp.There`s 3 channels,one clean,2 overdrive.2 tubes in it[12ax7`s].The clean channel works fine but after about 1/2 hour of playing the drive channels both kind of fizzle down in volume to just barely audible.If i turn it off for a minute they come back but not for long.I replaced the tubes and it did the same thing-worked for about a set and then fizzled on the last song.Clean channel unaffected-works fine.Anybody have any idea what could be the source of the problem?I hate taking my amp in for repair blindly-with an intermittent problem like this.The only possible cause i can dream up is that when this first happened i noticed the output on my pedalboard had been cranked-so when i kicked in my solo boost[about 10db on top of the cranked output knob] it was hitting the amp pretty hard.It was during that set that this problem first occured-i didn`t notice the output knob having moved untill after the set was over.

Hi Myles i`ve been brushin` up on your website but i`d still like some advice straight from the horses mouth!I`m going to launch into some very untechnical terms to describe what i`m looking for so hopefully you`ve delt with enough guitar-speak to figure out what i`m trying to say.I recently bought a 4 channel ,George Dennis 100 watt head that is stocked with 5 ecc83 pre-amp tubes and 4 e34L power tubes.It`s czech so i guess those are 12ax7`s in the pre-amp stage.The distortion tones are a little on the FFRRRRAAAAAAAT side instead of the chunk-kind-of sound i`m used to-almost more like a big,warm ripping fuzztone.This is cool for some things but all round i`m wondering how i might monkey with this to get more smooth chunk and less ripping BLLLAAAAAAT out of it.[i realize i`m soon to go into the idiotic guitar player hall of fame here].In some ways i guess it sounds a little more like fender distortion.My previous amp was a Vanous[which you`ve probably never heard of either] and before that a jcm800-2203-both of which i could get the chunk out of.Any advice would be appreciated!!!
