Just got a ceriatone gargoyle and love it. My kind of brutal with a marshally grind. I want to switch to kt88’s. What resistor do i need to change or piggy-back to allow this? Thanks for any info.

According to the schematic you have independent tube bias capability already with a pretty significant swing. What is it you’re trying to accomplish? Researching or trying to bias an already purchased set of KT88s?

IF YOU DO NOT KNOW HOW TO DO THIS TAKE IT TO A QUALIFIED TECHNICIAN:

If you haven’t yet purchased them, You’d be better off measuring the voltage across one of the 1 ohm cathode resistors on the power tubes and also measuring the plate voltage out of standby and requesting a set of KT88 tubes that are close to your current bias point.

Im totally taking it to someone as soon as i can. Extremely limited on techs here in SC, and just trying to learn.

is the gargoyle a modded plexi circuit ??

Its supposedly a meshuggah clone. I dont use the clipping diodes, bit it def has more gain than a stock jcm or a plexi with a master volume. I love it. Just grinding and clear. Just not an el34 guy. I always switch my 800’s to kt88’s
 
Best bet is to just send it to me. I foolishly sold mine. Such an awesome amp.

I waited forever for one to pop up and grabbed it as soon as i saw it. Its really an interesting amp and has just the right amount of saturation and tightness to get the job done.(boosted) But the base tone and mids are just crazy good. Not honky or shrill. I took my rev g home to sell after one practice.
