Tube Amp Archive

thanks for that . Yeah, i've tried the PPIMV and am still on the fence with it. I feel the sound gets way too compressed and doesn't sound like a jcm800 at all when it's used. I like having presense and negative feedback/"depth" control. So i guess my question is will the VVR keep my "cranked tone" ...

so i am researching heatsinks for the mosfet- any suggestions? I would mount it outside the chassis as well.

I still haven't heard if its worth all the trouble to even install the VVR on an 800.

Thanks Dass! It seems like the only thing i've heard so far is that heat will kill the mosfet in time.

Has anyone installed a VVR in a JCM800 with good results? I am contemplating doing so and wanted feedback from others.

Did you scale the whole amp or just the power tubes? with or without PPMIV?
