    Default 50 watt non MV quest

    So in my quest for a 50 watt non mv head I've decided on a boutique version built by Roy Blankenship ... http://www.blankenshipamps.com/variplex.html
    He recently moved back to L.A. (he was my amp tech for years) and because we have a long time client/friend relationship he'll build me one of these for the price of a good plus condition early 70's JMP 50. At least what one goes for out here. White with a silver face plate.

    Nice one Ken. Where is the VariPlex located on the amp?

    The variac is separate and plugs into the back of the chassis via a speakon connector. It's integrated into the circuit.
    I'm not exactly sure how it works - it's proprietary to his design.
    You can get the amp w/o the variac option as well - straight 50 watt non mv.
    I haven't completely decided on the variac option yet. I have a month until I need to make up mind.
    The variac would be nice for quieter situations but, initially at least, I was not wanting one of these to be quiet.

    Sounds like it will be a beast dressed up in a pretty little package - cool!

    It sounds similar in principle to the Vari-Watt that I installed in my Bandmaster Reverb. If so, it varies the B+ (voltage) to the power and preamp tubes and also adjusts the bias so it tracks with the changes in B+. In doing so it lets you vary the wattage of the amp. I love it in my amp. It lets me run the Bandmaster Reverb on 7-8 at an appropriate volume for any gig I play, from outdoor fair shows to a small church, and the tone stays pretty much the same. (Obviously there are differences in how we hear loud vs. quieter sound and differences in how hard the speakers are pushed) With it turned all the way up, it shouldn't sound any different than the amp would with out it. It's not in the signal path, or between the amp and speaker, it just adjusts the voltage, so if the voltage is the same with it on 10 as it would be without it installed, there should be no change in sound.

    From what I was able to understand(?), it sounds like exactly what you just described Blueslyne.
