12, 24, and 48 volts????

That's it in a nut shell right there.

Somebody made a name on the keydown circuit and started building keydown boxes for the masses and in the process all regards for audio quality were lost.


Yup. It has become a world where quantity is everything and quality is nothing.

If that's not an urban legend, lol, that's funny.[/QUOTE

Not sure what your saying, Peakaboo used to build some of the best amplifiers around. He would also take Texas Star amps and re-work them with a regulated bias and probably tweek some other stuff in them.
 
They gotta be swamping the hell out of that input into the GS35B tube to allow use of a driver that puts out 250W PEP.

Insanity? Stupidity? :confused: You make the call.

A lot of builders have already gone to the DEI pills. My buddy got a fatboy last week with DEI and a trucker friend got one also I think it was a Dave but I could be wrong.

30 dollars a pill vs 50 dollars a pill and charging the same price...

In that one move the bipolar RF transistor market has been set back in time by about 25 years. The DIE transistors are more like a cross between a MRF454 and an MFR492. Not even as good as a real 2SC2290 in terms of voltage breakdown. Between the lack of any good bipolar transistors and the end of the solar skip cycle being right around the corner, this was probably the worst time to buy X Force and the best time to sell it.

I'm confused. Could you be a little more clear. Are you talking about the DEI power out put? I was under the impression that you suffer only a 10% loss with them. I am honestly curious you just lost me.
