Anyone had a go at using mosfets for phase inverting?
Reading and about to try some curious implementation of fets as followers. Will report what i hear, but im also interested in phase inverter use as well.
I think as long as theyre not used where usable gain is being made, they could be very useful, both cheap to obtain and last forever, as well as accurate reproduction of preceding stages.
Maybe heresy, but who's afraid of a little fire
Blackstar (HT-series) amps do it. They use a MOSFET LTP with a constant current source tail. The earliest Vox Valvetronix amps also had a MOSFET PI before the 12AX7 power amp emulation stage. I think I've seen a few others too but can't remember what they were.
I used to watch transformer PI. I loved that show. His friend with the helicopter and that english guy on the estate and he would look like a 308 and drive around then turn into a robot.
Signatures have a 255 character limit that I could abuse, but I am not Cecil B. DeMille.

Though having a mustache on a transformer can get pretty stinky, especially if you don't wash out the food particles.
I played around with an LND150 as a cathodyne, it worked very well. You just have to design it so it doesn't get overdriven. It was completely transparent to my ears.
In my case, I used it to feed both inputs of a LTPPI, ala Marshall Major, to drive the PA harder.

(which have a crystal lettuce structure)
Go to the local library and do a search, tubes are finished, this transistor thing is going to change everything. Soon everyone will have personal computers the size of an attache case and you'll be able to use a payphone with a credit card!
