Bedini GT3
FRC,
I did want to answer you, Yes I did developed high powered tube amplifiers in the mid 70's using 6LQ6's as output tubes . But before that I worked for TRW in the semiconductor division where I helped developed high power Silicon Sonar Transistors I used some of those Transistors for Acoustic Control in The Model 400 Amplifier you can see them on stage at the Rock concerts (The Big Blue Front Panels). After that I developed the first Dual Differential drive Quasie outputs, it was the first, after that you find, Ampzilla, SAE, Iverson, Crown, Carver.
The late comers were Krell and so on. I did Prototyping for RCA on the 1B05,
2n3584, 2n6211,2N3440, 2N5416 transistors in my shop along with all the new HEX Fets, I still have a good selection of all the devices, that is why you see the odd transistors in some of my circuits. I also built many Rock Transistors in an oven I have. I would take the Transistors cut them open and build circuit in them and pot them back up, I showed Peter L how to build Oscillators right in the devices and the negative effect in those devices.
One of the most important things is the SOA curves you can't do switching without it at low frequency. But those days are over, now it's China junk copy devices.
Some of the amplifiers are the Bedini, 25/25, 50/50,100/100 250/250, 801,802,803, Photon Beam Coupler, B.A.S.E. My shop is full of this stuff. But energy was always my first love and how to get it out of things around us. I will never quit doing any of this.
