Ordered some 2SC3502's earlier this week (heyyy, Mouser upgraded my shipping for free!), among other items I needed. I set up approximately the same circuit described below. With some puttering, I've got a pretty nice 10MHz bandwidth out of the thing, including peaking coil, emitter compensation cap (on only the output stage: the MPS3653 and 2N3906 "half diff" and volt amp stages are amply fast on their own, giving
Here's something close, http://www.ortodoxism.ro/datasheets/nationalsemiconductor/DS005507.PDF but it may not give the voltage swing you want.
Do you guys remember when tuner's used tubes to tune UHF. Tim hasn't been forthcoming with entire spec, frequency range, distortion, power output, and voltage Vp-Vp/current output, have you Tim? Ken
Yeah, I want it in the 200V supply range.
I do, if not personally. I have some 6HA5, 6AK5, et al., even a pair of Nuvistors laying around.
No, I haven't. Funny how that is. ;-)
