An L Loaded ZV9, Why Not
and such. I just figured that last year, I was working on an LH (PLH) and the Christmas music was fine... But it didn't work out as good as I would have hoped??? I need to get another proto working for Christmas music this year??? Why Not???So, to that end, I'm putting together a ZV9 Gain stage on a big heatsink. I'll post a pic when I figure out I how I did that last. But, Just an LU1014D, with 2 IRFP240's cascoding it, and the load 1/2 above it. I would eventually want that to be a big L thing. And, I have a few. But, I might start with a light bulb or two, ala ZV8, but, waht do ya think??? Thanks... Gotta go cook for the parental units... |

The inputs will need a ground reference. But, if you want to play with the source resistors:

carpenter, are you trying to confuse me
It is something between ZV8 with an Inductor & ZV9 - the Aleph. I'd like to try to get a little more Iq out of it than ZV9, and a little more linearity and effeciency than ZV8. The 2 cascode transistors are due to an eventuall expectation of close to a 37 Volt rail once things seem to work O.K. So what's that 1000uF doin in there FaLaLaLaLaa LaLa La La |

I believe in ZV8 & 9, Nelson uses a gate to GND R in the circuits without feedback. Then when he adds feedback he takes them out...
