RE: Q About Edcor Transformer Performance

That's a good point, something I've been looking at in SPICE. Remember I said this won't be a conventional design? Well, just to provide a few more details, the output stage will be a funny-looking single triode with an anode cap. It will be configured as a cathode follower, with the anode connected to chassis ground. Negative voltage will be applied to power the tube from under the CCS (or choke/transformer). This design will allow me to leave the tubes exposed, so their unique physical characteristics will show, without the need to build a glass cage to prevent a shock hazard.

Speaking of all this, I noticed last night that LTSPICE didn't like it when I reversed the voltages in this way. When I grounded the anode and applied B- to the previously grounded points, the CCS stopped working. I need to look at this again, just to see if it's a simulator bug.
