Eric, WB4VVI(SK), told me that the 6000 tube was essentially a 6L6 with the
pins moved around and filament voltage raised. I guess you can use a 25AV5
as a drop in replacement for it with a little less drive. I have an exciter
deck and got the more common 6AV5. The reason is that the tube's wires for
the filament are on a separate line. Therefore, you could hook-up whatever
flavor filament transformer that will meet your needs.

The T368 exciter deck that I'm using retains the 10
watt Type 6000 tube in there, and drives the 807s
instead of the 6L6 buffer that was in there.
It would be too hot to drive the oscillator module,
plus, I needed the space to park the exciter deck. The
feedline needs to be kept short, I presume you know,
or the coax capacitance gets out of hand.
OK on your timetable, here's hoping you'll be up in
time for one of the big AM events. Maybe you'll even
become a cover boy -- as seen here with No. 147 :
