Check out the 6CD6, 20 watts plate dissipation; max plate volts 700. The
6DQ6 is a similar tube but onlt 18 watts PD but handles 770 volts. The next
step up will be novar/duodecar compactron color TV sweep tubes which can be
expensive due to the explosion of sweep tube CB linear amps in past
years/decades.

Why not just design it around a 6146?? Easy to find--and maybe free from
another ham.

Best 73.

I am looking for a substitue for a 6L6 that has the plate brought out
the top. I was trying to build a little Glowbug transmitter but was
having all kinds of problems neutralizing the the thing. I think I
would have better luck if I can separate the grid and plate circuits
from each other. I am considering an 807 as a replacement Suggestions
would be appreciated.

To Hijack an old thread...

The way tubes were numbered sometimes....
The 25L6 and 50L6 are NOT 6L6's with different heater voltages.
Actually both of these tubes are IDENTICAL with the 6W6GT except for the
heater ratings.
