I second that!
I've been running one @4200, or so, since '85 with no issues.
22 watts in gives me 1500 out. A 3 db pad sure would make it less touchy, when
tuning.
## 22 in and 1500w out = 18.34 db gain. Use a parasitic suppressor..and a
glitch R. .

## I thought the 8877 required more drive than that...like 60w.
I heard that once the B+ gets up above 3900....that the gain of the tube
increases a whole bunch.
Plan B is to use a pair of tubes..and run em at 3-5 kw pep out.
## IF a pad is used, insert it inside the RF deck... just prior to the tuned
input. Then the pad is
not in the circuit on RX.
