[Amps] brass or BNP hardware

[DJ7WW]

The mentioned 4-125 was always white and I never had to change the tube.

It sat in a modified HT41 chassis.
Later I added a second tube and returned the anode voltage from 4KV to 2KV,
switched back from bridge rectifier to two-way rectification.
That was in 1977, since then that amp is still in use at a club station with
the same tortured tube and its sister loafing at 800W out.

At 1500 out a 4-400 key down is almost yellow, I tried one at 5KV once which

was enough.I cant imagine any surviving long that way.
