[Heathkit] RE: SB-200

[Cam and Juli Hedrick]

I have an SB-230 that I reworked into a SB-200 style.  My output is 620
watts keyed down.  Amprex 572B tubes in it and are great tubes....20 years
old, but only 2 years use.  Meter 2500VDC and .520 ma, hmmm, a nice
amplifier saved.
Anyway, the Chinese 572B tubes are also good now.  I tried them in a AL-572
amp and then 1350 pep output.  They are now 3 years old and working fine.
still.

Good luck,
Cam
