[Amps] SB 200 problem

No, but you should be able to use a Schottkey diode it would have
a similar low forward voltage drop.

The meter is not functioning in the power out position.It reads fine for high voltage, grid, and SWR functions, just not for power output.   I have to use an external wattmeter to tuneupand check power output. I thought it might be just my amp until the other day when I was at a ham friends of mine, and he told me he had the same problemwith his SB 200. Anyone else had this problem and know what to do to fix it?
