More SB-200 issues

Fri Jul 3 02:01:55 EDT 2009

Today, while using the SB-200, one of my brand-new Chinese-made 572Bs 
(Shuguang) flashed, and the antenna relay slammed closed and stayed 
closed.

Turned out that the filament had shorted to the grid and the grid was solidly 
grounded....which caused the antenna relay to close.

I also discovered that my HM-2140 peak-reading watt-meter is reading at 
least 33% high. :-(

Anyone know how to calibrate the '2140? 

The manual is absolutely no help on this particular issue.

I think I have to replace a bunch of resistors...
