[Drake] L4B plate voltage

[Garey Barrell]

John -

My L-4B is in storage, so can't tell you for sure.  I believe it's 
around 2500 on HIGH, and about 1700 on low,  _under load_.  Probably 
about 5-10% more no load.

The resistors Drake used are much better than what Heath used.  The L-4B 
has DALE wirewound 5M, 1W, 1% ceramic resistors.  They do not change 
value unless they break for some reason.

Also does anyone know if the voltage multiplier resistors  age and change value with time to the point that the Heath SB 220 resistors do? Anyone had trouble with that using an L4B?
