SB-102 Plate Current

Fellow Greenies,

What might cause the Plate Current reading to be too high when apparently
everything
is tuned-up and at resonance? Using normal 50-ohm Dummy Load.

Just noticed this today; don't know how long it's been this way.
On 20 and 15 mtrs, Ip indicates about 340 ma.  Full scale Ig.  Normal
Pout.
10-mtrs also 340 to 350 ma; but it's Ig is low.
The manual says Ip should be about 250 ma.
Bias is apparently right----50ma Ip in the Tune mode with MIC level full
CCW.
Vp is normal: 800vdc. Don't yet know about Screen voltage.


Could poor tracking of the two variable caps for the Driver/Presector do
this?
(But, the belts look OK.)
Would neutralization be a factor here? (No signs of a need here,
however.)

Anyone notice this situation in their rig?

Thanks for ideas/help.

Allen
