(ET) low charge

[Neil <wombat dssinternet net>]

Ray, the probabilities are good that the capacitor on the power supply 
is bad, that is the usual cause.  You can check it with an ohmmeter 
easily.  A warning, don't try to check it when the supply is turned on, 
that's dangerous.   Disconnect the capacitor from the transformer, then  
when you put the meter across the leads, the needle should "jump" and 
then  drop back to an "open" (very high resistance) indication, no 
"jump" is open , a low reading is shorted (bad).

wombat  - if it is bad, be sure you replace it with the identical ratings
