r253 i meg reolace that resistor

Thanks, that is on my to-do list. Also the second resistor in that photo. I might as well replace the little one, too, as long as I'm in there.

I don't have any 3.3 ohm resistors in the house, but perhaps a 3.0 ohm will do here.

If anyone votes for using a 4.7 ohm in place of a 3.0 ohm, speak now or forever hold your peace. That's all I've got on hand, and I don't feel like waiting 3 days to order one resistor thru the mail :-)

That will be close enough.

Wahoo! Replacing the bad 1 meg resistor cured the arcing.

Now, on to the next problem. Thx for the advice :-)
