Hi gang,

I picked up a AN/URM-25D to tune up the 390A with, and because I needed
a decent sig generator anyway (can anyone say 'Eico'?).

After cooking it in overnight, I noticed condensation on the inside of
the meter glass.  What's up with that?  Do I need to bake this sucker
for a week, or what?

Also have a busted  6AH6.  Anyone got a spare you can let loose of?

TIA

Jim
