Check the rectifier first. If that's not it, then it's probably one of the
output transistors. Those are the only two types of failures that I have
seen on these tanks. Add a small computer cooling fan to the interior and
you'll be flabbergasted by the temperature drop.

yes thanx
but this is a banged one ,i got at a flea market
the ouput transisters are both nte 181 is that correct do you know
