... Buy one of hevier one(bigger size and really heavier in
weight than stock) If it blows again, something on the load side is wrong.

I'd venture something is already wrong...

I'd agree. Responding to his first post and before he put this
latest transformer in I recommended measuring
how many amps are being drawn on the low voltage side.
This is electricity 101. So, he comes here asking for advice
and instead of listening, he justs puts another transformer in
and blows it too..... Go figure. Time to either get educated
or hire a pro.

In case you hadn't noticed, I've been getting LOTS of (much appreciated) advice
from many people, but it's also been very contradictory with no single
suggested approach. It's been an interesting and informative discussion, and
I've been happy that nobody's been a jerk about it... until *now*. And I DID
listen; plenty of people suggested that the original transformer was likely to
be under-rated and to replace it with something more heavy-duty. Also, it
seems to me that having a working transformer is a pre-requisite to following
your advice of measuring the amp draw on the low voltage side, no?
Unfortunately, time constraints prevented me from being there to perform those
measurements when the unit was running, and unfortunately again the transformer
blew in my absence. But of course, I'm repeating myself...
