My friend was a wining bidder on a guitar amp, it was posted as not
working, stating that it blows the fuse instantly. So he
knew that it was broke from the start, didn't pay much for it.
THe seller even removed the shipping cost ($25) to be nice..

How ever, he asked me to look at it for him to see if it can be
repaired. I don't know much about the cost of this type of equipment
these days since I really don't buy it how ever, he stated it goes
for $400 bucks new..

Any ways, I opened it up, noticed that it had already been looked
at, cause some one was nice enough to mark the secondary xformer leads
color on the circuit board. So I guess it's been unplugged from the
board before I got there.
I finally ended up doing the same to remove any doubt of shorts that
could effect the loading that was taking place. As it turns out, even
with all the secondaries disconnected, the xformer still loads up heavy..
This unit only extracts no more than 250 watts max from the line
(2.5) amp fuse when working properly!

After performing some test on the primary of the xformer, I come up
with Lx = 1.5 (4 mh) and 3.5 dc ohms..
Z = ~3.8 ohms. which = ~ 31 amperes at 120 volts, 60hz..
I guess this would stand the reason why it blows out a 2.5 amp fuse

When all said and done, I think this defect was already known about
since the primary had already been disconnected and most likely a load
test was performed to verify a bad xformer..

Ok, just thought I would pass that along if any one was interested.
