** Is anyone here unfortunate enough to have experience servicing Fender
Passports ?

In particular, the Passport PD250.

All of them are horrible (Chinese made) things, but this one has a trap
for
first timers.

The SMPS will not start if you use a variac to ramp up the AC supply.

So, if you are told that a unit does not operate and do the usual bench
test
with a variac first - the story seems confirmed.

Big mistake.

Fender Passports are on my "don't even bother looking" list along with
Mark
Bass power amps.
Horrible heaps of junk.

I've repaired 3 Mark Bass, that have not bounced back . At least from a
combined effort on this board a while back , we now know the workable
identity of the ground-off PS supervisors as being IR2153 or pinning
equivalent. I'd prefer Mark Bass to Yamaha StagePas as at least a bit more
space to play around in.





You're a better (and more persistant) man than I am Gunga Cook.

I can't be arsed faffing for hours with that kind of stuff.
