Title: Message
Actually I would like to know the difference
too...
I
just
know that the site trannies are supposed to be safer and are a hell of a
lot
meatier and cheaper (by capacity)...

Doh! I must have been asleep when I wrote the original
message.
It's
a Sonance amp (lime my speakers). The other amps I have are
parasound.
Although it would seem the AUTO TRANSFORMER is the problem (still
awaiting an explaination of this!!!), maybe knowing the details of this
will
help explain the problems too...
cheers,
Tony
What is the power rating ?
Physically how big is it ?
By
the sounds of what you describe it is just an adapter with a Diode in
series
which will not reduce the voltage but give power for 50% of the time. Some
appliances (notable heater type things like Irons) would be OK with this
but
anything with a transformer will complain bitterly as you describe.
WORSE STILL.... the transformer core will become saturated and cease
to be an inductor, at which point there is nothing to limit the rise of
current and it can self destruct :-(
You need to supply more info but until then ....DONT USE
IT.

Peeps,
I bought a parasound audio amp
>from
a suitable converter (from craplin I think it was) - a two
socket
cylinder jobbie, which has a higher power rating than the usual
wall wart
type step down transformers I use.
Anyway, the amp buzzes
rather annoyingly when plugged in & I don't know if
it's the amp or
the step down converter causing the problem.
I don't have any other
110v amps to try with the transformer, though I did
use my audiotron
& had no problems with that.
Also, I don't want to try my other
transformers with the amp as they do not
have a high enough power
rating - also, I think they might only support the
two identical pin
type connectors rather than the one larger than the
other
type....
I know it's a bit vague, but any ideas how I can
identify what the problem
might
be?
cheers,
Tony
