question for those outside the US concerning use of US wired amps

Here's the question - (not that I'm world travelling anytime soon)
but would anyone know if I did take (for example) my Deluxe Reverb
outside of US - are there easy to use plugin 'converters' so that
I can still use my amp? Or do I need to have transformer changes
or mod the amp somehow ? (It's standard US 120 volt AC).
That would go for all the amps I have (120 volt AC).

I know they have some trick connectors/converters for appliances
and such - but not sure if these would actually work properly for an amp.
I'd hate to fry it and then be really sorry for doing it wrong.

I know once it gets to the rectifier it's all DC current from there
so it's just getting regulated AC at right voltage into the amp to begin with (?)

ok - any comments or personal experience appreciated (or pointers to
gadgets/converters that are known to be ok with tube amps).

Can't help much, but I do know that direct US imports to Oz require either a
step-down transformer or a replacement power transformer. This is the first
thing that came up on Google as a sponsored link:

http :// tortech,com .au/index8.html

I've no idea whether the frequency difference has any significance for an
amp, I would guess not.

Yes, not all parts of the world have the same line voltage. Europe for
example is around 240v so yes a step transformer would be needed or you
would need to mod your amp with a transformer designed for different
voltages.

Re: question for those outside the US concerning use of US wired amps

just a thought but i think most european cars have 12 volt dc batterys. so
why wouldn't a heavy duty battery charger that plugs into there power hooked
to an inverter for north american power work. just a thought.

Inverters can be noisy. The whole setup would be inefficient. Better to buy a
good step down with proper ground assignment.

Re: question for those outside the US concerning use of US wired amps

good inverters have filters. if i'm not mistaken it would take more than a
step down transformer. european power used to be a different h.z or cycles
than ameracian wich is 60 hz. they used to have 40 hz. what is it now?

Agreed. The battery would be toast in no time.

i guess you didn't get it. iwas saying a big charger. one that can be used
to boost. no battery involved.

I have a US Fender amp and I use an external transformer between it
and the local (Australian) power outlet.

You couls have the amp modified, but I chose against that.

There are often preamps etc. sold here that come with a converter from
US to european power..but I dunno if they would be powerful enough for
power amps...

I've had my Super Reverb (American) in Europe, and there was no problem
using it with the appropriate transformers.

On some Fender and other amps (not sure about the more modern ones) the
operating voltage can be changed by moving a clearly labelled plug/switch
which changes where the power transformer is tapped. On other stuff (the
Alembic preamp comes to mind) it's simply a matter of opening 'er up and
moving a lead from one lug to another one on the tranny. Easy-peasy if
you know a bit about electronics.

Otherwise, an appropriate external transformer is easily found in yer
local electronic store.

Just make sure you get the correct power rating. i.e. Power CONSUMPTION
not power OUTPUT. A 100 watt amp could easily have a consumption of over
150 watts or more.

Yes, this is true - although I've never seen one intact - generally
(smart thinking) techs remove these switches/fix them down somewhere
inside the amp so they can't be fucked around with.

Which is all in all a sensible practice. I can just imagine how pissed
off I'd be if I plugged the thing in at a gig to find that the switch
had been bumped from 230 to 117....
