i think i will try and sort the money to get one shipped over to the
uk (PSU). once that is safely here then i will look at 'tinkering'
with the broken one.i dont yet have the confidence to go messing with
one of theese, i had a stroke last year so fine work is still
difficult! thanks for all the help i will keep you posted on progress!
great to know there are still some spare parts about.
while i have the covers off i will take the leads of etc and give all
the contacts a clean as there is a fair but of gunge in the machine
not to mention more than a few spiders in webs!!
managed to contact the guy i got it off and he wasnt much help, also
mentioned to me that the hard drive is probally shot!! but having read
the messages on here when i get the power back i might look at putting
a cf card in :D.any other spares i should be on the look out for?
one last thing if i may.. where is the best place to get a isolating
transformer from?
kind regards jason

Cheapest isolation transformer is free, if you can scrounge well. Find
two old tube-type TV sets, with power transformers.
Take out the transformers, and connect them back-to-back, using the
high-voltage windings on each. Take the 120V winding on one
for the line connection, and the 120V winding on the other for your
isolated output. If the voltages don't match too well, you
can use the filament windings on each one, in aiding or bucking,
connected to either the line side or the HV side, as required,
to get the in/out ratio to be 1:1. (Where I said 120V, if you're in
Europe, substitute 240V, or whatever you use there.)
Do not connect the ground pin of the female output jack to anything, so
as to maintain isolation.
