AES One Tube Transmitter

I'm thinking of buying the Antique Electronic Supply one tube
transmitter, but I need to swap the transformer over for one that
handles 240 volt, gives out 125 volts. Can anyone tell me of any
Australian online sources for this?

** Far easier to buy a small 240 /120 stepdown from Dick Smith ( cat:
M1155)

Mains transformers like that one were obsolete over 40 years ago.

I was looking at that stepdown convertor. Should I power it directly
from that, and remove the old transformer, I've been told it's an
isolation transformer. Since the transmitter's designed to be
installed on a wood base high voltage exposed, it would need one. But
I'm gonna install it in a plastic box for safety reasons (with two
very inquisitive cats, we can't have exposed high voltage like that.)

** Don't be so fucking stupid.

You need 125 volts AC for HT and a *separate* 12 volts AC for the tube's
heater supply .

Isn't it unsafe to use a 60Hz transformer on 50Hz? I've been told
several times it is, unless that transformer is designed for both
frequencies. Guess I can always try it to find out.
