Hi everyone.

I have an Astor Transistor Mantle radio model M6D, from around 1972.

Unfortunately its mains transformer is kaput.
The primary is 240volts, and its secondary winding is 40volts, centre tapped at 20 volts. It is quite small and only needs a secondary current of about 75mA. The transformer, made by Astor is 61mm wide, 37.5mm high, and 33mm deep.

I am desperate. I will shoehorn anything short of a transformer designed for a guitar amp into the case.
By the way, the cabinet is designed to attach to a wall as well as to sit on a bench top.

I have several Arlec model 2155A transformers, brand new and you are welcome to one.
They have a multi tapped secondary up to 15V and are similar size to yours.
I'm no expert, but would this be a candidate to strip out the secondary winding and rewind a 20 - 0 - 20 secondary?

I have the correct transformer, must be a coincidence as handled it today as part of wrecked chassis, after many, many years.
Primary leads to transformer have been cut short, but will present no problem.
You can have it provided its picked up with some other free radio stuff from Tassie.
Otherwise cost of postage for transformer only.

Thanks Harold for your kind offer.

Jonny from Tassie has miraculously found the correct transformer.

Thanks again.
