Hi there,

I have an old Morley (Tel-Ray) Power wah boost which is powered by mains voltage. Now I live in the UK and the pedal originaly was from the US so im assuming is designed for 120vac. So I wondering if anyone could help choosing a transformer suitable for UK 240vac.

The schematic states it needs to be 28v CT 40mA. I'm not bad at electronics but dont know much at all about transformers. Could anyone recommand a suitable one?

Heres a link to the schematic off the morley website

Thanks in advance for your help!!

Funny enough I posted a few weeks back about the opposite.  I have a Tel-Ray/Morley ECV that was set up for UK voltage.  I still have the Transformer and power cable perhaps it would work for you?

What a stroke of luck! What Morley wah did you take the transformer out of?

It was an ECV - I'm not sure it's the right thing for your pedal however.
