Transformer Primary Wires ?

[Barry]

It is AC, so why would it matter?

Precisely!

Thanks Barry, getting close now. Just got to find 3 7025 valves.

Hi

I've finished it (thanks to your help on here).
Very pleased with the sound but I have a dreaded hum now with this Phono Stage, my previous one was quiet (Edwards Audio MM1).
Any ideas ?
Nothing has changed apart from the phono stage.

Is the transformer shielded?
Is it close to the phono stage circuit?

I believe opinion is divided on the issue. I'm not going to say more than that as I've never tried swapping polarity.

[CageyH]

Polarity swaps 50 times a second.

Hi Kevin

Turned I'd put the ac wires too close to the signal wires.

Glad to hear the problem is now sorted. Well done!
