Perhaps you can post a link to the Ebay sellers page?

I checked the Douk Ebay shop and could not see it.

No. 251742471806.

That's the 1, thank you slinger.

I've just put some new boards in. Based on musical fidelity a1000 amp. My heathsinks are 1kg, they are very hot.

The boards don't say there class a, but have 4 transistors each board.

We will see what happens.

You won't need to put the heating on.

If thats all that happens, I will be very pleased.

The ones doc gave me weigh 1.8 kg and have larger fins. Once I had broke the seal of thermal paste on the old heatsink, I reglued them on the new heat sink and waited.

They get hot, but much, much better.

Deos anybody know why my phono amp only works for 10 seconds when I unplug it. If I then plug it in again, it geos silent. Only to work for 10 secs or so when I unplug it.

Its a modified phono 1. Transformer, rectifier and caps are in a seperate box, joined by cable. I recently put the transformer et al in a metal box instead of perspex. It hasn't worked since.

What have I done?

Looks like a cable fault. Check the mains wiring first.
