Default Portadyne record player intermittent.

Hi I have a Portadyne player which is causing me grief. I'm not an electrician of any sort but I can do basic things like look at the valves, take them out and replace etc. It gave me a bit of a sting after I disconnected electric.

My sound problem is intermittent it comes on then fades out, or vice versa.

As I had the back of it, and replaced it, a small tap down seems to correct it for a short while, so I'm assuming it's a wiring problem rather than anything else.

If anyone can help I'd also be grateful!

This could be oxidised valve pins. The chassis in this is liable to be live. Disconnect the mains, wait a bit, carefully remove the (2 valves) without bending them, clean the pins with emery cloth/sand paper, reinsert, power up and try agan.

Many thanks Edward it does seem easy to disassemble, have had her apart once, will look at this tonight. I thought it would be dirty or dry solder but I'll give this a whirl Cheers!!
