I've also just found a 5k pot (non-wirewound) and fitted it - results are much the same but with a bit more 'range' on the control. I've tried a few more sync seperator valves (ECC81's) as well but with no improvements.
Just to summarise!

The line hold appears to lock but the frame hold will not.
Very low volume and low gain, almost inaudible
Poor definition and an amount of sound-on-vision
Picture seems to white out constantly, adjusting brightness and contrast causes the picture to break up and be lost.

The photos show the best screen shots I can get so far, this needed very critical setting of the frame hold and fine tuner adjustment!

If anyone has any ideas on this I'd be more than grateful!!
