Hello again. Well after having my usual moan about various things i decided last night to try putting some power through the set. and after a little while the heaters lit up and a distinctive whine came from the lopt to reveal the PY81 was useless 
. so in went another valve and again after a while it came up but i could see nowt on the screen. so after a bit more tinkering i twiddle the brightness control and i get a nice inch high strip across the screen,thats right frame collapse. so for a set i thought would be more trouble than it was worth has turned out to be a good prospect. cheers neil.
That's a result Neil, give us some pictures.
Chris
