Fergus OMore:
For two quid at a fair some years back, I bought Telequipment Serviscope Minor that 'lights up' has wiggly green lines. Needs another probe( my limit of present skill) so can I get instructions that a near idiot could understand or should I dump it please?

Hopefully, I haven't pee'd on your parade.

Regards

Norman

after a quick web search - http://www.thevalvepage.com/testeq/telequip/servmin/servmin.htm

its a bit older than the scopes I was thinking of

found some service info

after looking at fleabay   I'd say don't dump it straight away
you could find someone  daft enough to pay a lot more money  than I expected

is this the info you are looking for ?

Gosh John, you are doing well, having been born in 1667!  Seriously, thank you for taking time to help me

Hi Norman

no problem , I help when I can

I nearly was named Johnathan
I'm not that old, I'm only in my 60's but this last few weeks have felt a lot older

as a result of an old injury
I have sciatica from time to time  that make simple tasks like putting on socks a half hour ordeal
you have to keep moving and do what you can , when you can
