[Mr Grumpy]

Hello phellow Philco phreaks,

It's been a while since I've posted anything, my 3 year old has been keeping me plenty busy.

I had a quick question about Isolation transformers...
Up until now, I've been replacing caps and resistors, testing tubes and getting rather lucky. I'd like to start doing some real testing on some of my problem sets but want to buy an Isolation transformer first.

I've notice the ones linked below but I'm not sure if they'd be right for radio repair. Does there have to be a minimum output from these? Anything in particular I should be looking for?
P.S. - I don't want to spend a fortune.

Thanks.
