Hello
I am new to the forum.
I am a proud owner of a L3-3 tube tester and before switching it on I would like to check all the Caps are in good condition.
Once I have done this I was wondering if it would be sensible using an Isolation Transformer with the unit (possibly while overhauling it).
My question is how many amp Isolation Transformer would I need to this.
Thanks in advance.
Brian
