/diy/ - Do It Yourself

>>1061457
I made a dummyload to aid testing.
you might spot the variac behind the meter, used for safer testing.
not in frame is a 6amp automatic fusebox that runs the whole bench.
I use this to switch the whole thing on and off, avoing to fiddle too much with it while its running.

any tube guys got any tips for scoping the interstage signals without blowing my scope?

I was thinking a 1/100 resistor divider with zenerdiodes in antiseries camping down the voltage on the scopeside to 10.1v

afaik, my scope is grounded.
making tripplesure that i connect ground to ground should be save enough.
does anyone groundlift their scopes just to be sure?
We did it a few times at my old just as a maritime service tech, but it was never really necessary
