Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Good idea

The only thing I can think of right now is 2 SPDT switches. (cathode going straight ground or through the meter to ground)

If both are switches are engaged at the same time the meter would show the total current for both tubes.

Otherwise, just remember to only engage the meter switches one at a time.

I keep thinking there's a way to do this with one switch but I haven't thought of it yet.
