Home Tube DIY Asylum

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

RE: Use a reversed filament tranny.

This cracks me UP.

When I built my First VTVM in the 60s, I wanted to check the HV scale. I think it was 1500vac max.
So, I hooked up 4 or 5 transformers BACKWARDS. I think I had bell transformers.
It even worked for a SECOND or 2 until the last transformer or 2 SMOKED. I suspect HV breakdown of the insulation? But what do or DID I know?
And the awful Aroma of the SMOKE. I had to open up every window I could get to and try to air
the house out. I'm sure it was TOXIC as hell.

Meter DID kick up to maybe 3/4 scale before meltdown.


Too much is never enough
