Home Tube DIY Asylum

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

Re: Tek curve tracer

I believe the 575 version with higher voltage was marked "mod 122".

There's a bit about it in Alan Douglas' book on tube testers and test equipment.

I don't believe it is a simple change - as I recall it involved changes to the switching circuit. I think Alan commented that it was easier to find a 575 with the mod already in place than attempt it yourself...
