Info on tube testers
Through the years I gathered quit some information/pictures/etc. on tube testers (about 11.6 GB). This morning I uploaded all to Google Drive.

Almost all comes from the internet so don't expect 'new discoveries'. But maybe it is handy to have it all at just one place.

The link: Tube Testers - Google Drive

I don't seem to be able to download seperate files from there yet (something to do with cookies?) but I do manage to download folders from it.

Thank you very much for consolidating that info. I have a TV-10 and a TV-2 and I grabbed all the info on those. I might already have it, but I surely do now.

Thank you from a TV-7 owner :up:

You are welcome. I'm happy to see it is of use.

I recently fell out of love with my tube tester when it claimed a 12AX7 was good when in reality it was not. I wasted a couple hours thinking the tubes were good.

As of campsquire problems, some tube testers do soin a vfery basic way, and not under real world conditions.

Like Enzo says: "a tube tester can tell you itīs BAD, not really that itīs GOOD"
