Default New Member from the Netherlands,

Hi, I'd like to introduce myself, im 22 from the Netherlands.

My interests include measurement equiptment, electron tubes (Been hobbying with the thermeonic Fets since i was about 16) I built multiple homebrew valve testers to my own designs.

Anyway the reason for signing up to this forum is that due to the fact that the Sussex valve tester has become rather popular on this forum, and most of the Dutch language forums the interest in these projects is quite limited.

Hi and welcome; as far as I know there have been at least 90 Sussex's built by the number of transformers supplied, and there have been many more queries.
I look forward to seeing some of your postings on your testers.
Have you built any curve tracers?

Hello and welcome to the forum. Nice to have some one young that is interested in the vintage electronics that use proper wire connections, rather than the Bluetooth tech.

Personally i like point to point wiring with ceramic standoffs(The tektronix way) however given that professional looking PCB's can be outsourced to China for less then the materials to needed to etch them yourself, the future of homebrew could be in computer aided design.

I have not built curve tracers, i consider them novelties because they are not tube testers, most of the time the dissipation is inadequate to find issues in output valves. I have an old Philips curve tracer that needs some TLC.

A good homebrew tester is all about a very stable grid supply, and perhaps higher resolution then the 2000 count panel meters will offer.

My last project was a prototype supply, that can regulate between 0 and -100V and allows the measurement of grid current on a 200uA scale.

I will devote a post to some of my ideas.
