50A of heater current!

EDIT:

Oh, I have read that this person's next project is a copy of a Tektronix TEK570 curve tracer, and is looking for several valves and offering Siemens rotary switches in exchange.

I've always wanted a nixie clock, but I've never seen them for sale in the UK apart from odd pairs on Ebay. Oh, and valves scare me...

Nixie clocks

I made one in '68 when TTL was new! The only tubes are the 6 nixies and a glass tubed 1MHz crystal.
I think I still have it amongst my junk. Must sort it out and "oil it". Will post a pic.

pm, tubes are harmless as long as you don´t smash them

Indeed a beauty it is !

mmmmmm...... but isn't it a waste of tubes to ?

Imagine howmany preamps you can make with this amount
