There are so many driver chips available, from the venerable SN74141s and
Russian equivalents through the 4017s, 595s SUpertex chips etc.
What are people's favourite driver chips (clockable, serial driven) ?

Firstly, I only do direct-drive.
I dont use driver chips. Instead, I use either NPN or NMOS discrete
devices, because I can ensure constant-current thru the cathode.
Using a dropping-resistor will result in some current-variation due to the
tube's characteristics, or supply voltage variation.
Hi folks,
At our last local dorkbot-meeting I got a fully working digital multimeter
with nixie tubes as display.
It's a Takeda Riken TR6155M and calibration still seems to be OK.
After cleaning up the front panel it looks like new :-)
Does anybody have technical details, service manual or any
Roger,
Congratulations on the test equipment find.
Good luck finding data for that unit. It's hard enough to find manuals
for the common-as-dirt Fluke Nixie voltmeters.
I have a cheesy, c.1972 Leader incandescent 7-segment display voltmeter
that turned up at the local surplus place. It
