hello friends,
I have restorated the second triple nickel.
Have fun to see some pictures from this glowing wonder,
http://www.wellenkino.de/555Plugged with 2 dual trace plugins CA there are 117 tubes glowing, eating 1kW.
This scope have a scope mobile and external PSU.
I have worked like in the old time, with an tube voltmeter + HV probe.
greetings from germany
