Default Re: Ferranti TC1004. Baptism of fire.

Hi folks, after some time away, Iíve had a chance to put some hours in on my TC1004. A new LOPT holder has been constructed (see picture,) based upon pictures I found on a 2007 thread, (EKCO T311 LOPT).
The line/EHT side of the chassis seem to be basically working, I have a good line whistle and I can draw a good spark from the AC side of the EHT rectifier. There appears to be a 24 Ohm resistor connected across the EHT rectifier heaters that is not shown on the circuit diagram. Is that correct?
Thanks to PYE 405 I now have a CRT which I believe to be good (Thank you Andrew). The original tube has suffered damage to the base socket, and some of the wires are missing. The new tube however, needs a base socket fitted. The base on my old tube is too badly damaged to be of use (see picture) so Iím placing an ad in the Ďwantedí section.
The plan now is to work on getting the cabinet woodwork cleaned and repaired, and then to fit the new tube and go for Ďfirst lightí
Thatís it for now. Iíll post an update in a few weeks.
Dave
