Default Re: Baird T5 restoration project.

The T5 power supply unit was tested on the work bench today. All the original TMC electrolytic capacitors have been refitted so the unit has the appearance as how it was in 1947 when the set was overhauled by the service department of the successor of Baird Television Ltd.

The Variac was used to bring the mains supply up in a cautious manner which is just as well as the HT voltage off load is almost 450 volts, the same as the maximum working voltage of the new capacitors.

HKS has informed that TMC stands for the Telephone Manufacturing Company.

Tomorrow, the power supply unit will be tested in the T23.
