Roberts R66

[LyntonP]

More work on the Roberts today. Changed the LT selenium rectifier for two diodes and brought the mains voltage up slowly using a variac whilst monitoring the LT. Ended up with a couple of resistors in series to achieve a LT of 1.39 volts. I now know the total amount of resistance I need so the plan is replace R15 and 16 in order to achieve the correct voltage. I will have to order some low value resistors. Domestic duties over the next few days but I hope to make a battery for the AVO over the weekend.
Again thanks for all the help
