Re: Eddystone S640. Mains primary open circuit.
To finish off the thread.
I changed all the usual paper caps. The main two smothing electrolytics were re-stufed and the rest replaced. Quite a few resistors had to be changed. 3 of the valves were changed as the metallic coating had come off. The only problems other than the mains transformer, were intemitant toggle switches and a broken slug. To aid allignment, I made up a temporary plate to replace the origional R.F. shield. This plate had 9 extra holes for the coil adjustments. The origional plate only had holes for the trimmers which seemed strange. The set is now working well. Thanks to the Eddystone user group, who helped with some of my questions. Colin
