The Philips 206A Trader sheet 478 lists the radio as released in 1940. I wonder if the capacitor is a replacement, or the radio had a long manufacturing run (not so likely).
Well of course that is possible. Unfortunately the original reservoir cap has been removed so I can't check that one. I suppose it's possible that none were made during the war and then production started again afterwards so a production run into 1947 could be feasible....
Anyway I've taken the chassis out and had an initial look around. Most of the rubber wiring will definitely need to be replaced, all the hunts waxy caps and the Philips tar 'road blocks' will need replacing so plenty of work required. Some of the caps are buried beneath others so some dismantling will be required to get at them...all good fun. There has been some poor soldering carried out but most of that will be sorted when the caps are replaced. The plus points are that the mains and output trannys' check out OK resistance wise at least.
So when I start on the set, I'll begin with the mains transformer rewire and go from there.
There are some pictures of the set as it is at the moment. I noticed that there were tin whiskers growing on the back of the tuning drum. I immediately thought of the AF117 scenario. Must be the same processes going on.
