Since my last post I've replaced VT2 with an AF127, but the set is still unstable. I now have the GT322A Transistors, so will replace VT's 1 & 3 with two of those. There are also a couple more electrolytic caps. to change, and I've also found the circuit diagram on Radiomuseum.org, and since then discovered that it's also available from Paul Stenning, but is listed there as 'Playmate 800T', rather than 'Wolrd Radio Playmate 800T', which is how I expected it to be catalogued, WR being the maker's name. It's a fairly standard 7-transistor radio with single tuned IFTs and a push-pull output stage, but has seperate switched aerial coils brought into circuit to replace the ferrite rod aerial when the 'Car' button is pressed.
