I see in yours a few of the red-and-black Plessey electrolytics; these are to transistors what the dreaded Hunts are to valve-radios: I've had more than one turn itself into a 100-Ohm resistor, which is not at all beneficial if it happens to be wired directly across the 9V battery supply, since it leads to customer complaints along the likes of "Why does my battery only last a few hours?".
Thanks G6Tanuki - I will treat this one as a 'rolling restoration'. I will use this set as my bathtime and holiday set but keep an eye on current draw going up and other signs of problems and replace as needed. My other early tranny sets will one day succumb to tin wiskeritus but are still ok - this one don't seem to have the AF117 transistor package.
