Thanks for the thread Mark. I've got one of these-donated by a Form member about a decade ago. Cosmetically pretty nice [although the speaker cloth is not as good as yours of course
]. It's mainly been a display item but a quick check last night indicated it's gone a bit buzzy, the tuning mechanism is a little wonky and there is a tendency towards overheating so I will keep an eye on "that" transformer [having been pre-warned by Kalee20 and yourself]. Anyway, I've now got a restorers guide to hand as and when I get round2it
Cheers,
Dave
