Roberts R55/Amplion "Convette" LC4

[Nick]

There's a thread here about the Amplion: https://www.vintage-radio.net/forum/show...?p=1251314 I would want something with better regulated LT in view of the fragility of the heaters of battery valves.

Yep - saw that, but it's not the same model - I've posted "over there" too... RM hasn't got anything on the LC4 either, though it does have other Amplion "Convette" models... It's a nasty thing really - the inside of the metal case is rammed and has no earth etc. Bits of card are used to keep HT & LT mostly apart, electrolytics bulging...

I will almost certainly strip the innards of this one, keep the mains xfrmr, earth the case and replace the electronics with a modern, current-limited, linear version without PCB-filled caps and selenium rectifiers...

I can see that the LT on this model is centre-tapped full-wave rectified with CLC smoothing and the HT is half-wave CLC. I expect the electrolytics are completely shot and I dislike selenium plate rectifiers, so really not a lot left to keep!
