Default Re: Shaftesbury 519 amplifier

I'd be suspicious about the Hunts capacitors and any of those Plessey red-yellow-black electrolytics too. The resistors can be checked (many of them whilst still in circuit) and replaced if well out of tolerance. If appearances matter you could paint the usual yellow polyprop capacitors black though disguising modern electrolytics might be harder. I've not heard of Plesseys being restuffed but it might be possible. If you search hard, you may be able to find hi-stab resistors of the same construction (extra salmon pink band) which are normally well within their specs even 60 odd years on.

Only you can make the value judgement about repair, restore or preserve- it's yours to do with as you wish after all.

Circuit- can't help, though a single ended EL84 amp even with tremelo shouldn't be too hard to reverse engineer. Using a similar Fender or the like as a starting point could make it a bit easier.
