In other news, I've ordered these Jantzen caps, for the Celestions, to replace the original electrolytics: https://www.hificollective.co.uk/com...apacitors.html

They were the only 'sanely priced' ones I could find in 12uF, and cheap as chips! Should do the job nicely, in combination with the Jupiter Copper Foils

I've also ordered some of this Jantzen speaker cable, to rewire the internals [nothing fancy, but it'll do the job and be a million times better than what's in there now]: https://www.hificollective.co.uk/cat...e-2x13awg.html

Full report on the results when both have been fitted!

Marco.
