This is a big metal thing in a 70s amp, does anyone recognise it?

Ignore me, it’s a flux capacitor

Looks like a mahoosive capacitor. 6800 micro Farads wouldn’t usually be that big though so dunno sorry.

It says Ducati in the thing so it must be a motorbike!

… yep I’d say it’s a capacitor too.

As said above, it wouldn’t normally be that big so might be made of some exotic material maybe because it gave different sound characteristic to a standard capacitor?

I think it’s just what a 1970s caoacitorlooks like

As above, a capacitor.

What sort of power is the amp supposed to put out, the better amps have a big transformer and capacitors to give more ‘headroom’ for greater dynamic range.
Chiefgrooveguru of this parish ought to know more.

If you reverse bias it with a lot more than 40v – it will fill the room with chicken feathers ( bitd vi form error 😉

It’s an electrolytic capacitor, or electrosplitic if you reverse polarity it.

Smoothing cap?

It’s a 100wattt bad boy so maybe that’s why the twin capacitors are ginormous
