McIntosh warns you about marring the finish on the receiver, but not about the 250 Volts running through it.

'Hold it across each of the large filters' :mental:

Sounds like the amp is transistorised so maybe the voltage isn't 250. Creating a big crack on discharge is more fun anyway.

(Don't try this at home folks if you don't know what's what) :)

It has a valve tuner. The transistors have 37V rails, but those caps have 250V to them. The valves are running at 120V. It's an interesting receiver. It has separate step down transformers for all of the different stages.

Sounds like you get some brilliant kit to have a play/tinker with.

It's cool. I'll take some pictures when I get some light in here. I traded 4 Pickering carts for it.

It might be fun but it's not good for the capacitors (or your screwdriver)!

I think we know that Will, but there is always a bit of a naughty side :eyebrows:

As for the screwdriver it rather pales into insignificance compared to the dumbo who used a big spanner to check if the bus bars down a South African gold mine were live :eek:

True story from many years ago, don't have recollection of any more details now.

It has some iron on it.

My Grandpa always used a giant screwdriver like it was a multimeter. Getting shocked never seemed to phase him either. I don't think I ever saw him use the right tool to do anything, but he always fixed everything.

I'm not in any hurry to get rid of that one. It sounds like a tube amp, and it has dual phono inputs.
