choke question

[ernie_jr]

I have an old UTC choke 200ma 20 henries.
Is 20 henries to large to use for a bass amp?
I know most are around 5 or less.
thanks,
Ernie

The only thing "too big" about it is that at 20H and 200mA, it is probably big and heavy.

No problem using it with a bass amp. It would be really nice to save such an item for a choke-input supply on say, a 2x 6L6 class A amp.

thanks,
it is big, almost as big as the O/P tranny that was with it. it came off and old williamson w/ 807's amp that i inherited several years ago.

Yep, perfect application. The Williamson had a choke-input power supply, and that 20H 200mA choke carried the current of the whole amp.

It's a shame to use it any other way, really, because it would likely be under-utilized.

Might be useful in something like the 5E6 Bassman that has the choke upstream of the plate node.

was thinking of using in UL mode a la SUNN
