5F6-A Output transformer?

[spufuz]

Im "ivestigating" the possibilities of using an Hammond 1750L och 1760L output trafo in the 5F6-A circuit.
The reason is that i want to be able to use a 4 ohm cab with it.

But the 1750L and the 1760L is 4200ohm primary.
It seems that the 5F6-A wants a 4000ohm OT.

Would it cause me problems using the 4200ohm OT?

Second question, are Hammond transformers "good enough"?

The difference between 4000 ohms and 4200 ohms is not that big. Both amps (5F6-A and 6G6-A) use 5881 power tubes. The Hammond 1750L is actually a replacement for the 6G6-A Bassman.
Hammond is one of those "replacement transformer" manufacturers for older amps and the trannies are OK IMHO. I've used several with no issues yet.

Ok thank you!

My choises of transformers for the 5F6-A will be:
Hammond 1760L output transformer
Hammond 290DEX power transformer
Hammond 194B choke (4H, 90mA)

I can recommend Hammond (including the 1760L) and Mojo for transformers.
