Output transformer for 6GW8 pp amp

[jamesedmunda]

I need an output transformer for a Guild Thunder Reverb that uses 2 6GW8 tubes.
I have a Hammond 125 universal ot does 10k seem right for the impedance.
TIA James

I have a 8K in my PP 6GW8 amp.

What did the guys selling this tube say?

Page 4 suggests 8k at 250V, 9k at 300v.
10k is certainly in the ballpark.
