RR763 Blackvibe 6L6 output transformer compatibility

[jackson649]

Hi, needs some help and hoping people can help. Looking to do a 6L6 black vibe build. i have a 125A29A transformer instead of the 125a7a thats on the layout. Will this be usable? or will i need to change parts from the layout as designed?

The 125A29A transformer is meant for a 4 x 6L6 amp.

I built the front end of this into a recent pre-amp build. Phenomenal circuit.
