Poseidon board in M125 mono amps

Hi!

I love the tubezone mod Poseidon boards in my Dynaco Mk iii amps and am wondering if anyone has tried them in the Latino M125 mono amps? Is there a problem driving an extra pair of tubes. If I go this route I was thinking of modding the bias circuit as per this thread but duplicate the bias/bal stages for the extra pair of tubes:

On the Poseidon board C4/C5 to R12/R13 would be duplicated for the extra pair of KT88's.

On the CVD PS board D1 to C12 would be duplicated.

Forgot to mention the Latino transformers are copies of the Dynaco transformers as shown on pg 5 of 8 of the Dynaco transformer catalogue. The originals are Dynaco #'s A-451 for the OPT and the PT is PC-706.
Thanks,

Tom
