If your speaker contains the transformer:
1. If you graft the transformer to the new speaker (the FC is OK, 10% difference is not very critical) it will result in 3 times the impedance and your output performance will be degraded quite a bit.
2. If however the speaker has its own transformer AND it was made to work with a 42 tube output (or a tube with the similar requirements for a load impedance) then the VC impedance no longer is important.
If your transformer is separate, then you are going to have same #1 problem. I think in the 45 it is separate and is installed on the chassis.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
