Tube Question

I have the m125's with 8 Genalex Output tubes using a Mullard rectifier tube.
Is this ok or should I be using the Weber SS.

Also I have the Mullard M8136 in the front position and the GE 12BH7A in the second position...is this combo ok?
If not should I go for four of the same?

Thank you,
Frank

Which Mullard rectifier?

MULLARD GZ33

Did some research...my m125's for the rectifier sockets were wired with the DIODE MOD. Also my 803d2's are 90db efficient..so I feel a bit better since reading that the Genalex KT88's Output tubes can put a strain on the rectifier tubes.

Thanks for responding and feel free to add.
