Interstage transformer GM70 amplifier

Welcome! Need support, you got it. Or share youe ideas and experiences.

Hello!
This is an integrated amp for 845 but want to have GM70 instead, and intend to convert to standalone amplifier by replacing with higher step down ratio interstage transformer rather than 2:1 as the circuit recommended (so the GM70 will see much lower impedance from the driver section). Do you have anything for this application?

Also, we will change the output stage to parallel feed with LL9202AM OPT, any plate choke can you prefer?

Thanks!
