Do you have SE:PP input transformer that suitable and improve to the attached differential MOSFET driver circuit diagram?
Follow Ups:
Yes, Lundahl has many transformers that are suitable for that application. Here are some part numbers:
"600ohm:600ohm"
LL1527, LL1527XL, LL1588, LL1684, LL7901, LL7902
"10K:10K"
LL1540, LL1544A, LL1545A, LL1592, LL1690, LL1948, LL1948Ag
Core materials, turns ratio, and size (maximum signal level) are the variables.

Hello!
Since my amplifier will have 8 pairs of MOSFET output device per channel, Can I replace all source resistors with your CCS? And how many I need? Which version of your current source would you recommend?
Thanks!
I can't readily answer the question you ask without circuit specifics. The Basic CS requires at least 12VDC across the current source and the cascode CS about 25VDC. Do your source resistors drop that much voltage?

I can have the power transformer made for higher voltage for the drop. But rumor has it that the CCS outperformed either with or without source resistors.
