Thanks for that. The light suddenly came on and it nearly blinded me. I should read on tubes some more.

I have run a simulation of the circuit with MOSFETs in place of the tubes. It works, but the output is only 5Vpp, so some more work is needed. Since the OP has reacted yet, I will leave it on the back burner.

SS phase splitters?
Good morning,
I'd like to try the above circuit. Any guesses on how much swing? I'm building a sweep tube amp that will probably have 40-45v of bias.

Thanks,
Ray

Thanks for the input so far,

Great ideas and circuits.

I was wondering how easy/hard it would be to implement, (reduce space) with some of the more complex splitters. Nice to see other examples.
Theoretically I guess you could build a whole tube circuit with FETS I wonder if anyone ever has and what it sounded like (Off topic) FET with OP Tx.
Back to phase splitters the small 6V6 is interesting.

Regards
M. Gregg

Those days i have presented a new type of phase splitter. There are also version specified for tube circuits.

Have a look at this thread:

wow, a wimpy BS107

btw, would a simple SS 'phase splitter' handle multiple parallel output tubes better than if a tube

The Velleman K4000 comes to mind with a 12AX7 in concertina driving 4 EL34 per channel. You may have a point!

not so sure
driving capacitance also seems problematic with solid state designs
maybe its all the same, a Murphy's Law

anyway, what is the reasoning for using solid state devices ?

gosh ! I only know the difference of tubes and SS by the looks
