Need EL34 grounded-grid curves

Hello gentlemen,
I've not been able to find EL34 curves for cathode-driven operation
anywhere. Help would be greatly appreciated!
The grounded grid curves are the same as for grounded cathode in either
pentode, UL or triode.
Voltage gains are indentical.
All that changes is the input impedance which is high for grounded
cathode, and very low for
grounded grid, and Rk in = RL / voltage gain.
There are no separtae groups of curves for grounded grid.
Musicman guitar amps used transistors to drive the cathodes of output
tubes,
and this could have been a reason why they went out of business.
