Zenith Phonograph Conversion

[Blindog]

I converted an old Zenith phonograph to a 5E3 Tweed Deluxe circuit. After rmuch tweaking I have it sounding pretty good, IMHO. I only used one half of the 12AY7 (1 volume, 1 tone, 1 input jack) My question is how to utilize the other half of the 12AY7 to get the interaction that occurs on the real deal without having to add all the other components. Is it possible?

Thanks!
