Tube synth diy

Thank you  Andrew for your suggestion, that was what i thought first, 
but a little different... look at the schematic.
When i say a "tune control" i mean a kind of "pitch" or "randomness 
selector" as they called it...
Secondly, What do you think about the best way to add a second output?
my problem is how will i be abble to plug or unplug one of the two 
output without any variation on the outpu level still plugged.
thank you
Jon
I will add some of the books i told with 50's/60's circuits
