A music playing test sort of worked, :/
but did not play very loudly, no surprise, as in order to keep B+ bias down, I have the input voltage quite low, and so the heaters are hardly getting 5 volts and so the 12AX7 is hardly lit.
I'm guessing it will get better once I get the resistors for the voltage divider and get things a bit more stable.
Using a modded version of this,

Will just have to play with it to get the voltage correct.
One thing noticed, the 6V6GT gets DAMN HOT :O, which, from what I have looked up is apparently normal for it.
All in all, once complete, and all the tweaking is done, this thing should fit in nicely in the Jensen speaker compartment in what ever is the final enclosure of this TV.
