I want to power it up with batteries to try it out. It uses 9V for the "A" and 90V for the "B" battery - just like a T/O.
The battery connector has three wires, which are black, green and red. The logical guess is that black is common-, green is 9V A+, and red is 90V B+. However, I don't want to leave that to chance.
Also, it does use the "unobtainium" 1L6 tube. I would like to try it out with a 1R5, which is known to be a "safe" sub on the AM BCB when one wants to try our a T/O. Would a 1R5 also be safe in the GSL-1079A?

I'll look at my Sams library to see if I have it.
The radio is made by Sonora for Wards, circa 1954/55. I still have one somewhere. I even had one with the Sonora branding.
Regarding to 1R5 sub, it didn't work in some sets, as there is two common pins on a 1R5, that the 1L6 doesn't???? Someone stated that, ages ago,I never tried it. They stated that you had to clip that pin off the tube.
