One more question -- when the alignment instructions say to connect the "high side" of the signal generator lead to the #6 pin of the 7A8 tube and the "low side" to the B- -- what does that mean -- the high and low side? My signal generator has a coaxial cable connect to the Radio frequency output. The center of the cable wire has an alligator clip connected to it and the other thing would be the shielding of the coaxial cable seems to be a like a ground - is that the low side?? Thanks
