Then I remembered that I'll be powering the TV using the wall outlets of 124vac. I had to go up to 15 ohms to get about 132V B+ voltage.

Thanks.

Your line voltage is quite high! Ours is usually around 121 volts. The distribution transformer is on the lot next to me. A newer area, 15 years old. I imagine, the voltage is that high to avoid brown-outs in the summer time when everyone has their AC on. Your warm season is a lot longer than ours.
It's great to see that everything is working out fine. A lot of effort was put in and the results show it!
