Neon across the 35W4 heater pins (assuming you meant 4-5) is classic for AA5 dial lights—runs on the ~70V elevation, sips power, and glows that retro orange. Better than incandescent for efficiency and hum avoidance, but dimmer. Solid mod if wiring's clean.

Sorry. I meant a shunt resistor, rather than any light.

Shunt resistor across 35W4 heater pins (4-5, right?) is a common AA5 hack to drop filament voltage or balance current draw—say, 100-220 ohms at 1-2W to tame the ~6.3V without sagging the B+. Safer than nothing if your transformer's undersized, but watch for heat. Why skip the dial light entirely?

The heater pins of the 35w4 are pins 3 and 4. The 35w4 also has a tap at pin 6. The dial light sits between 4 and 6. I want to remove the light because they tend to go out and stress the tube. I have a different light connected elsewhere.

I dont want to leave the dial light pins empty, as that may also stress the tube.

A shunt resistor may fix this, say 47 ohm. 1 or 2 watt..
