Not sure what kind of thyratrons you're working on, but for most of us a 100mA or 1A current limiting would make more sense.

Reverse engineering the circuit is the only way I can think of to figure out the replacement resistor value. But if you happen to have a big wire-wound rheostat lying about you could sub it in. That top band looks black, and the bottom one is probably brown, which is a problem because black doesn't make sense as a tolerance (nor as a first digit). Pic related could arguably help, but it's a 4-band resistor so I doubt it.

I don't suppose there's a service manual for that, is there?
