Don't use a wirewound, that's not the right type for this spot. A one watter would almost certainly be OK if that's all you can find. 100 milliamps over 100 ohms is one watt - should the screens draw more than that? Looking back, I'm guessing the parts I used were only one watters as well.
If you really get stuck, send me a PM and I'll dig through my box and see if I've got four more of those 82 ohm parts left.
Ty,
A low value wirewound has barely more inductance than other resistor types since they have very few turns. Is there some other reason you recommend against using them. I do agree that no inductance is best, but I've used w/w without difficulty. Guitar amps use them quite often too. And larger wattage carbon comps are near impossible to find.
Let me know! Thanks.
