I think they were referring to the wirewound resistors typically encased in a flexible cloth like fabric, might be asbestos, so be careful. If they're not open, they're probably good. Note bene, previous remarks about today's line voltage, especially on line operated battery sets. If the filament voltage is too high, add on or replace this resistor with one of a higher resistance to get the supply voltage back in line. I have doubled the value in the '46 and '48 "roll top" portables after recapping, and still get great sensitivity and plenty of volume. Use a 5 watt type, better yet a 10 watt type, and keep it away from other components.
