I have nylon spacer bars in C1 & C2 in my commercial made GS35b amp, (4 in each 
cap) and every one of them shows signs of heat stress (melting & burning) I'll 
swap them out one day for PTFE, but haven't got there yet...

For decades I’ve avoided using nylon hardware in the vicinity of an RF
tank circuit because I believed nylon was prone to absorbing RF and
burning. I don’t know how or when I came to learn this information,
but now I’m wondering if I’m wrong. Normally I use  brass hardware.
Had anyone else heard this caution?
