that have the usual spring-type shock absorption, but that would make the tubes less "showy".

I understand, when I build a guitar amp the customer usually wants the tubes to glow out the back.
For that I use the "bare" spring retainers like this. Usually just on the output tubes (6V6s and such) since they're the showiest, but they make them in AX7 size also.
