That is a weird (to me) way to connect those filaments on that Fisher. It looks like they are using the filaments to bias the output tubes ... wow! I recapped a small signal tracer this week which uses a 12AX7, when I powered up to test, it flashed like you mentioned. It's a Mullard. Still don't think it is anything to be concerned about.
