Jolida 1000RC Tube ???
I just received my fresh batch of new tubes from Cryoset (KT77) for my Jolida 1000RC. I replaced all of my older tubes even though they are still in good excellent working condition, anyway, all the tubes were replaced, the system was re biased, etc when I went to turn on the system tube number 8 sounded like loud POP. This was strange since I have never experience a weird noise like that. I turned off the system immediately re check the tube and re-started the amp. Everything seems to be working fine now but now I am concern about this tube that sounded like a lOUD POP, wondering if the tube came in slightly damaged or something else went wrong.
