Is it just me or is everyone else having similar luck changing the tubes in the Dark Voice OTC?
I’ve spent upwards of $300 dollars buying the tubes people are recommending and all but the one that came with it HUM very noticeably. I’ve tried to burn them in as other people said to do and they still hum. I just got another one in the mail today, I crossed my figures and put it in, freaking hums louder than the others. Today’s pick was a Tun-Sol 6SN7GTB. I am so discouraged! Any ideas? I’m not a wealthy person by any means, in fact I’m disabled after 22 surgeries. I’ve also had an electro-harmonix 6SN7EH I don’t have the other two info handy to inform you. What do I do?
