Thanks guys… I popped the case open and swapped the left channel tube with the right channel tube, and the noise I was hearing followed the tube and is now coming through my left channel. Cool.
Should I be concerned about continuing to use my preamp while I wait for a new pair of tubes?
Any recommendations for where to order a matched pair of Sovtek 6h30’s?
looks like tctubes.com has them listed at $89.00/pair and vivatubes.com has them listed at $127.78. Thetubestore.com doesn’t seem to have them listed for sale in matched pairs, but has them at $53.95ea. In any event, I’m unfamiliar with all three of these companies so some guidance would be much appreciated.
curious about your suggestion to unplug everything for 24hrs…
