I had a similar problem with my tube amp. After giving manufacturer a hard time about it turned out my outlet wasn't grounded and way amp was designed the ground is important. Wasn't a problem with previous amp because it was vintage and two prong plug. Ran a ground wire directly to fuse block and solved problem. Can get one of those $5 outlet testers to check and see what manufacturer says about it.
Can someone tell me what wrong
Hi there
i need some held with speaker hissing noise
i recently noticed some noise come from my right speaker
the speaker is venture audio grand mk3 and driven by vta m125 tube mono block, it’s kind of loud, i can hear it from 4 feet away the speaker with the preamp turn off, it doesn’t effect by the preamp volume
so here is what i did
Remove the preamp - still the same noise
swap the mono block - still the same noise
swap the speaker cable between left and right - still the same noise
hook up a vintage dynaco st70 - no more noise
hook up the right channel mono block to the left speaker - no noise
so what could be wrong here?
I didn’t have that noise before
This thing really drive me nut
Thank in advance
