Go ahead and swap them out. FWIW, I switched out my preamp tubes for some NOS Philips i65's and I believe I got reduced background noise as a result. I can't fully verify that, because I also swapped out the power tubes at the same time. You can't hurt your amp by trying preamp tubes of the same value.groundmeat wrote: ↑Sat Jul 13, 2019 8:15 pmTook the amp to the Guitar Center in Atlanta, the main one for my state. Talked with their best "amp guy" who was on duty. We plugged the amp up among the sales floor amps to demonstrate the noise, but... it's the Atlanta Guitar Center, so there's NOISE NOISE NOISE always, and we really couldn't hear it. When I sat down in front of the cab with the guitar, I could hear it, but with all the noise going on (2 old guys camping out all day on the Fender amps using the place as a jam space, drums, other guitars, basses, people in the DJ area, it was nuts), it was camouflaged. So... he did a really swell thing, and he went the extra mile, and he grabbed a 4x12 with wheels from the floor, and we carted my amp back to one of the lesson rooms in the back to really hear it. He said... it was a normal thing. He also said he personally owns a Mk3 Rockerverb, and his does the same. He grabbed a Boss Noise Suppressor pedal and hooked that up and tried to show me how it might help. It did a little bit on the dead air spaces, but there was still that white noise thing just behind the notes.
Anyway. Did what was recommended here by people. Actually got some friendly help this time, and it seems like it's a "normal" thing. I dunno though. I'd still like to dig further and see what I can do with different tubes to at least alleviate SOME of the noise if it's at all possible.
I tried to get the guy at Atl Guitar Center to see if it was kosher with the 2-year warranty to swap out preamp tubes, but he never got a text back from the person at Orange he was trying to contact.
So if anybody from Orange reads this... HI! And is it cool if I swap out preamp tubes? NOT poweramp tubes. And not the two 12AT7's for the reverb and FX loop. I would ONLY replace the four 12AX7's for:
