Hi all, quick question.
Sweetwater had a good deal on an evh 5150 100S Stealth amplifier and I wanted to give it a shot. According to the sales rep the amp is a demo and is like new but was quickly returned by a customer because they didn't like the red channel so they put it back up for sale.
Amp looks in great shape, and it sounded great too, but I think one of the tubes is bad. I just happened to look through the back and noticed one of the four tubes was dark, no lighted filament, cold to the touch.
I opened the back and tried switching the tubes around, same thing that one tube is just dark. So i pulled it and took a pic. 2 things:
#1 according to EVH's website, the 5150 100S uses Shuguang 6l6 tubes. According to some sales websites including sweetwater, the same amp is listed as using Wing C 6l6s, so I don't even know what tube it's supposed to have, which leads to...
#2 This is the tube I pulled from the amp, it says groove tube. I'm not a tube expert, i just want to get whatever evh ships stock back in the amplifier. Are groove tubes generic tubes? I thought they were a type of Mesa Boogie tubes but there's no MESA logo on the tube. Pics below of the tubes. Can anyone tell me what type of tube this is so I can try to find them online, or, just let me know what was stock with this amp? I googled shuguang 6l6 tubes but apparently they're discontinued or something. If that's true how is EVH putting them into their amps.
Anyway, sorry for all the questions, just frustrated because I took a chance on the demo and am bummed to find the bad tube. I feel like now I gotta check all the preamps just in case that guy who originally got it did a fudge job trying to replace everything.
Even with 3 tubes though the thing sounds pretty great for my purposes haha
