Review on 🎶 Nobsound Little Bear T11: High-Fidelity Vacuum Tube Phono Turntable Preamplifier for LP Vinyl Records by Byron Elliott

Bought for my old Technics SL-1200mk2. It arrived very well packaged and after setting everything up and warming it up I rolled up one of my favorite vinyls. Instead of music, I heard a jiggling/pulsing noise coming from my speakers. not okay! I turned everything off and reinstalled the tubes only to hear the same thing. not cool. I have other tube gear, so I grabbed three 12x7 tubes from another amp and plugged in (and switched the tube selector to the correct tube type. No pumping or frizz, just a nice tone (they're good tubes). Like others who do that Product design of these parts is a joke with the way they placed the RCA jacks and ground tab on the front panel it ruins an otherwise nice unit If I decide to keep it I will do an internal ground, to get rid of it .must be grounded *internally*!) I expect the seller to get in touch and swap tubes for known good ones or I'll be returning these preamp boxes.
