Two (2 pcs) fully tested NOS tubes, platinum matched pair of rare ECC83 12AX7 RFT made in Germany.Made in famous Muhlhousen tube plant, back in 1974.
NOS - New Old Stock
NIB - New In Original Boxes
They are real vintage NOS tubes in original boxes made back in 1974 in RFT tube factory. They are rebranded RSD and they are in original RSD red&black boxes.
I have more than 100 pcs of these tubes and I had enough time last few months to carefully measure them on calibrated Metrix and Tesla tube testers for plate currents and Hickok for transconductance and to make platinum matched pairs with perfectly balanced triode sections.
Surprisingly good sounding NOS tube in hi end audio amplifiers and in guitar amplifiers too!

Size: Large, Color: White, Size: Large, Color: White
I have these same socks in white and gray, oh, and a couple of colors, and they are my favorite socks. They're the most comfortable, best-fitting socks I've ever ordered.

Perfect socks for all day wear
Size: Medium, Color: White
Light weight dry fit. Extremely comfortable very functional fits nice and is not too thick but not too thin. I wouldn’t say they are slip resistant but I am not going to try sliding around in them. I would buy again and choose over other brands I have tried before
