One (1 pcs) fully tested NOS tube, rare ECC83 12AX7 Siemens Halske made in famous Munich tube plant in 1967.

Ribbed plates with one side hole, dual getter support version.

Low noise and no microphonics, perfect for use in microphones.


We have few 100 pcs boxes of these tubes and we had enough time last few months to carefully test them for plate current and Hickok for transconductance. We have also tested them for noise and hum in our phono RIAA preamp.

They are real vintage NOS tubes, made in West Germany in 1967, carefully selected from big batch. They come in generic white boxes. They are the same batch numbers engraved during sealing  I63 =7P, also the more specific internal codes 220 and 221 are printed on every tube.

These are really nice sounding ECC83 12AX7 tubes, very detailed sound, great resolution and transparency and low noise. I have found exactly the same tube, from the same batch, factory branded E83CC by Siemens, it says enough for quality of these tubes, just to mention that E83CC has 10000 hours warranty for all parameters.

Suit looks great for fun formal events
Size: X-Large, Color: Green
The style and fit are great. I did notice a white thread in the shoulder poking out. I used a marker to darken it so it was not noticeable but other than that this suit really looks great. We have a music event in a couple of weeks that I am wearing this to and think it will delight as a sharp but different. I was also happy that it did not require alterations, sleeve length was on spot and everything fit great (XL) also this is a slim fit but I am not that slim and it fit nicely on me. As long as it doesn't disintegrate during the event I will consider this money well spent.

Very stylish & tailored fit
Size: Small, Color: Pink
My husband purchased this suit as a “flower-bro” at my sister’s wedding. Unfortunately the color theme for the wedding was changed so he had to change it out which I was sad about because it fit him very well and looked great! The quality was good and the fit looked tailored.

Loved it. Fit well, sizing was good, however think I could have gotten my son the next size down. We ended up buy a smaller size pants.
