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.

What A Find! Unbelievable Quality and Price!
Special Size: Standard, Size: Large, Color: Plaid-light Blue
I can't believe the quality of this shirt!! I ordered the blue checked one for my husband for a costume. The price was right and I didn't expect much, as it was just for a costume. It came packed into a little box, which I figured showed it would be super thin and cheaply made, but didn't really care as only needed it for one time. Woah!!!! I opened the box and was absolutely floored by the quality and heft to the material. It is crazy. I don't know how they get this shirt into that box, but it is baffling. This shirt is of high quality, with all the seems sewn well. The fabric is every bit as good as the brand of oxford shirt that costs 3 times the price of this one. My husband goes between medium and large. He takes 16" neck in dress shirts. We ordered the large and it fits well. Has a little room, but not in a too big type of way. I washed it once before wearing, and it washed well. Not much shrinking at all. It ironed very easily without a problem. Yes, it is 100% percent cotton. Because of the quality and fit, I will now order additonal colors. My husband loves this shirt. This is an excellent buy!!!

Great shirt!
Special Size: Standard, Size: X-Large, Color: Dark Green
My partner loves this shirt and is very particular. He likes the green color and that it is cotton. Bought more colors from this company. Runs true to size.

Amazing quality 11/10
Special Size: tall, Size: XX-Large Tall, Color: Aroyal Blue
It’s an amazing quality shirt. White is bright, not a single thread, all folds are just perfect. I can’t believe I got this quality for this price 🙌

Not too bad for the cost but could be better.
Special Size: Standard, Size: 3X-Large, Color: Navy Blue
I like the shirt. It fits well and color is as described. Main reason for 3 stars is that they do a lousy job with sewing on the buttons.
