I am selling of my 12AU7 and variant tubes because I don't have a need for them anymore and here are two Philips made in Holland ECC186/7316 SQ (special quality) tubes. I tested these on a calibrated Hickok 800A tube tester and the results are as follows:
Tube 1 (the one with lesser of the logo) Triode 1 is 1,700 and Triode 2 is 1,800.
Tube 2 (obviously the one with more of the logo, almost perfect) Triode 1 is 2,200 and Triode 2 is 2,100.
The date code for tube 1 is delta 3G (1963)
The date code for tube 2 is delta 5K2 (1965)
The pins look virtually new on these tubes and I bought them about 4 years ago, but never used them. I did have another set of Amperex ECC186/7316 tubes and the sound is phenominal. These are one of the best sounding 12AU7's ever made. Do a search on them. The ECC186/7316 is a specially selected 12AU7 that has low/no microphonics and are the quietest available of the 12AU7's. They have small halo getters and 14mm gray ribbed plates. They have the original boxes that are in very good condition, one of the inner flaps on one box is torn off but is still included, the other box is fully intact.
I am looking to get $110.00 plus actual shipping for them. These are quite rare and are one of the best sounding 12AU7's available and therefore are worth more. I think I paid $130.00 for them, but as I said I never used them. Below are some pictures of the actual tubes.

Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
"I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion."
My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....
