Product Summary

The "Crown Jewelry" ECC83 tube is here! If you've been seeking the reference tube sound then look no further. Designed for high end amplifiers and preamplifiers, Telefunken ECC83 tubes provide high level gain with ultra low noise and are unquestionably the vintage tubes sought after and treasured most by audio professionals and enthusiasts. 

Sound Qualities

Like any other Telefunken tubes, these ECC83's are very pleasant to listen to: liquid, euphonic, with a slightly warmer midrange than many other German tubes, which makes your sound experience smooth and non-fatiguing, and all that happens on a unbelievably realistic holographic sound stage, where everything feels bigger, wider and taller. Sound texture can be felt through infinite levels of details, laying on top of each other, both in depth and in width. So your quest for superb sound clarity can end right here. Lastly, it never gets old to say that no other brand is even close to these when it comes to low noise - Telefunken tubes are "extremely" quiet just as legend has it.

Professional Tube Testing

NO shorts, leakage or gas. NO noise or microphonics.

Both tubes tested NOS (100%+ nominal mutual conductance) and tightly matched on a reliable and recently calibrated Mercury 2000 tube tester with the following results for mutual conductance:

Tube 1: 1,100/1,050 (110%/105%)
Tube 2: 1,180/1,080 (118%/108%)

Good tubes start at 700 and new tubes (incl. NOS/NIB) 1,000, and the Mercury 2000 tester's rated mutual conductance (nominal) for new tubes is 1,000. Test results can be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to tube's ability to amplify sound, so the higher these numbers the stronger. 

Appearance & Cosmetic condition

Beside the fantastic sound signature, we treasure this pair also because both tubes have 100% paint & lettering remaining and the identical Berlin date codes are perfectly visible on both tubes:  

B 8104901 (B = Berlin, 4 = 1964)

And of course the diamond mark on bottom - the symbol of the best sound one can ever find on ECC83's.

Packaging

This pair of tubes will be packaged in USED old-style Telefunken tube boxes, secured by a handmade paper ribbon (by courtesy of Soundlumia.)

Return Policy - Please READ carefully

Returns are acceptable if we made a mistake by delivering you wrong or defective products. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation TWICE: before they are approved for listing AND before we ship them to customers. So the "defective item" case doesn't exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes are faulty and we will open disputes with eBay. Sound experience is very subjective and we do NOT accept returns because you do not like the tube's sound signature or because you changed your mind about your purchase. Please contact us to work things out before submitting return requests claiming "item is defective" or "item not as described" or "just didn't like it" or "changed your mind."

Tube rollers abusing the return system will be reported to eBay immediately and negative feedback will be left to your account - that's guaranteed. We have already opened several dispute cases to report abusive buyers and eBay has always ruled in our favor. International buyers who request return or refund claiming your country's import duties or sales taxes/VAT/GST are too high will be reported to eBay immediately for dishonesty and will be permanently blacklisted from purchasing from Soundlumia. We are committed to working closely with eBay to help rid the marketplace of dishonest, unjust, unreasonable, abusive buyers that are detrimental to the vintage tubes market and the audiophile community.
