Brand New Plate Current Matched Pair 2x Sovtek 6550WE Vacuum Tubes

  
Brand New Plate Current Matched Pair (2) Sovtek 6550WE Vacuum Tubes. The Sovtek 6550WE features a higher transconductance, higher output power, and an excellent sound performance. It will bring out that excellent range for any guitar amp. We test and/or match our tubes by Gm & Plate Current using a state of the art digital Maxi-Matcher tube tester. The Maxi-Matcher simulates a real circuit and tests tubes in real-world conditions.

We also check our tubes for other issues like shorts on calibrated and vintage tube testers. We match our tubes +/- 5% with an overall tolerance of 10%. While we do screen for noise and microphonics, even the best tube testers are quite bad at finding these faults. The only real test is with your ears.

We guarantee that our tubes will be free of noise or microphonics but please be aware that there isn't a whole lot we can do to ensure your tube won't be. We guarantee our tubes for 90 days upon receipt.

Noise and/or microphonic issues are covered. This item is in the category "Musical Instruments & Gear\Guitars & Basses\Parts & Accessories\Amplifier Parts". The seller is "onlyglass" and is located in this country: US. This item can be shipped worldwide.
