Matched Pair Ken-Rad 6V6 6V6GT Vacuum Tubes Valves

This matched pair of Ken-Rad 6V6GT output tubes was tested on our Maxi-Matcher 2 for shorts, gas and transconductance. There were no shorts or gas.

Plate current measured 17.5 milliamps and transconductance was 2400 micromhos for Tube One. Tube Two measured 18/2260. (New US-made 6V6s typically test with plate current from the mid-teens to mid-30s with transconductance from 2300 micromhos or so.)

These tubes have tall bases; standard black bottles and copper support rods.

I am playing them in my Mini Mite as I write and they sound super.

1. MOST OF THE TUBES WE SELL ARE OVER 70 YEARS OLD. WE CANNOT GUARANTEE FOR FAILURES AFTER POWER UP AS THERE IS NO WAY TO DETERMINE HOW TUBES WILL INTERACT WITH YOUR ELECTRONICS OR IF THEY WERE MISTREATED IN TRANSIT; NOR IS THERE A WAY TO DETERMINE WHETHER THEY MAY HAVE FATAL FLAWS! WE CAN ONLY TEST FOR THE PARAMETERS MENTIONED ABOVE. WE CANNOT TEST FOR CATASTROPHIC FAILURE. IF A TUBE FAILS AFTER YOU GET IT, IT IS YOUR TUBE THAT HAS FAILED. THERE IS A .1 % CHANCE THIS MIGHT HAPPEN. BE WARNED. NO REFUNDS IN SUCH CASES.

2. IN A 22 TRANSACTIONS ON REVERB AND OVER 8000 IN BOTH ETSY SHOPS, WE HAVE HAD FEWER THAN A DOZEN LESS-THAN-FOUR-STAR REVIEWS OR HAVE LOST A CUSTOMER BECAUSE I REFUSED TO EITHER ISSUE A REFUND FOR A TUBE THAT WENT BAD AFTER IT HAD BEEN USED OR A BUYER KNEW NOTHING ABOUT TUBE REBRANDING AND CLAIMED THAT SOMETHING MADE, FOR EXAMPLE, BY TUNG-SOL AND BRANDED BY EMERSON WAS MADE BY EMERSON, AN ELECTRONICS COMPANY THAT NEVER MADE TUBES!

3. TUBES ARE GUARANTEED GOOD ON SHIPMENT. IF YOU FEAR DAMAGE OR LOSS OF PARCEL IN TRANSIT, PLEASE INSURE THEM! OUR SHIPPING RESPONSIBILITY ENDS WHEN THE PARCEL IS ACCEPTED AND SCANNED BY THE US POSTAL SERVICE. SOMETIMES THERE ARE INITIAL SCANNING DELAYS. WE HAVE ACCESS TO THE SAME INFORMATION YOU DO AND IT IS YOUR RESPONSIBILITY TO DEAL WITH THE USPS SHOULD THERE BE DELAYS OR LOSS OF A SCANNED PACKAGE. PLEASE BE PATIENT FOR THE FIRST DAY OR TWO IF THE PACKAGE IS STILL MARKED AS "PRE-TRANSIT." WE SHIP THE DAY AFTER THE SALE IF THE SALE WAS AFTER 9:30 AM EASTERN TIME.

4. THIS IS NOT AMAZON. THERE WILL BE NO REPLACEMENTS FOR LOST PACKAGES OR TUBES THAT FAIL. IN PRACTICE THIS MEANS YOU TAKE ON THE RESPONSIBILITY FOR THE LOSS IF THE PACKAGE IS MARKED AS "IN TRANSIT" OR AS "DELIVERED." MAIL GETS MISPLACED, STOLEN AND LOST. SOME COUNTRIES DO NOT HAVE INTERNAL TRACKING. CHINA IS AN EXCELLENT EXAMPLE. IF YOUR COUNTRY IS SIMILAR, IT IS YOUR RESPONSIBILITY TO INTERACT WITH YOUR CUSTOMS AND POSTAL AUTHORITIES TO FIND THE PACKAGE. CUSTOMS DELAYS CAN ADD WEEKS TO DELIVERIES.

5. I BUY TUBES IN BULK. 10-15% OF THEM ARE NOT SUITABLE FOR HIGH END AUDIO APPLICATIONS. THAT LOSS RATE IS REFLECTED IN OUR PRICES. I LISTEN TO THESE TUBES IN TUBE EQUIPMENT. SOMETIMES TUBES THAT TEST WELL HAVE PROBLEMS AND SOUND AWFUL. THAT IS ALL I CAN DO. IF THERE WERE A TEST FOR FUTURE FAILURE, I WOULD USE IT. THERE ISN'T. THERE IS RISK IN LIFE. THESE PRODUCTS ARE NO LONGER MADE. THERE ARE NO MANUFACTURERS TO TAKE PRODUCT BACK BECAUSE OF DESIGN FAILURES OR QUALITY-CONTROL ISSUES. THE PRODUCT DEVELOPMENT AND IMPROVEMENT CYCLE IS OVER.
