Up for grabs is an excellent NOS/NIB set of Sylvania EL84/6BQ5 tubes. These 2 NOS tubes are an excellent MATCHED pair of outstanding vintage USA produced EL84/6BQ5 tubes. Earlier production with the more desirable Black Plates and ring getters. One of the best and most popular choices for use in guitar amps because of their affordability and incredible sound qualities that the Sylvania EL84/6BQ5 tubes are known for when pushed into natural distortion. Also an excellent choice for HiFi applications as well. Very strong tubes with excellent above NOS test spec results. Just an honest top quality set of tubes at a great price. Tubes have undergone high quality full parameter testing for Gm Ip shorts and gas with results as shown. Ships in the original Sylvania boxes which show age as pictured. Don’t miss !! Tubes undergo dual testing procedures whenever possible. Analog tested on a fully calibrated and modernized Hickok 539c and digitally tested and displayed on the Divo/Orange tester for its ease of interpretation by buyers. As a result, you are assured to be getting some of the finest quality, fully tested and proven vintage tubes available for sale. ******************************************************************* Hickok 539C results: Tube 1 = 11,025 Gm/ 49.2mA Tube 2 =11,640 Gm/53.6mA Hickok 539C Minimum = 5650 Gm Avg. Nominal NOS spec for EL84/6BQ5 = 11,000 gm / 48.0 lp *************************************************************************** Tubes have passed all the following tests: Heater filament test: Short circuit Heater filament test: Open circuit Heater filament test: Tolerance check Heater cathode insulation: Leakage Heater cathode insulation: Short Circuit Tests for heater current abnormalities Amplification factor Voltage gain Power gain Screen grid test Mutual conductance test Dual test for double triodes Emission Inter electrode leakage Inter electrode short circuit Flash-over (arc detection, high voltage breakdown) Gas ionisation test *** SALE TERMS - PLEASE READ COMPLETELY *** All my tubes are listed under the “parts OR not working” category because tubes are in fact parts for amps but main reason being its the only way ebay honors a true no return listing. This is the only way to prevent a very small number of unsavory buyers from purchasing tubes in order to be able to audition their sound in their equipment and then abuse the ebay buyer protections to be able to force a return weeks later. Obviously that is a situation sellers can not endure particularly when dealing with NOS tubes at times. Your understanding for why that has to be done is appreciated. Please ask any questions or concerns and I will do my best to respond promptly. USA SHIPPING ONLY. Please check my other auctions for other rare and hard to find tubes that are also available with many fresh vintage tube offerings added constantly. All items will be very well packed and shipped the next day whenever possible. Although I DO NOT ACCEPT RETURNS because of the sensitive nature and personal tastes associated with vacuum tubes, I will certainly work with any buyer to address any problem that may occur such as a tube that arrives damaged in shipping etc. I require any buyer that encounters a problem to notify me within 72 HOURS after receipt of a pending issue. If as a buyer, you feel you can not adhere to the sales terms of my listings, I kindly and respectfully ask that you do not purchase tubes from me. Unless specifically stated in the listing and commonplace amongst the majority of tube sellers, I do not warranty or make any guarantees related to noise, hum or microphonics. As is commonly known tube testing results do not translate between different brands of testers and the different approach each manufacturer used to achieve their test results. As a result all tubes listed for sale are represented and sold strictly off the results shown and provided by the testers used in the listings. All the testers used are some of the most respected models ever produced and are professionally calibrated regularly by the best techs in the business. Calibrations are checked regularly using bogie tube sets dedicated for each tester. All of which ensure solid and accurate results for the tubes tested and confidence for the buyer in the vintage tubes being purchased. Therefore please let it be understood that I will not guarantee or compare the results off any other testers nor will partial refunds be granted based off unknown testers and their obviously unknown condition and accuracy. As a courtesy, every tube I sell is cleaned and treated with Deoxit to remove 50+ years of corrosion and grime. For Best Results DEOXIT Your Sockets!! FEEDBACK: I will leave excellent feedback for the buyer once I receive their feedback indicating they have received their item in good condition and are satisfied with the transaction and their buying experience.

Novel B9A Test Lead Plug PCB for e.g. ECC83 and EL84 etc Valve Socket Flying Leads. For experienced Engineers only. A very useful plug that can be used for either engineers test fly leads, mounting a valve with fly leads in a remote base, or with the addition of another valve socket mounted on top of this plug/the appropriate hardware change the pin configuration for a different type of valve/pin out without the need to rewire the original chassis socket base. Observe safety precautions at all times from electric shock/disconnect from mains before working, and only recommended for use by experienced engineers who are used to working at high voltage and with valve technology. Always refer to manufactures data on valves, as pin-out varies between different valve types. Note the pinout of an ECC83 and the EL84 are different, so the Low Tension and High Tension voltages will appear on different pins. They are only given as examples as Novel/B9A bases. Valve equipment uses high voltage, there is risk from electrical shock and equipment can make big bangs under fault conditions or incorrect wiring to untrained purchasers. The seller accepts no responsibility. Check photos before bidding, no returns
