RFT NOS 12AX7A Vacuum Tube For sale I have a single NOS RFT made Amperex branded 12AX7A ECC83 vacuum tube. East German manufacture and very distinctive construction which is RFT. A very good, livelier tube. Carefully tested for transconductance, shorts, gas, life. No tube is sold that has any gas, leakage or fails life and strength tests. Photo is of the actual tubes on auction. I take a great deal of pride in the honesty of my representation and the quality of my customer service. There will be no unwelcome surprises with my tubes....guaranteed. Test Results:1900/2200 gm (Triplett 3444) Minimum:1000/1000 gm (Triplett 3444) Test Equipment: Hickok 539C w/ Fluke 73III multimeter Triplett 3444 Hickok KS-15874-L2 Cardmatic Maxi Matcher w/ Sola CVS Regulated Power Supply The Hickok 539C is a highly regarded transconductance tester. The Triplett 3444 is one of the finest testers ever made. Exceptional in every aspect. Superb with directly heated triodes. The Hickok KS 15874-L2 is a commercial version of the wonderful 118 Cardmatic. In my opinion, and the opinion of many tester experts, this is the best tester that was made by Hickok. A real gem. The Maxi-Matcher is a useful tester for measuring current draw and transconductance at 325/400 plate volts with 5 bias voltage settings. Very good with 6V6s and EL84s, this tester falls a bit short of true operating levels on 6550s, EL34s, 5881s and 7027s. Still much better than most suitcase testers for measuring power pentodes. I do not trust the minimums on this tester and they are therefore not listed. The industry standard by default. ALL of my testers (except Maxi) have been calibrated and redone by Chris Haedt. ===== Fully Guaranteed! ===== Money back on these tubes if they do not operate and test as described! ALL my items on eBay are genuine, authentic and original. As with all of my auctions, authenticity is assured so please feel free to bid with confidence! Shipping: U.S./Canada: FREE First Class / Ebay International: Ebay All tubes shipped within 24 hours of payment. Tubes are shipped upright, in oversized boxes with packing peanuts and bubble wrap. Additionally, I insert filler in each tube box to prevent movement of the tube within the box. Bulk lot tubes will not be individually boxed. Looking for more quality tubes? Check out my other auctions. Take a look at my feedback and bid with confidence. Combine auctions and save on shipping! Fine Print Only place a bid when you are seriously interested in this particular piece and when you are truly willing to fulfill all the obligations according to eBay rules. After Winning an Auction, according to eBay rules, please respond within three days! Payment including actual shipping & insurance fees is expected within 10 days. I use the U.S.P.S. exclusively for shipping. Quoted shipping prices DO NOT include insurance. Often, I will require Paypal users to insure shipments and/or use trackable shipping methods with signature verification. If the buyer chooses not to insure a parcel, I am not liable for loss, damage or theft. If payment is not received within 10 days, the item will be relisted and negative feedback will be given.
