Usually I've found HFE that goes to 120/140 of one type and 70/90 for the other type, that is not good for a matched pair to use in PP configuration, so I had the chance to find some bags of original Telefunken transistors, BD135 and 136, tha t are identical to the more used 139/140, that just hold less voltage (45V instead the 80 of the BD 139/140, but usually you don't need 80V to run a headphone or a line amp).The bags had the selection for HFE, so I've been able to select some matched pairs of transistors, within max 10% range (but usually is better, around 6/7%), more than sufficient for a matched pair for audio use, Beyond this, the audio quality of Telefunken transistors is always a warranty The transistors has been matched with an Atlas DCA55 tester, so at your home with your tester could measure different, I don't accept any return if you read values you don't like on your tester The transistors are shipped safely packed in cartonboard and bubblewrap CHECK MY OTHER AUCTIONS for other cool vintage components and Hi End capacitors SHIPPING to US, PRIORITY MAIL (shipping receipt, but no tracking number) costs 6,5$, REGISTERED MAIL (shipping receipt and tracking until the ITALIAN BORDER ONLY) costs 13.5$ S&H and Paypal fees included SHIPPING to EUROPE, PRIORITY MAIL (shipping receipt, but no tracking number) costs 5,5$, REGISTERED MAIL (shipping receipt and tracking until the ITALIAN BORDER ONLY) costs 9,8$ S&H and Paypal fees included PLEASE READ WELL: TO GREECE AND CENTRAL/EAST EUROPEAN COUNTRIES (Russia, Czech Republic, Poland, Hungary, Romania and Moldova, Croatia, Lithuania, Latvia, Estonia, Slovenia, Slovakia, Bulgaria, Ukraine and Belarus, Serbia, Montenegro, Bosnia and Herzegovina, Albania, Kosovo, Macedonia): I SHIP ONLY REGISTERED MAIL The shipping towards non UE countries may be subject to DELAYS caused by the CUSTOMS TRANSIT.
