1 X EL34 TUBE. USED. BRAND: BRIMAR. 1960s PRODUCTION. GREY PLATES, HALO GETTER, COPPER RODS. TESTED IN ROEHRENTEST TUBE TESTER: 93% 92.91mA EMISSION (EM) 10.37mA/V TRANSCONDUCTANCE (GM) CH168U1

Merci de consulter mon annonce et de lire le descriptif. ?Général ?? ????Les tubes que je vends mesurés le sont à l’aide d’un lampemetre de laboratoire Metrix U61C, ou d’un AVO MkII. Le tout sur alimentation stabilisée générale. ????Ils sont mesurés selon les paramètres nominaux des fiches techniques des fabricants de tubes pour des données compréhensibles et fiables: donc pas de %, de chiffres sans unité (ex 90, 90 quoi, avec quelles tensions), ou de mesure avec une tension de plaque trop basse par exemple sur un autre point sur la courbe que le point nominal universel. ??Je propose également des tubes non mesurés NOS, new old stock, c’est à dire issus de stocks anciens neufs. Je ne mesure pas les tubes qui ne nécessitent pas de l’être. ??Je peux exceptionnellement le faire à la demande mais ce travail étant fastidieux et consommateur de temps je demanderais un supplément en fonction du tube et du nombre de tubes. ——— ?État? Occasion. Fabriquées par Mullard à Blackburn, code B. OO getter. Voir photos et mesures pour les tubes mesurés pour constater l'état général. ??Les EL34 donnant en nominal 100mA (+ ou -), le Metrix U61 ne mesure que jusqu’à 100mA. J’ai donc choisi un autre point de mesure, tous les parementées identiques à part la polarisation à -14,5V au lieu de -13,5V pour pouvoir mesurer la pente (mutual conductance), et vous donner une idée très précise de l’état du tube.?? ——- ?Achats multiples = frais de port combinés, attendez la facture groupée avant de régler svp. Les frais d’expédition comprennent: les frais de port, les consommables, la main d’œuvre, la commission prélevée sur les frais de port. ?Expédition ??Expédition des petits tubes en lettre suivie à bulles bien protégée ou en colis. J’ai l’habitude et n’ai connu que 3 tubes cassés durant le transport sur plus de 10 000 tubes vendus. Pour les tubes coûteux, je ne propose qu’une expédition en colis. ??En moyenne sous 4 jours ouvrés, en détails de 2 à 15 jours ouvrés très grand maximum après réception du paiement.Concernant les délais, je ne suis pas Amazon, mais je ferai au plus vite, au mieux, et surtout avec grand soin pour éviter que vous ne receviez votre objet endommagé (en tant que collectionneur moi-même, j'aime expédier un objet de la manière dont j'aime en recevoir, à savoir très bien protégé, car c'est un crève-cœur de recevoir un objet ancien qui avait pourtant conservé son état des décennies endommagé à cause de la négligence d'un expéditeur). ??Donc si il est essentiel pour vous que votre achat soit expédié ultra rapidement, veuillez s'il vous plait soit me contacter pour savoir si ce sera possible avant votre achat, soit renoncer à votre achat. Merci pour votre compréhension. _____________________________________________ ?Infos ??N'hésitez pas à me contacter si vous recherchez des lampes en particulier. Je vais petit à petit reconstituer ma boutique avec ma spécialité, les lampes (vacuum tubes, tubes à vide), j’en ai 40 000. 80% NOS, 20% d’occasion. ??Je parle anglais????????.

Matched quad of used but very strong RFT EL34 tubes. Equivalent to 6CA7. This is long base version of RFT EL34. RFT EL34 tubes were often rebranded by Siemens, Philips and Telefunken. Siemens actualy never made any EL34 / 6CA7 in their plants, so Siemens EL34 are rebranded RFTs. All four tubes are used. You are bidding the tubes on pictures. They were tested on modern Orange VT-1000 tube tester. Results are*: 1st tube (Serial: 828189): Good; valve matching value = 12 2nd tube (Serial: 828189): Good; valve matching value = 12 3rd tube (Serial: illegible): Good; valve matching value = 12 4th tube (Serial: wiped out): Good; valve matching value = 13 *Typical test result for EL34 tube on this tester is 10-11 on a scale from 1 to 15. In general, a higher number indicates a newer or less worn valve, however due to manufacturing tolerances, a range of values are possible, even with new stock. So, lower test result does not necessarily means that tube was used. According to tester’s manufacturer, tubes with result up to 2 figures apart can be considered as matched. In addition, the tubes were tested for 30 minutes in a real guitar amplifier to make sure you get a product free from defects. They sound great! Please read RFT EL34 reviews on the web. Here is one example: When I think of German power tubes I think of a big warm sound that doesn’t cause listening fatigue after an hour of playing. [...] These tubes are extremely warm sounding and if you have one of those amps that sounds thin at lower volume levels, these should take care of that problem in short order. Midrange response seemed slightly skewed toward the bass side. This is no doubt where the extra warmth is coming from. The high end was smooth and clear without a trace of harshness. (from EL34 /6CA7/ KT77 tube review on thetubestore.com by John Templeton)
