VINTAGE SYLVANIA 2A3 VACUUM TUBE TRIODE 4C DATE TV-7D/U - 67 / MIN 38 Up for consideration is a Sylvania 2A3 vacuum triode - used but tests strong for an 80+ year old tube. The minimum good TV-7D/U reading is a 38, or 2,500 umhos.  This tests 67, or 3,350 umhos.  Class A configuration according to datasheet quotes 5,250 umhos. 3,350 is 63.4% of that value.  Range C is used for the 2A3. Single black plate construction; appears remarkably similar to the RCA I sold just a short time ago. Date code is 4C which appears to mean 1934, March (C) after a fair bit of research. What you see in the pictures is what you will receive.  The test done is the only testing done.  If you have questions or need further information, ask.  All sales final due to age.  It will be packed beyond well.  I recently sold one to a gent in Switzerland - it was triple boxed...as an example. Thanks for looking! Note: if the tube sits, it’ll get up to 68…I give it several minutes for the numbers I put in ads. Thanks

Je préfère bien sûr une remise en main propre, mais je peux expédier à vos risques et périls. Je vais faire un emballage blindé et le plus sûr possible. Les amplis fonctionnent très bien et le son est exactement ce que lon attend des amplis TRIODE SE (consultez mes évaluations). ON PARLE SUR INTERNET : «FORCE : Purement musical, clair, naturel, je ne peux pas penser à une meilleure performance - ce sont des amplis exceptionnels (avec les haut-parleurs à haute efficacité appropriés). FAIBLESSE : Aucune (sauf dépendance à lefficacité des haut-parleurs)» AUDIOREVIEW.COM «Que puis-je dire. Ils doivent être quelque chose de très spécial (et croyez-moi, ils le sont). À mon avis, ce sont lun des amplis SE Triode les plus sous-estimés. Je dois admettre que jadore le son des tubes 2A3 et, pour moi, ils sont plus musicaux et justes que les tubes de sortie 300B très appréciés (cest peut-être une question de goût personnel, bien que le manque de haut-parleurs à haute efficacité sur le marché rende plus facile à comprendre pourquoi lindustrie se concentre sur les 300B plus puissants).» Si le prix de vente dépasse 1500 euro, je rajoute les deux câbles d’alimentation 3x6mm2, C-004 et P-004E (Beryllium Copper) présentés dans les dernières photos (ils ne font pas partie de la vente).
