So what 2A3 amp did you pick up David?

Tekton Double Impacts
@corelli It's Scott Sheaffer's Found Music 2A3 There isn't much information online regarding it, but there is some here, including pics: https://www.whatsbestforum.com/threads/found-music-2a3-amplifier.4279/ And some tech info, below: "These are 2-stage direct coupled single ended triode design. Rectification uses mercury fullwave rectifier tubes Driver circuit is powered and operated as a dedicated amplifier by itself, rectifier is 82 and signal tube is 7A4 Output circuit has own power supply as well rectifier is 83 and tube of course is 2A3 PS and bypasses are Jantzen and Jupiter. UX4 sockets are Audio Note silver and ceramic. The amps are wired throughout with UPOCC copper. Magnetics are nickel from Intact Audio (Dave Slagle). Output with the JJ 2A3 tubes that are stock with it is just shy of 3.5 watt into 8 ohm. The amps are made for a 6-9 ohm impedance." @charles1dad was instrumental in his support and advice, without which I would have been lost in the woods as this is very new territory for me. Thank You Very Much, Charles. |
David, you have acquired an acknowledged , all out assault and state of the art 2A3 SET amplifier. It is designed, implemented and built to the uppermost level. Given your stated objective and purpose/intentions with this amplifier I think you are going to find it stunningly good with the appropriately chosen speaker match. Congratulations on getting this world class power amplifier. Charles |
Very cool amp! I like the over built design and direct coupled driver. Be aware of Mercury rectifiers, they're far more dangerous than the liquid mercury in older thermometers and if broken will quickly spread a fine mist around the room (more so when hot). I would never want to break a mercury rectifier tube in my living room, that's the main reason they were foregone for the more common 5U4, 5Y3, 5AR4 rectifier tubes. |
