FOR SALE: rare and unique Abraxas 47 Tube Amplifier made by Jeff Larson
of Abraxas Audio. Boutique hand built, one-of-a-kind! This is a single ended
direct heated pentode amp, using the 47 tube. Use with efficient speakers or with headphones (has headphone jack)
Jeff said that this amp was his best effort to date (he signed inside - see photos): James output transformers, electrolytics bypassed with film in critical locations, screen power is from a low impedance reserve
assuring full power performance. Wiring is silver on copper Teflon. High
inductance filter choke minimizes cap size. 2.5wpc in pentode and switch for
700mW in triode. Also, headphone output and hum pots. Set for 8 ohms but can
easily be changed to 16. One 5V4G rectifier and one NOS 6C8 dual triode. 5U4
may also be used with slightly lowered power. The 47 tube is akin to the 45 and 2A3, but a lot less expensive.
The amp has a relatively small footprint, is not too heavy and has no bottom plate. Please be familiar with tube amp safety.
I can throw in another set of 47s as a free bonus.
Price all inclusive: amp.tubes, shipping.
Condition: Very nice. Rating at 8. See photos. Boutique hand built.
