Abraxas Audio single ended 47 tube amplifier - SET amp like 45 or 2A3 [Expired]


no longer for sale

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.
