For sale by original dealer a 47 Labs Gaincard solid state amplifier in very good condition. This is the 50 watt version with external power supply included. Unit looks good (rating a very conservative 7) performs flawlessly and sounds excellent. I no longer have original box but will pack exceptionally well for shipping anywhere 110/120 v. is standard. Retail is $4,000 and I am asking $1,900 or best reasonable offer. Please call 508-446-7103 or email Ted@HighEndAudio.com with any questions or to purchase.
