2A3 Push Pull

A 2A3 Push Pull amp is as perfect of a 10 watt amp as you can get.



This amp was designed to be a throwback to the start of higher power audio reproduction.
Inside there are no electrolytic caps, only film used with a MOSFET capacitance multiplier circuit.  It employs 6SL7 to 6SN7 to 2A3 with fixed bias.  Latest version uses high capacity chokes. 

This amp is built like a tank.  We had it temporarily on a shelf for storage and the shelf gave way.  The amp landed on the floor and gouged the wall.  The only damage was a slightly bent tube pin on one of the 2A3s
