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
