211 -The Next Generation- Part 15 : 6HS5/211 finished
Finally here are photos of the finished 211 mono amplifiers with 6HS5 driver.
The development of the layout and the assembly have been shown in previous posts. This is how the finished amp looks like:
The dimensions are: 320mm wide by 620mm deep. The wooden body is 125mm high. Overall height about 310mm. Quite some boat anchors!
Both amps side by side:
First I was a bit sceptical if the design with the many transformer covers on top would work. But as it was finished, I liked it a lot.
View from the top:
The sockets of the driver and rectifier tubes are mounted a bit recessed below the main plate to provide a good clearance distance for the high voltages.
