211 SET 40W output design and mfg


Posted on Feb 7, 2014

An amp that uses 211 or 845. It puts out just over 40 watts. The tube must run in A2 to get this power, which is not a problem with a good driver. The secret is a good follower, you use a 6BQ5, I use a mosfet. You use 7K ohm load on 1000 volts, I use 10K ohm on 1100 volts. Both simulate to about 40 watts using Tubecad SE amp cad. It should work very well and sound nice.
