I built a Class A tube amp!

[PRR]

Despite the differences in ratings, modern 5881 should take anything a 6L6_ will take.

However I see 22W plate dissipation, assuming 400V raw supply, 20V on Rk, 14V on plate dropper, 10V in OT DCR, and 5% screen current.

Here's the latest revisions. Added another RC network, split the RC networks, both driver and power have their own now. Added Bleeder Resistor after C2. Added grid stopper on inputs.
