that ClassA xls calculator is wrong.
There is a corrected version.
That's the problem with this Forum. There is no way to correct errors. The Members can simply point out the error, but the erroneous post remains.

it is confused with ClassA bias current and gives the wrong ClassA output when bias is set high.
Efficiency is weird.

From the diyaudio friend, everybody is good, undergoes many day of tests, the result is as follows:
1)KSA50(KSA50-aaw1.1) is perfect.
2)Before the vacuum tube the level amplifier has “BUG”.Mainly displays in the power source not enough peacefully,Is seeking for in the middle of the more reasonable solution.
Therefore, vacuum tube pre-amplification electric circuit PCB (1.0 editions) cannot send out temporarily.
Next edition (1.1) 20 days later completes.To all the inconvenience caused. asks respectfully forgiveness!

Hi gxcnabin!
Can you mail me 2 boards for the KSA50? How do I pay you p&p?
Thank you!
