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!

KSA50 (aaw1.2) the edition will adopt a better craft. Thickness of slab: 2MM. The copper foil is thick: 2OZ 24K gold-plating craft.
Indeed i did!
I will start building as soon as I can. CRAZY busy at work.
I took a days leave on monday to do my hobbies. 🙂

Hi!
May, so long as you pay the postage the words.
Certainly, after receiving PCB, remembered that shares your achievement with me and joyful.
