Hello all someone asked me to build a "mini" major with 2 KT88's, but I am having trouble sourcing a schematic that is fully legible. Anyone have a clear one. My main questions are regarding the V2b cathode resistor values and the Bias feed resistor values, 82k?

Lastly, I was asked to install a PPIMV. It seems the "rich II" style seems like the best option. Any thoughts, advice?

I plan to use a JTM 45/100 PT to get 560+ on the plates. I will use a 100 watt OT with 40% taps for the ultra-linear connections.

Thanks!

The bias splitters read 68k and the v2b cathode resistors are 2k7 in series with 100k

Here is the build:

Beatiful! (although I don't like the sound of metal oxide resistors, even in the power supply)

Amp is done....

Here you go:

Cheers!
That is a great sounding amp!

Just curious what brand and spec transformers you went with? Amp looks and sounds awesome.
