a 12au7 will give you far lower gains...
but then yours is a global feedback type amplifier, you can fiddle around the series feedback resistor to get lower gains...like 2k instead of 22k....
the design in a waste of triodes, a single triode stage will get you there...

probabaly the designer had thousands of tubes on stock....what was he thinking? beats me....😀
The design is suppose to be a rip off of the hetian mao circuit and supposed to be a modification of the marantz 7...
What you say makes sens that modern amps don't need such gain. This would explain why it works great on my 300B but blows the S...t out of my solid state.
The idea was to add a littl tubish sound to the solid state (for a little fun).
Maybe I should go for a simple tube buffer as mentionned and keep this for the 300B.
