Gain stage EAR 834 : resistors and tubes

Hi ! I'm testing for the first time my EAR 834 clone, following as close as possible the Skunkie's layout. I'm testing with cheap tubes : x2 12AX7 JJ and x1 Ruby 12AX7. Very satisfy with bass reponse, high, with all, wicked !!! but it's clipping RED on my vu-meter (I diy vu-meter on my ADC Sound Shaper EQ).

Could we talk about gain stage there ? Please, give me your science, advises, references etc. Just, I dont want volume pot ;)

I know tubes have differents gains. But resistors control the gain. Which value should I change for resistors ?

Thanks Everyone !

I'm really not understanding what you're trying to do cuz from you posts it appears like it sounds fine. You're just wanting to get some VU meters reading in the center or something?

ok interesting, what is ruin the bass response ? pot or adding some resistance between the pre-out and this 220k, or both ? i dont see what you mean by voltage divider, i take a look on google. If i'm using this pot at 5% of his capacity, maybe it's fine for keeping safe sound quality ? I dont need more than 5-10% less gain, ok sometimes more maybe,.. That's working, but I want to choose cleanest method for signal... Here is a simple stereo pot.
