Opened this up again to check things. OD trimmer is 22.37k from ground. The 150K resistor IS there - it is just hiding beneath the white coax in pictures. I checked the pot on the OD master and it reads 3% over 1meg when wide open and seems to be reading appropriately across it's travel. Unsolved mystery....... I may just reposition the knob on that shaft to match the clean master I'm a hack.......
You should have your cleans be just as loud if you set the input gain at noon or so.... Where do you run it?
Also, try lowering the 150K to 100K. It won't effect the volume much but may improve articulation.
Is the resistor feeding the OD trimmer a 200K? It is not visable.
Lastly, try changing your V1 tube. Maybe it is a little low on gain....
If anything, my cleans a little louder than the OD at similar settings. Of course, if you have the HRM mid trimmer set high, that will really goose the OD volume up.
What style boost is this amp?

Input gain is always past noon. Usually 1 o'clock. I'm swapping that resistor out today. I will recheck some of the voltages also. I may try trimming the whole stack back in the same proportion as it is now. I like how the tones match up - just might be passing too much juice through. As far as the boost goes - 22M resistors there. Used to have 4.7M there. If that's what you're asking. No "mega" boost or anything.
Revisited this amp heavily last week. BIG discovery. My 20k mid trimmer in HRM stack was bad. Replaced it and WOW! Now very responsive tone modification with the trimmers. It was crippled before. This even helped the over the top gain problem with the OD master. It now matches the clean level more closely on the front panel. Still tweaking....

Just a nice crack of OD, not over the top
Thanks Bob-I. Much more gain to be had with the amp. And plenty of tone to tinker with now. At these settings , the single coils bark with a nice singing sustain after. Humbucking guitars - with this amp - scream. It's now like a new amp. Much fun.
Thanks for the compliments guys!
Here's the amp playing solo guitar with humbuckers.
*point of interest* All guitars were direct box into computer while house was sleeping last night - then reamped today when I could make noise. Downside was a little time shift to nudge, so not quite as groovy as the dry tracks.

Point of interest, indeed. More dryly stated, there is NO interaction between the guitar and amplifier.

*Current take of HRM solo voice was played live and loud this p.m. Rhythm guitars - still reamped.....
I'm a hack.......
