Thin sound on H&K Tubemeister 18

[thunder100]

Dear Community-dear Tubemeister owners

I own several amps,among them a Mark V and a Tubemeister 18

Played through the same box-Tubemeister sounds thin and even if you tweak a lot with the controls-the mark V at 10 Watts will eat it for breakfast.gap is bigger at besdroom levels but still there at small Venue gig levels

This is with a Mesa Thiele EVM12L.Its better with a closed back V30(still huge gap) and most narrow gap to Mark V comes with HB's on the Tubemeister-still noticeable though.

Of course there is a huge price gap also,but has anybody an idea how to get at least close ?

If it is what it is,what would be cummunitys recommendation for Marshall style 70's clean,playable at bedroom levels and for small gigs.(The marshall cleans is not the Mark V's thing and also not my Deluxe reverb's.

Thanks

Roland
