Tube rolling for Jolida 502B


I have a new Jolida 502 B amp, my first try at tubes. I'm impressed so far, does nayone have experience upgrading the stock 6550 power tubes? Suggestions and or comments appreciated. I'm driving a pair of Meadowlark Osprey's and listen mainly to blues and classic rock.

Well, I have the older 502A. It's heavily modified (see my bedroom system thru the "System" link).
I still use the stock "winged-C" 6550 tubes & like the overall sound.
The 12AX7 is a Mullard NOS & the 12AT7 is a RCA NOS.
I'm very happy w/ the sound. I like a neutral sound & I think that I'm closer to that type of sound vs. the un-modified unit.
