One thing many overlook; the small driver tubes. They contribute more than one might think.I bought some cryoed tubes and they were expensive / but worth it.
I just sold my pair and with the Music Tech upgrades / mods they only brought 2300.---One thing to have checked is the biassing resistors. They do go out. My 8's and 5's had this same problem. Tubes lasted for me around 3 years.
