Replace Mark Levinson ML-2 with MJ15024/15025 need help

It looks like the ML2 spec you are quoting shows that the ML2 cannot pass it's maximum ClassA output current into a 2r0 load.
14.14Vpk & 7.07Apk into 2r0 is that 50W into 2ohm.
This is -5dBV relative to the specified 80W into 4r0.

4 Amps peak shared by eight complementary powertransistors.
That's 128Watts peak and 64watts RMS Class A power for a 2 ohms load.
Then it's going into Class AB for the remaining 80 Watts or so.

That's correct because the initial writer of this thread explained that he only could get .50 Volts at the Testpoints meaning 50/56 = 0.9 amps bias at each TO3 instead of the specified .56V which would give 1A.
3.6 Amps bias gives you a tad over 50 watts Class A at a 2 Ohm load instead of the 64 Watts with 4A. You can do the math yourself probably.
