Discrete linear audio power amplifier schematic KENWOOD KA-7300

[strawberry]

Is this good amplifier schematic?

[tatus1969]

its a classic design from 1990s or earlier, served well until it died and was replaced by an UcD amp.

What are your objectives?
The amp schematic you provided should work fine.
Do you want something just to copy?
How much power do you need?
What are your skills in making such a circuit?  A +/- 60v, or 120v total supply can do some damage and possible harm if you are not careful.
Do you have just a volt meter, or, do you have access to a scope?
What kind of sound quality are you expecting?

This amp still has an op-amp IC in it, so, it's not really considered all discrete.

To replace/repair KENWOOD KA-7200 power amplifier
supply rails +/-50V

Is it necessary to equalize currents between both differential amplifiers?
