What is your goal?
I've seen & listened to these amps several times.
What a monster!
Except for changing parts, all I can think of is changing the operation point of the output stage by re-bias them, and also adjusting to a proper HT. However with such a high voltage power supplies, I think it'd be very hard to deal with....
Here is an interesting article about this amp by Joe Roberts, digested from SoundPractices. |
