If you only need 25W per channel, why not build a Class-A amplifier? Perhaps the F5 or F4?

yup - one pair os OK , but two pairs more adequate (SOA , low impedance spks, yukyuk)

also decrease supply voltages

Could sound strange, but I already have all the components needed for this project.

WIth appropriate supply voltages I would suggest 1 pair for 25W @ 8 ohms, 2 pair for 50W @ 8 ohms. SOA is not very good with the specified transistors and can vary between manufacturers.

Has anybody looked at this and updated it to more modern (available) parts?

It's still an awfully interesting design... we shouldn't let it wither away.

Hard to say, Jim. We traveled so fast, the doppler shift made everything we said subaudible...! (Or that's my story, and I'm sticking to it--I can neither confirm nor deny, etc, etc, etc)
