Advice on what to build... B1/F5?

Forget it 🙂 too much reading today.

1943/5200 as the multiple pair output stage should be very good for a low rail voltage ClassA amplifier.

It's supply rails above ~+-55Vdc that stress the poor HV SOA of the 1943/5200.

Should be good for f5 then?

and F5t and many other ClassA amplifiers.

Lot's of silicon on big heatsink always looks good for SOA.

F-6 is next on my build schedule. Whichever Pass amp you build, you will find it will better your previous amplifiers just like the BA-3 Preamp bettered your other preamps. You are in for a treat.🙂

Will be fun if a solid state amp after all will better my DIY Atma-Sphere OTL amps but I doubt it. That said I'll replace my Firstwatt J2 clone with the F6 to see where it all ends. And of course I've to try one the SIT amps too.
I'll also build the B1 and Pearl 2 and see how it performs against my RTP3D clone.

Why? Because you've more fun here at the NP forum. 🙂
