Nice build!
You should turn those Rifa PSU capacitors, they are dangerous when turned upside down. Also note the position of the safety vent, when horizontal.
Magura 🙂
Balanced B1
I cheated on mine - I am using a pair of Lundahl 1676 amorphous core transformers in a 2:1+1 configuration. Frequency response is 10 Hz to 40 kHz within 0.5 db with less than 0.2% distortion up to 22 Vrms in the secondaries. Less parts is better and I like the single-ended nature of the B1. Call me a romantic.

Well...... .If you have a single ended chassis from Burning Amp , ie all the same output devices, or if you have a bunch of matched output devices then you will like this:

look for Papa's article about discrete OP for DIY-ers ;
make simplest one , without overall feedback , with adequate local degeneration ..... and that's probably B3
judging by latest Papa's minimalistic creations .....
or - make Grey's latest preamp
Nelson Pass : The guy that gave more to the diy community than anyone else I know.
Absolute legend, gentleman and scholar.
I also hope to pay a visit some time. Or if you come to visit Australia then you're welcome in my home any time.
Nice pictures, it's good to put a face to some of the great contributors around here. You can literally see the enthusiasm and excitement each of these guys have for diy and spending time with Nelson.
