I use hybrid bridge with two 6AX4GT damper diodes. Choke input design using same chokes as you spec'ed. 4HY-30uF-4HY-to 2x Cree diode to 2x 100uF (one cree diode & one 100uF for each channel. I would then feed each channel front end with same 1.5HY choke and a 22uf capacitor. Unless you have a very high current demand front end 22uf is plenty of filtering.
Capacitor sizes simulate well for fast recovery without voltage overshoot, yet low noise (assuming 150-200ma for total average current draw). The Cree diode & 100 uf for each channel isolates the last capacitor from the other channel. Use a low DCR power transformer of about 10-20 ohms on B+ winding.
