- Woo Audio WA33 Gen 2 owners comparing tubes
- Worth noticing
- Combination profiles weight the power tube at 55%, rectifier at 30%, and driver at 15%; the site says they are expectations, not measurements.
Field notes
The matrix blends tube-family profiles with stated weights of 55% power, 30% rectifier, and 15% driver, and lets a visitor load a combination into the roll panel. Its bench tools expose adjustable model inputs for a 2A3 plate curve and 6C45 driver stage; the page identifies the signal-path diagram as representative rather than Woo Audio's schematic. Fit details are still being confirmed.
