Having built one of the "other guys" hybrid tube/ss amps as a gift for my son-in-law got me thinking about similar A/B comparisons the other posters here are looking for/at.
A PCB build, and obviously not the full-tube Crack experience, it includes jumpers that allow switching between CCS and resistor plate loads.
Paul, could the Speedball board be retooled to include the resistors and jumpers? I realize the 3k wire wounds need to dissipate a lot of heat - maybe bottom mounted to get them close to the vents?
Sure, the adventurous, and well heeled, DIYr could design and procure a board or two and give it a try; but such a board seems like it would still fit the BH model allowing an upgrade path with the bonus of easily reverting to the "OG" sound when some extra sugar was called for, or desired.
This is just me thinking aloud, let me know what I'm missing...
Thanks as always, Karl
