We've all heard/read/seen/subscribed to, at one point or another, how brand X's 5E3 derivative is "THE BEST EVER" reinvention of the wheel, so today I'm wondering if anyone knows what the fellows at Lazy J did to justify theirs being in $3-4K range. What did they modify? Add? Looks like a voltage control option and spec'd to be able to do both 6V6 and 6L6. Anyone seen a schematic or guts?
