The treble-cut cap will affect the bass end very little.

You mentioned that the speaker had been reconed. Does the cone move in and out easily with no rubbing? If the new cone were too stiff, it could impair the bass.

If the coupling cap feeding the grid of the output tube were too low in value, it could reduce the bass without affecting treble. (A misplaced decimal point will change a value 10X.)

Seems to be moving freely and properly, as far as I can tell. Is there a break-in period for speakers, like with a new car?

I'll check the coupling cap as well. That value was actually marked on the schematic (penciled in), but I'll double check to make sure the anonymous repairman wrote in the correct value.

Thanks,

Tim
