Sam has always been a friend and has been helpful in several areas. He is among a group of people I try to help unconditionally.
@jonathan c and
@emorrison33 have been extremely helpful with tubes and a set of speakers, I try to never forget a favor so I would build for them as well. I suppose it could be called reciprocal altruism. I might repair an audio receiver for a neighbor and suddenly enough firewood appears to last me two winters.
Much of the banter about cardboard started when I gifted
@bcowen an amplifier. I bought a glorious piece of tiger maple yet I could not get my amp to fit into the case sideways.
I used rainbow poplar which he began referring to as cardboard. It took me a few years to find suitable tiger maple so I rebuilt his cabinet accordingly.
