I would surely love to have the Heathkit TA-17, I built in '68...
No it did not work when I finished the build, ... POPS had a friend
in the (then) burgeoning electronics industry... POPS took the 'mess' (lol)
to him , $75 !!! FOR REPAIR.
Pops got Marching Orders--- the 'kit' stayed behind --- payment for services rendered
