Coffman Labs “Hand-built in Portland”
Turning over the G1-A, I was struck by the complexity of the hard-wired construction. All the capacitors are oil and paper types, the switches are all 1950s-era NOS, and chokes are used in the signal path rather than resistors. Power-supply rectification is performed with the classic 5AR4 diode tube; and note the careful spacing of the signal-carrying conductors.
