    Description

    Heathkit SQ-1 Square Wave Generator with Manual
    Recently restored and ready to use, in great physical condition:
    Brand new 2020 electrolytic capacitors (Nichicon/Rubycon or equivalent reputable brand purchased from Digi-Key)
    Paper capacitors have been replaced with polypropylene
    Out of spec carbon resistors have been replaced
    Line cord has been replaced with a polarized cord to ensure the hot side is switched
    Hot line is now fused
    Output level potentiometer was worn out and defective, and has been replaced with a 10-turn wirewound potentiometer (complete overkill, but the only stocked equivalent parts at Digi-Key with sufficient wattage were multi-turn wirewound; maybe the original was under-spec'd causing burn-out)
    Switch contacts, vacuum tube sockets and pins have been cleaned
    All functions are tested working, but due to its age this is being sold as-is with no warranty.  If local pickup is chosen, you may test the unit before purchasing and I will allow a refund if any function is found defective (otherwise your bid is binding).
