Vintage Synth Repair

Sorry Matt, I think you mis understood.  His firm's instruction is not to
use lead free solder. In other words the instruction is to use lead/tin
solder on all military contracts.   However I was interested to read about
Uranium being present in Lead/tin solder.    Best regards John.
