A Dynaco ST-70 uses two predominate fastener sizes (ignoring the threaded bias potentiometers) in kit-built units; 4-40 for all chassis assembly and 8-32 for transformer-to-chassis attachment. We offer a pre-packaged fastener set using the same stainless steel, slotted drive, pan head-style machine screw as used by Dynaco in OEM kit equipment and Kep nuts that replace the OEM individual lock washer and nut.
