This is the perfect Speaker Terminal Block for our Dyna amplifier products; it fits the ST-70 (and other Dynaco amplifiers) like they were made for it- no holes to drill – just bolt it right on with the supplied fasteners. These Terminal Blocks will protect the Fuse Body and the Power Switch from being bumped & damaged because the terminal block extends past both the power switch and the fuse body.

Note that the individual terminals are separated by a molded-in barrier. This prevents stray wire strands from shorting across speaker terminals, prevents spade terminals from touching and they accept screw-in banana panel jacks to make interfacing with speakers a breeze. These terminal blocks will bolt right up to Dynaco Mark II, III and IV mono block amplifiers, as well as some HeathKit, Marantz and Harmon Kardon tube amplifiers
