Like they should...OP... That's what all the older Klipsch used as a standard, Mac, and Marantz... It was just the way it was.. Everything else was kinda in second so to speak.. HS Scott, Fisher, Heath, Dynaco, good stuff.
The standard was Mac, Marantz, Garrard, Thoren, Klipsch, JBL, Jensen, Altec. The true time of tubes.. there was no SS.. Just starting circuit boards. Everything was point to point or straight wire (turret board) point to point.
I was a Jensen Imperial and Mac guy at 15.. LOL long time ago..
