: On the side of the three gang tuning capacitor on the above set two of the gangs have single terminals at the bottom and top between which is a straight wire. The leads from the band selection switch to the grids of the RF Amp and Det/Osc tubes connect to the bottom terminals respectively and the top terminals connect to the grid caps of the tubes. Is the wire special resistive wire or was this done for ease of assembly? Why weren't the leads from the band switch run directly to the grids instead of the bottom terminals and then off the top terminals. I forgot to add that there is no connection from the terminals to the condensors, they appear to be just connection points. Anybody can explain this I'd appreciate it. PL
