This XL-100 uses modern-day channel buttons, but still uses four 300-ohm screw terminals (2 for VHF and 2 for UHF). I thought that was pretty strange.

fairly common sets - i think i have passed over 3 at estate sales this past year - 2 black ones and a white set - not lucky enough to find a red one
