Used in many Mesa-Boogie and Crate models in the channel switching circuit. 100dB dynamic range, fast response (2.5ms turn-on), very high dark resistance (50 M Ohm). Light resistance 200 Ohms at 20mA LED current. See datasheet. Part # VTL5C1 $4.95 Click on photo for larger view 10-Conductor Ribbon Cable 3' Used to interconnect circuit boards in a variety of amps.

• 3 inches long • 10 conductors set at 0.1 inch spacing - complete cable is 1 inch wide • Bare wire termination for soldering to PC board at 0.1' hole spacing - no connectors • May be easily cut with an X-Acto knife to make a cable of fewer than 10 conductors. • Not recommended for use in the Fender Hot Rod Deluxe / Deville or Blues Deluxe / Deville.

The ribbon cables used in those amps have ribbon cables with conductors set at 0.156' spacing - this cable is too narrow for that application.
