Type 7 Flex cable is blue and fitted with a straight 2 pin DIN plug. This plug type was widely used in older loudspeakers but the only pedals we know which use this standard are eight older vacuum tube pedals from Electro-Harmonix all intended for powering with 12V AC. This Flex cable is available in 50cm length only.

The eight Electro-Harmonix pedals where the blue type 7 Flex should be used are:

- Hot Tubes

- Tube Zipper

- The Wiggler

- Black Finger

- LPB 2ube

- Tube EQ

- English Muff'n

- 12AY7 Mic Preamp

All eight draw less than 800mA and can be powered of a single 12V AC outlet of the AC Rider, AC10, CIOKOLATE or now discontinued AC8 where all these units have the needed blue Flex cable included.
