The Norelco/Phillips EL 6911 Studio Echo Machine c.1961

Good lord take a look at this thing.  The Phillips EL 6911 echo machine.  Distributed in the US by Norelco, who also distro’d AKG mics in the 1960s.  You can find much more information on this monster at this website.  These still turn up on eBay from time to time.

  1. EL in the Philips typenumbers is probably a short for ELA, the Philips division, that created, produced and sold electroacoustic devices.
    The division was named Philips Electro Akoestiek.
    There was still a successor in the 1978 catalogue for the echo machine, model LBC7100/00, is called a delay machine and intended for railway stations a.s.o., to improve speech intelligibility.
    The mechanics look the same. The amp is probably transistorized in that era.

  2. Does anyone have the terminal block wiring info for the inputs
    and outputs on a Phillips EL6911 ? I’m restoring one here in my
    shop, and any schematic info would help reduce the amount of
    reverse engineering I’ll have to do.
