No, I own amps and old mixers from the 70's that had the same type of led meters. An Oz built 20 channel Jands JM6 and a 12 channel Jands JM5. The old Jands J600 power amps also had led meters, I bought one new in 1978, however the LEDs are not very accurate LOL. Just a side note, Jands was a company set up in the very late 1960's to make PA gear, on of the founders was the late
Bruce Jackson who was very enervative and way ahead of his time. Jands today mainly make lighting gear.
