London City DEA 100 - Normal preset

Close · 72/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The London City Super DEA 100 is a 100-watt head from the Dutch maker London City, with a Plexi-style layout. Two pairs of inputs feed an ECC83 input stage with separate volumes, then a second ECC83 and a treble/middle/bass stack. An ECC83 long-tail inverter with presence drives four fixed-bias EL34s on a solid-state rectifier. It gives a thick, aggressive EL34 crunch when pushed.
