Heritage Audio tips their hat to certain sought-after revered British solid-state circuit designs and has them hand-built in Spain using period correct components, transformers, etc - and for relatively modest prices too!
The Heritage Audio HA73EQX2 two-channel mic preamp/d.i. with EQ is a cornerstone piece for any studio. A great piece of gear for sources captured by one or two mics, each with it's own adjustable equalizer. Frequency bands are musically-useful and beyond what many expect from a circuit derived from a classic.
