This McMartin LR1004C Limiter / Compressor came from a radio station in the USA and dates back to the 1970s. The limiter is based on a diode bridge, like the Neve 2254, and the compressor is switchable. Both sections sound awesome when crushing drum tracks – sound samples to follow
I’ve recapped the unit & will replace the power transformer so it can be used on 220 Volts. The attack & release pots are inaccessible so I’ll move them to the front panel & source some suitable knobs
Note the lovely horizontal meter – proper meters like these are an endangered species now and have become diabolically expensive
The LR1004C will be in the shop when ready
