In a nutshell

Avalon 737 preamp / opto-compressor still remains a reference for music studios: the best singers can be thankful for its 100% analog electronics sounding, warmth and transparency. It is used more and more on production sets, when sound dynamics becomes tricky: alternately whispered and shouted dialog, total improvisation... Nevertheless, the Avalon 737 remains a studio device: it is only AC powered, needs a line isolated from ballasts and other interferences, and is a high power consumer; the fragile vacuum tubes need a few minutes pre-heating and the device must be ventilated to drain away heat. So, it is not really fitted for outdoor production set,
