UREI LA-4 Experiments
PART-1: Built-in mic preamp
ã 2000 ~ 2004 by Eddie Ciletti
The LA-4 above features a SOWTER mic input transformer followed by an improved version of the Trident Series 80 style mic preamp. As of July 2004, there are four in existence. The FULL modification - improved opamps, modified RATIO switch, 3-speed response time and Mic Preamp with Phantom Power costs $1000 with transformer. This would be the modification price to your unit.
