Hi listers, I worked a Telechron much later and I believe the Worcester plant was at 2 Main Street. I remember seeing a picture of vacuum tubes produced at Warrren Telechron during the war. War contracts were quite lucrative and there was lots of money to be made if you had the equipment and space. Henry Warren started off built synchronizers for the grid. This branched out into the production of synchronous motors and their related clocks and timers. They were eventually bought out by the folks who bring good things to life ...... General Electric. The Worcester building was eventually closed and all production was moved to Ashland, MA. Jon Normandin Burlington, Vermont. **************Create a Home Theater Like the Pros.
