Just in CTC175A have horizontal and vertical phase problem, running on variac at 90 volts. If I go over 90 volts the unit will shut down.Maybe regulation causing phase problem. We don't have service info on this one. Any help will be appreciated TIA Will Soundview Electronics ----------------------------------------------------------------------------- This Email List is accessible to the general public through search engines.
