Anyone familiar with the Concord amp?
I have a Sound City Concord that has a bad power transformer
(heater shorted to frame/core and blows the fuse with all secondary connections removed).
I replaced it with a Hammond 276X and added a borrowed bias (which was easier than it sounds).
Originally, the power indicator was connected to the 245V primary tap and the amp was configured for 115V input.
I am using the the Hammond 115V input winding. The Hammond I selected (for use in the US only) does not have the 245V tap.
Question:
Can I connect the power indicator to the 115V primary connection without burning the indicator out?
It looks like it could handle the 245 volts (if you were to use the 245V taps). Also, I did not see and
specs/ratings on the indicator, although I did not remove it from the amp for an up close inspection.
I think it would work, but thought I would check with the experts.
I attached the power supply portion of the schematic as a reference.
I realize they are somewhat rare (exist in small numbers; not highly desirable).
All replies are welcome!
