[Heath] Heath accessory power supply PS-1175 - voltage regulator

[chrisiwata at aol.com]

The IC is long obsolete, but the NTE equivalent still exists: Use NTE953 (or ECG953).  



The internal reference voltage of the NTE equivalent may be different, so you might have
to tweak the divider resistors to revert back to the same output voltage as the original.

Greetings,

My Heath accessory power supply voltage regulator ( UA78GT4C) integrated 
circuit failed.  Does anyone still have this regulator IC?

Heath part #442-626?

Thanks,
Michael
