Title: Sansui AU-X1
Post by: winkle on September 02, 2017, 03:08:26 PM
Amp won't power to full capacity. Power light starts flashes but won't go solid, I was thinking power switch itself because sometimes I'll press power and light starts flashing and other times light wont even come on more often the latter... [ the indicator will flash to notify you of an abnormal condition ]

What voltages are you seeing in TP1-4 from the power supply?
