Good morning, I'm repairing a Singer Friden 1162.
I'm looking for the power supply schematic.
I've already worked on the EC130 and EC132, but the schematics aren't the same.
Can someone help me?
Thanks.

Hi, I will scan the schematics, I just fixed 4 x Friden 1166's. Now I am.2orking on 130's and 132. Maybe we can exchange some info.

Grazie Alex, volentieri.
Ti invierò la foto del difetto che presenta la mia 1162.
Credo sia un problema di "blanking".
L'alimentatore mi da un negativa di -4 volt anziché -6.
Non ho lo schema elettrico.
Cordiali saluti.
Antonio

bad luck.  i have the service manual for the Friden 1166 (Felix CE33) but exactly the two pages with the PSU schematics are missing :( All 4 1166's I have had no problem with the psu so i didn't need that section. I am not sure that your problem comes from the PSU even if the voltage is not exactly right. Did you test this voltages without some of the cards inserted?
