Having problems with the LM350T regulators IC's . I have made sure that the fastening screws are centered
and still only getting IC2 21.9 V IN - 0V OUT
                                              IC3 24.8 IN  -  2.8V OUT
                                              IC4  21.9 IN  - 0V OUT
                                              IC5 24.8  IN - 2.8V OUT
IC1 WORKS AND WAS TRIMMED TO 48.5 (different IC)

DC OUTS  - 16 SHOWS -2.8      +16 SHOWS +2.8
V#2'S are identical.

Stumped !
It would appear that all 4 IC;s that are LM350Ts are not functioning.
They are all getting proper voltage.  but what is coming out is 14 v low.

Note to self
Maybe you should check the 243 ohm  and 2K43 resistors at the voltage regulators
