Hi All,

I am having a problem fault-finding on the PSU in my Arcam Alpha CD 6.

The section is in the picture below.

The input to the LM337 is correct at 27v.

However, the output is only 1.5v.

I have changed the regulator but it is still the same.

The supply goes to the muting relay circuit and to the -ve supply for the opamps.


Any help fault-finding gratefully received.

Andy
