Hi,

I need to ID a diode. It is in the regulation circuit of an old 28v Power Supply.

http://wallyheider.com/wordpress/201...udio-recorder/

Markings are Z104 (twice) and CDC.

There are other diodes on the board in the 1N4001 case style/size, but this one is slightly longer and thinner and has a black shiny coating, not matt.



There is a schematic on the Interweb for this machine, but this supply does not correspond to that circuit.



Cheers,


Gareth.

The old Lambda power supplies used a FBM-Z104 6.2V Reference diode.
Make sense?




Supply still not working with new 6.2v zener.
Do you know of any schematics for this? The PCB is Lambda HAL-01-006.



Cheers,


Gareth.


Oops, I'm an eejit, there are 2 Remote Sense connections on the PSU output that are required to be connected, the PSU is now running fine.


Cheers,


Gareth.
