I have two of these models, the LV poser supply is mounted with pcb face to the rear. these have
a fan mounted on a bracket. the 6 transistor heat sink faces to the front, the fan for cooling. there
is a separate metal plate (a bit bigger than the lv pcb) with cutout for the fan air stream. the back
cover is sheet metal, plenty of punched air holes. As I just downloaded a later vintage 7603 manual,
it shows a different assembly for when the 7603 has a fan. What I have is physically identical to the
LV power supplies as used on the 7613, 7623, and 7633. The side cover plates have very few holes,
as the fan will be drawing air up from the bottom plate.

Anyone else have this, what vintage manual shows this?
I am in need of one of these lv ps assembly, as least that plate.

As far as I know this was only available as a mod kit.
You can find the kit instructions here

Hey H?kan, was there a kit like that for the 7313, or did they all come with a fan? Mine has one.

Hello zenith5106, that's IT, thanks for the link.

The part I am looking for the #19 "air baffle" in the parts list.

Thanks, Stan KO6YB

Dave,
As far as I could find there was no such kit for 7313.
However there was an internal mod effective from SN B260000 which added
the the same fan assembly as those used on the other 76xx storage mainframes.
So after that SN 7313 had fan as standard and before it didn't have a fan.

Thanks, H?kan. I don't remember my S/N but I guess it's a late one.

That fan is really quiet.

I think a friend of mine has it but it has been raped. I can ask. Are you modifying it to use the fan or what here ? Or is it missing or the PCB cracked or whatever ?

If you need a working one forget about this one, first it went bad and then got used as a donor.

Adopted a parts 7603. I have the lv pcb + heat sink / transistors in a box, bad but repairable. It is missing one of the vertical supports (need to look at it again). Fan is there hanging out the back of the scope by the wires. But the flat plate is missing.
