Default Farnell L30 PSU


I have one of these PSUs and it isn't performing quite right. Having had a look inside, I'm not surprised, as the caps and resistors look original and it appears to be late 1960's or very early 1970's (all the transistors are OCxx series).

I am going to replace the electrolytics and any off-value resistors, but I would like to know how to set it up properly. Has anybody got a circuit diagram, or better yet, a full manual for one of these? The one I found on this site relates to a "newer" (relatively) model with 2N transistors.
