I finally got my TS11 racked this morning and after a good cleaning

Looks like the H744 supply is not working. Anyone know about these?
Are they easy to fix? Should I just pull it, find a schematic and
start
probing?
It's used in various devices, from KL10s to 11/34s so the schematic
shouldn't be hard to find, and yes, they're fairly easy to work on.
It's a fairly simple circuit based on a 723 regulator chip.
I think I do have a spare, but I doubt if you want to pay transatlantic
shipping :-) H7440 and H7441 are very similar (different circuits,
same purpose).
