I had to remove the psu on my 11/44 as there was no 'dc ok' light showing when switched on, I have stripped the psu and found one of the large diodes have failed. This is a Unitrode item marked as "USD 5111F " I am trying to locate some replacements , (I was going to replace all four while it is apart) I am not having much luck finding a spec sheet or data for this diode, Farnell, RS, and such have no reference. Can anyone possibly help to identify the spec .Perhaps an old Unitrode catalogue or such? so I can source the correct equivalent diodes. It has 1/4 unf stud mount, with aprox 4 Inch rubber sheathed tail and 3/16 hole in the end lug.
thanks
