Searching for a transformer for the power board of an Equipe 2400 studio blitz Power/controller
The transformer marking (01993)... is a UK telephone number, OEP is the manufacturer. There's a high chance they will sell you a similar transformer or be able to tell you the specs from that part number.

If you are stuck I would highly recommend http://www.avantipowerrepairs.co.uk as that looks like some serious (as in, potentially dangerous) capacitance in the unit.
