Hi All,

Has anyone in here ever done a repair on an Air 2000 PSU?

We have found that one of the transistors has blown and we are struggling to find a replacement.  All usual suppliers have been checked (RS / CPC / Farnell / Scattergood's), does anyone have any suggestions or is there a mod that can be done.  Its the 48v one (Im going from memory - its either 40 or 48) that has died.

Thanks
Ben

To round things off...   Managed to get a set of circuit diagrams and effect a repair on our 'Alice's power supply.  Three 'puffed up' capacitors and the +\- 18volt rail voltage reguilators (of which I have a couple spare for grabs). http://www.10radio.com/wp/ Alice is (after and MOT) back on the road doing events and looking forward to the Taunton Flower Show - a splendid occassion https://tauntonfs.co.uk/ 
Thanks to all who helped   √
Best wishes,
