Hi all. Anyone here know exactly what kind of transistors are used in the Orion XTR 2250 on the audio output end? I have one I'm trying to repair. Someone has already tried to repair it once but I think they have used the wrong transistors. They have removed all of the old ones so I have nothing to go on. I have a HCCA 250 apart as well and I can see some of those old ones.....but I'm not sure those ones would work for the 2250

 

I hope this help

 

Yes it does. Thank you. Those are the same transistors that are used in the HCCA 250 as well. I guess they used the same ones in most of the old Orion amps. I think I have already located some of each in the city too. Now if some one could just tell me where I can find the other CENU57 or MPSU57 and CENU07 or MPSU07 transistors I need, in the city, that would be excellent!. I know I can order of ebay but they are 8 US each and then I'd have to ship them.

 

I would check out Digikey. My College (The electronic DPT.) and I buy stuff all the time from there. Best part is that they work out of Vancouver.
