I have a orion hcca 225 poptop amp that is missing some transistors does any one have one sitting around they can take a look at and let me know what the numbers are.
I also have a HCCA225 digital reference with mismatched FETs and some burn diodes and resistors, i cannot see the lans to make bridges or install jumpers. if any one can tell me what the value of the components are here and a basic lay out of the lans.
Thanks
Sam
An externally hosted image should be here but it was not working when we last tested it.

You may want to use links for photos at this resolution.
Likely for top photo:
Top left, MPSA56 (collector to ground through 10 ohm resistor?)
Bottom left, MPSA56
Right, 2N5639
Bottom photo:
I think all of those are 1N4003 diodes.

Perry,
I think you were asking me where the collector of that transistor goes, if so yes the top left would have its collector going to ground through a 10R
