Kicker SX750.1

[RJohns777]

Anyone know the part number or value of D9 and D10. They are both dual diodes soldered in series. They are in the +15 and -15 volt supplies. Once again this is a Kicker SX750.1

Thanks

If no one else answers this, post a photo of the diodes.

Hope these are okay. My camera is not the greatest.

schemes have the sx650.1 sx1250.1 and will be serving you for

[RJohns777]

Sorry fcruz, I don't understand.

[fcruz]

I have diagrams of models and sx650.1 sx1250.1 think you should serve to

[Perry Babin]

Are they defective?

If they're connected between the base of the regulator's pass transistor and ground, they're likely equal to a 15 or a 16v zener. They may have used two of them if a single diode was overheating (and possibly falling off of the board).

The user carampsguru could probably tell you definitively what they are.

[RJohns777]

Yes, they are both shorted and possibly the transistor also. I'm not going any deeper into the amp until I find out what the diodes are. No need if I can't get them.

Should I send carampsguru a message or wait for him to read the post?

fcruz, I don't know if the SX650.1 would use the same diodes. If you would send the diagram I will check it out.

Thanks to both for your time and trouble.

[Perry Babin]

I don't think that carampsguru visits often. It has taken a while for him to reply when I've sent him PMs in the past.

Did you check the connections I described to see if they were connected that way?

Do the emitters of the regulator transistors connect directly to the power supply pins of the audio op-amps?

[RJohns777]

I'm not in the shop right now. I'll check in a little while and post back.
