Marantz 2265 (not B model) Power Supply Rebuild

[EastPoint]

Hi folks. For rebuilding a Marantz 2265 power supply board, do any of the caps need to go up in voltage?

Also, the transistor list is:
H801 2SD330
H802 2SC1318
H803 2SC945
H804 2SD331
H805 2SC945
H806 2SC1318
H807 2SC1318

I am replacing H801 and H804 with MJE15032G. With the others, what should I be using, KSC1845 or KSC2383? Or something else?

Also, I should replace the two DS131-B double diodes with these, right? They just go in either way, correct?

I'm in the process of doing the same thing you are. I have an issue with no audio out of one channel and traced it back to the PE01 tone board, I figured I might as well do a rebuild on the power supply, phono amp, and power amps while I'm at it.

Here is the list I have come up with for the transistors in the P800 board

Symbol-----Type -----Original PN ----- Replacement PN
H801------Transistor ----2SD330 D,E ----TIP31AGOS
H802 -----Transistor ----2SC1318 P,Q,R ----KSC2383YTA
H803 -----Transistor ----2SC945 Q,R ----KSC2383YTA
H804 -----Transistor ----2SD331 C,D,E,F ----TIP31AGOS
H805 -----Transistor ----2SC945 Q,R ----KSC2383YTA
H806 -----Transistor ----2SC1318 R,S ----KSC2383YTA
H807 -----Transistor ----2SC1318 R,S -----KSC2383YTA

Could an expert here give us the merits of using the MJE15032G instead of the TIP31AGOS when replacing the 2SD330?

Thanks

I actually ended up going with the TIP41C instead of the MJE15032G since the TIP41C are cheaper and can handle more voltage.

Is more voltage handling necessary as long as it is at least as robust as the original part? At this point I'm just a parts replacer, I'm still trying to figure out how to decipher all of the transistor values as the spec sheets are a bit cryptic for a beginner.

Also, are you just doing the power supply, or are you rebuilding other boards as well? If so, I wouldn't mind comparing replacement lists if you don't mind.

I'm actually helping someone else with it, and they're just doing the power supply. You don't need the extra voltage handling, no.
