AAAANNNNNNNNNDDDDD WE'RE BACK!
Thanks to the generosity of AK member
Tonebells (Tony) I have on the way to me a power amp board from a Marantz 2216.
As many of you may know the 2216 and 2215b are almost identical on the inside.
I have gone through the service manual for both of these receivers looking at the components list for the P700 board and performed a part-for-part comparison.
There are a total of 12, or possibly 14, differences. I realize that often there is a difference in the actual parts on the board and those noted in the service manual. The list that follows has been generated solely from the parst noted in the service manuals. (if you know that any of the listed parts are in fact manual errors please advise me of such -- Thanks.)
2216 // 2215b
R705
resistor 150Ω +/- 5% .25W // resistor 200
Ω +/- 5% .25W
R706 resistor 150
Ω +/- 5% .25W // resistor 200Ω +/- 5% .25W
R735 resistor 0.22
Ω +/- 10% 3W // resistor 0.47Ω +/- 10% 2W
R736
resistor 0.22Ω +/- 10% 3W // resistor 0.47
Ω +/- 10% 2W
R737
resistor 0.22Ω +/- 10% 3W // resistor 0.47Ω +/- 10% 2W
R738
resistor 0.22
Ω +/- 10% 3W // resistor 0.47Ω +/- 10% 2W
R741 resistor 2.2
Ω +/- 10% .5W // resistor 22Ω +/- 10% .5W
R742 resistor 2.2
Ω +/- 10% .5W // resistor 22Ω +/- 10% .5W
R745 resistor 1kΩ +/- 10% .5W // resistor 220Ω +/- 10%.5W
R746 resistor 1kΩ +/- 10% .5W // resistor 220Ω +/- 10%.5W
C721 Electrolytic Capacitor 3300μF 35v // Electrolytic Capacitor 2200μF 35v
C722 Electrolytic Capacitor 3300μF 35v // Electrolytic Capacitor 2200μF 35v
C719 ceramic capacitor 0.1μF +/- 10% // film capacitor 0.1μF +/- 10%
C720 ceramic capacitor 0.1μF +/- 10% // film capacitor 0.1μF +/- 10%
Disregard the colours: just an artifact of cutting and pasting.
As for C719 & C720 the values are the same, but the 2216 has Ceramic caps and the 2215b has film caps - not sure if this makes a difference.
I have all of the caps, as I was planning to do a recap before I broke the PCB so it is just the resistors I need.
As I haven't done a lot of this stuff I'm not sure if there is a difference in resistor quality. Would generic resistors from RadioShack/The Source be ok of are there better quality resistors that I should be using?
EDIT: Damned board formatting screwed up my chart 2216 is first 2215b is after the '// '
