Yamaha PC2002M

[Jenkster]

I just picked a very nice PC2002M. I was told when not in use, it spent its time in a closed road case.I listened to it briefly through a PA cabinet and it sounded awesome! I did check the DC offset with my cheap meter, see pics. Being that it was rack mounted, the footers are missing. Any suggestions on replacements would be greatly appreciated. I will also need some 1/4” to RCA cables. I plan to use it with my C-80 pre-amp eventually. Here’s some pictures. Thanks

OK, I'll bite, what are you talking about? If you posted some images, I can't see them.

Posted two images of your amplifier. The two with a meter connected to the binding posts.

What are you trying to measure? DC offset?

 

[Jenkster]

Yes, DC offset.

 

[avionic]

Need to set your meter to DC voltage instead of Amps.

Nevermind..I was not seeing the pointer on your meter dial correctly..Looked like it was pointing to the ampere side.

 

[avionic]

Offset looks good.

Utilize the inverted output of the C-80 when hooking up to the 2002. Page 4 , fig. 2 of the owners manual

Pay attention to speaker polarity in Fig. 2. One channel needs to be wired out of phase with the other.

Makes a big difference especially in the low end.

 

[Jenkster]

Will do, thanks avionic!

Just scored a mint one of these myself ...

Thanks guys, I am going to remove the covers and blow out the dust. The attenuators could also use a hit of contact cleaner. Any other preventative maintenance I should be aware of?

 

[EngineerNate]

What a beautiful beast.

 

[Jenkster]

Thank you Nate! I just removed the top cover and was pleasantly surprised at the lack of dust. I will still take the blower to it.

 

[Jenkster]

After removing the bottom cover, I see the attenuators are basically sealed. Any way to get some contact cleaner in there without surgery? If not, what is plan B, spin the crap out of them? Thanks!

You have to open them, removing the two screws that hold the body

 

[Jenkster]

Thank you amr2, I appreciate the information!

You are welcome Check the power supply (+-80V DC Board) and idling current (11mV DA and DB Boards) adjustments.

Great find, very nice condition! Do you know the year it was built?

 

[Jenkster]

I have no idea. Can you tell by the serial number which is 19032?
