SOURCE: Yamaha P4500 service manual

one thing for sure Yamaha will not turn their back on their customers for support. What they normally say is that you contact your nearest service center for assistance. But you know you have a very good chance of getting a copy of the service manual since this is a very old model. i have the same amp being used in our church and yamaha service Japan has sent me by postal mail. technology nowadays is much different so maybe they can even send you in pdf format.

Write them by postal mail :
Yamaha Corporation
A/V PA Service Department
10-1, Nakazawa-cho, Hamamatsu, 430-8650 Japan.

simply tell them you need the manual and you are doing the servicing on your own. No one in your area can help you with it.

anyway, what is wrong with your P4500, it's a good amp but sensitive. very good design, hard to troubleshoot if you're not familiar with Yamaha amps. The main parts you can not replace buying from a local store though you may get the same part numbers specially power/driver transistors. it always comes in complementary pair critically matched by tthe factory. i tell you don't get the replacement anywere but Yamaha only. Yamaha have made to order power transistors tailor made for this Amp. you'll find the same transistor number outside but when you plug the unit, it wont last and worst it bursts !!! be carefull. Very hard to scan a copy of manual for you, but if you dont get a reply from Japan you can email me and we'll try to find a way to send you a soft copy.

I was getting super frustrated with my camera too, my huband is a genious.. he just flipped the mode to the one that shows a usb cable on it and it worked. Maybe this is all you need to do as well? Hth

The above solution only gives the specs.
Go into the Navigin site. Click support, then under topic select downloads. You should then get the option of the user manual for the 12er and 22er. Select your language and it should download the complete instructions file, all 58 pages of them
Hope this helps as I have had a really hard time finding this.
