QX-8000 Recap

Hello Everyone,
I started working on a QX-8000 and I was wondering if I could get the experts to look over my cap/transistor list. I added what I think are the correct part numbers for the caps but I wanted to get confirmation before I order. Also, I don't know which transistors I should replace and what the correct replacements should be. I don't want to screw this up and make it into a long complicated repair. Thanks for any help that you can give. Todd

Mark,
I started a new thread because I didn't want to mix up the parts and repairs between the QX-8000 and the QX-9900 that I am working on. I wanted to get the cap/transistor lists for both units completed before I ordered parts from Mouser.

Todd
 
The power amp boards on these are a PIA due to the gazillion wire wrapped connections and not a lot of wiggle-room...
 
Just waiting for MTF to review the list and instruct me on witch components to replace. I don't want to screw this up so I will wait for his expert advice.

Todd
 
Note: those are two of the most heavily populated receivers Pioneer made, with a LOT of circuits I have not previously reverse engineered.

I have PROMISED certain deadlines to people for their equipment, and I have INFLEXIBLE deadlines for other non-audio ESSENTIAL Political work (literally 1000's of people are DIRECTLY depending upon my work) bearing down on me, making the months of February and March REAL ULCER GENERATORS.

Don't really expect me to start, no less do, two extra huge units before April. They could be the straw that broke the camel's back...

Oh, and the tuners.... hands off... they will take much additional work beyond that and most things should NOT be changed. Some of the lists you are are more populated than the recap lists, they are the replacement lists for when circuits get blown up. Recap assumes a working unit.
 
Mark,
This is my hobby so I don't have a strict time line. It is no rush on getting the list checked out. Whenever you find the time to look at them would be great. You are doing me a great favor so please don't stress over my stuff.

Thanks
Todd
 
Hello everbody,

I was working on the QX-8000 and in the misc parts of the SM I noticed the caps for C1, C2,C3,C4 are listed as: 2200 35v c52-077-0. Does anybody know what would be the recommended replacement for them? Also, C13 is 4700 63v ach-007-0. Most other posts recommend UPW for the CEA caps but I can't find anything about these other type of caps.

Thanks
Todd
