This 1280 has been serviced before, the previous tech did a dubious and lazy mod to the protection circuit which I'll be showing here a little later. We'll start with the preamp boards.

And after! 10 caps and 2 transistors were replaced. The 4.7uF input caps were replaced with a Panasonic polypropylene as space allowed it.

Next, the tone amp board:

And after! 36 caps and 4 transistors were replaced here, this is a little more than normal as I'm replacing the mylar caps as well with WIMA and Evox/Rifa polypropylene caps.

More coming soon!
 
Thanks guys!

Today was a good day, got 5 boards done. First up is the function board, this one has just 2 caps on it:

And after. (this new camera's image quality is amazing. :bowdown:)

Next up, the filter amp board. The two 10uF caps were already replaced with Nichicon VR caps, but they're not the ideal replacement.

And after! 8 caps and 2 transistors to replace on this board. Also cleaned the filter switches thoroughly but I forgot to get photos.

Now we go to the meter amp board, just 4 caps here:

And after!

And last in the line of the boards on the bottom, the phono amp board.

And after! 14 caps and 10 transistors were replaced here. Using Panasonic ECQ and Wima FKP for the small mylar caps.

And that finishes up the boards on the bottom, let's flip it over and start with the right power amp board.

An unpleasant surprise greeted me when I flipped the board over, the previous tech destroyed part of a trace leading to the offset pot when they replaced it, and the jumper they put in is a little remiss. Not too difficult to solve, just annoying.

I bypassed the broken trace completely and soldered some small gauge solid core wire to a solder joint further up the trace. Makes for a much cleaner look.

The 2SA979 dual transistor I replaced with a 1% matched pair of KSA992 put face to face and heatshrinked together. I've found that the 979 tends to become leaky, causing the offset to jump around a lot and make it hard to dial in, even with a multi-turn pot. The 1uF input cap was also upgraded with a Panasonic polypropylene.

And after! 9 caps, 3 transistors and both trim pots were replaced. The molex pins were also cleaned with an eraser to a nice shiny surface.

Getting close! I have one more amp board to do along with the protection and power supply boards. Then the filter caps and cleaning the chassis internally and we'll be ready to fire her up!

And finally, the last 3 boards.

First up, the left channel power amp board:

gWkiV5t.jpg


And after! 9 caps, 3 transistors and both trim pots were replaced, same as the right channel. All the traces were intact on this one though, no wiring needed! The molex pins were also cleaned.

Next, the power supply. This had been recapped before, a weird mix of Nichicon, Jamicon and LCC caps. The relay was also replaced with (amazingly) the correct replacement.

While I was replacing the relay (just so everything is new), I noticed this. For those wondering, that is pin 1, which is the 120V AC in to the soft start circuit. This thing did work when I got it, so it must have been just barely hanging on and me moving the board to get to the back broke it loose.

Much better!

And after! 16 caps, 7 transistors, 7 diodes and the relay were replaced. An extra heatsink was added to Q5 as well.

And finally, the protection board. One of the concerns brought up by suitekids when he sent this to me was the fact that there was no protection delay at all and would thump his speakers pretty hard. Anybody see what's wrong in this photo?

Don't worry guys, this is totally a good repair, I saw this done once on TV. :rolleyes:

DDyXkQp.jpg


And after, looks a lot better! I found another interesting thing, C16 (next to the 22uF) was replaced with a 10uF rather than a 33uF. Not sure if a 10uF was on the board originally and they replaced it with the same, but the other 1280 I did awhile back had a 33uF there, so I'm not sure. I replaced it with a 33uF. 6 caps, 2 transistors and the relay were replaced.

And that finishes the boards! I'll be moving on to the filter caps shortly.

Thanks! I don't want to crap on your thread, but may be interested in your crate at some point (as I've got a SX-1250 that, although it's been partially restored, is having it's ass kicked by a SX-680).
 
And lastly, the filter caps. These were upgraded from 15000uF to 22000uF.

Before:

And after! I also cleaned up the transformer and chassis under the filter caps.

Powered it up on DBT, checked bias adjustment and offset, everything checked out so set it back to 0 and fired it up on line power.

Set the bias and offset, hooked up the speakers and source, and WOW! :eek2: Easily the best sounding 1280 I've ever heard. This is the first one I've done with the polypropylene signal path cap upgrade, and the difference is amazing. I'll be posting a video here shortly in which I tried to capture the incredible soundstaging and clarity of this thing. It isn't quite as good as it is in person, but it's close. Stay tuned.
 
Good job other than, I see original ecaps in the tuner? Pls do not be reluctant to change them, changing ecaps in this tuner, it will not take it out of alignment. Time to order some more Nichicon UKL? :)
Just a bit of a PITA to deal with the dial string, making sure it does not unravel, as that is a bitch to deal with. take notes on winding procedure if it happens to unravel, where the dial pointer is at, etc.
Makes you wonder why pioneer would not make these notes available.
turn var cap to the position to access the screw that holds the blk plastic wheel on the var cap shaft, tape up the string around the wheel, so it will not unravel and lose tension, remove set aside with tension on the wheel, if possible. change ecaps, reverse assembly. test. bobs your uncle.
 
I can think of a small improvement, put 1uF/100V film caps across each PS Big ecap. This helps filter out higher freq noise.
use leaded types like the Panasonic and solder/crimp to ring terminals, simple mod.

Haven't received the parts yet, still waiting. With Christmas coming it's possible I won't receive them until next week.

I personally have never been entirely convinced that bypass caps are an improvement. I tried it on a SA-9500II and found that the sound became unbearably harsh, it was very hard to listen to for any length of time. However, I have improved a lot of stuff in the system since then, my source, cables and speakers are all MUCH better than what I had then, so it's possible they'll be an improvement now. I'm going to be experimenting on my SPEC-2 with and without bypass caps and see if there is an audible improvement or not.
 
Finally got this uploaded. It's not quite as good as it sounds in person, but it's close! Be sure that's in 1080p quality, the embedded player sometimes puts it into 480p.

 
And the requested song by suitekids, Pink Floyd's Money! In case anyone is wondering, this is as it was recorded from the speakers, no post processing of any kind.

 
The tuner is done!

Before:

And after!

Looks like we got lucky as well, this tuner seems to have never been touched. Fired it up, adjusted a couple things, tuned to a local station and:

Seems to be bang on, dial is perfect, center tuning off station is good and it's picking up stations that normally don't come in well. Whew!

Edit: Added tuner list and BOM to the main list in the first post.

Beauty shots! Got the faceplate and knobs cleaned and shined up, came out pretty well. Protect your keyboard from drool, you have been warned. :D For the geeky camera guys, these shots were taken with a Sony DSC-RX100 with very minor post processing to tone down some glare. Everything else is as shot.

And that finishes this restoration! It will be on its way back to @suitekids soon, just have to get it packed back up.
 
Wow, nice rebuild. I did a couple 1280s years ago, remember them being a bit of a pain to work on. But they sure do sound good and look amazing when they're done.
