PIONEER SX-1250--REPAIR SERVICE--FULL CLEANUP AND ADJUSTMENT--PERFORMANCE CHECK

Description

NOTICE!!!!!  Please read the entire text of the listing.  This is a service listing for the specific model noted.  The pictures are examples and are not for sale.
So you have the good fortune to have a Pioneer SX-1250.
You know that the 1250 is a really great receiver, after all they have become very valuable, but yours is just not performing as well as it should.
It could have overt defects, or it could just be tired.....noisy, dull sounding, hard to tune.....that sort of thing.
You would really like to get it serviced, but it is all just confusing.
You don't know who should service it or what they should do.
I can tell you, it should be serviced by somebody who knows the piece inside and out.
That would be me, as I have worked on the 1250 since it was introduced.
My company was under contract with Pioneer when these first came out.
We did the in box defectives.
So I know the piece very well.
As far as what the approach should be......here is a good idea, get it all cleaned up and adjusted, check everything and when that is done, it is either up and going, or we are very clear on what needs to be done.
So that is what this listing is all about, the non confusing approach to SX-1250 service.
1
Clean it up.
You can't work on a dirty unit so the first thing to do is to blow out all the dirt, or more severe cleaning if needed.
Next, the switches, controls, and tuning capacitor are carefully cleaned and deoxidized.
A lot of problems are solved by thorough cleaning.
2
Alignments.
If the baby is electronically sound, meaning it comes up and plays, it is necessary to check power supply voltages, amplifier bias, and tuner alignment.
Adjustments are made where necessary.
3
Performance verification.
At this point in the process, you can tell how close the unit is to spec performance.
These would include amplifier power and distortion, tuner performance, and signal to noise.
The unit is also inspected for any parts or conditions that are marginal or likely to fail.
The final step here is to run the unit for a day or two to confirm that it plays well over time and has no intermittent issues.
When all of this is complete, sometimes we are done and it can go back onto your shelf.
If there are outright defects or any other recommendations, I will contact you and explain your options in detail.
You may then decide how to proceed.
STANDARD PACKING
I pack a lot of stuff.
I have good success with my packing and encourage you to do it this way.
First is the bubble wrap.
Use the larger bubble in 24 inch widths.
Wrap the unit four times, turning it each time so you get the long way and then the short way.
This gives you good overlap.
Tape it tightly.
It should be like a cocoon.
The unit then goes into the inner box, fill voids with additional bubble wrap or peanuts. The inner box goes into the outer box with packing peanuts in between.
Be sure to put in enough peanuts so the inner box will not move around in transit. Tape well, insure the package.
Ship prepaid to:
