- In this video, I complete a few more modifications to the amplifier boards, pull and re-work all boards from the front end, restore the front-end cosmetically, perform some basic testing, and ask for much needed help from the viewers!

Ohh, much much better video , no more camera shaking, details filmed well too, very enjoyable to watch your video on your channel. Thanks again Greeting from Sweden.
Another outstanding video. Your attention to detail is amazing. Keep up the great work.
I love your work, please keep it up. It's hard to find your kinda service.
Amazing job, congrats !
Wow! You make awesome videos on this grail. Im no tech but of all youtube repair videos of the 1980, youre the most fun to watch..
Thanks @cheng96818
That looks like a beast and alot of work !
Great work. Thanks 👍
Thank you too!
Meticulous work. Must’ve taken ages
I just subscribed to your channel and like your work. I wish I could find a tech to service my Pioneer SA 9800.
Hi Joe. I’m glad you joined. It’s certainly a labor of love for anyone doing this so I’m sure it’s hard finding help. Of course It’s usually not worth it to ship these big items either. What area are you in?
Did you make it to chapter 4?
What did use for stain/finish on the wood case? Also, what grit sandpaper did you use for that process?
Don't do it the way he did, prep the wood, careful if it's veneer,or you'll sand through to the plywood! & apply a Danish oil with a cotton rag / old t shirt, dont use a paintbrush! Even better is a nylon stocking stuffed with cheesecloth, wipe it on sparingly, steel wool with 0000 steel wool,don'tbe too aggressive, just remove the sheen, wipe off residue and repeat, wipe with a tack rag in between , the color appears to be a teak or cherry . 60% mahogany and 40% cherry mix would look great .hard to get oil stain anymore thanks to the democrats ,so unfortunately you'll never get a really nice finish, but that's what it's all about now isn't it , mediocrity, don't strive for excellence. Ps if you need to sand, sand lightly with 150 - 180 remove dust with a large paintbrush, wipe with a damp cotton rag/ old t-shirt, cotton not synthetic lightly sand again with 220 & then follow steps above
I have a sx1980 that could use a full restore like what you’ve done here. Where are you located ?
I’m in MN, 55129.
One of the things that I think technicians like you don't take into account is that a manufacturer will use certain capacitors to get a certain sound that he is aiming for.
That means he may have tried many types of capacitors with many hours of listening until he decided what to put.
And just because you put something with the same values and the wave looks good on the oscilloscope doesn't mean it sounds the same.
This is audio equipment not a TV or a refrigerator. Therefore, when you decide to put something that has the same similar values but is produced by a different manufacturer, you should understand that it can affect the character of the sound.
That may be true, but 45 year old caps should be replaced if you want a piece of equipment to last another 45 years. And I can only use the components I have available to me.
@@dualityrepair4770 It is okay to make the equipment more stable and durable for years to come
But if a certain component such as a capacitor or diode is measured properly
I think it's better to leave them as they are. Especially if they are related to the audio signal. Because if you start replacing everything like this, you might change the original design of the device.
And it can damage the magic of the sound that the designer aimed for.
Even if from an electronic point of view everything is measured according to the electircal schem. In terms of sound, this could be a change for the worse.
nice work. However, I was VERY surprised that you did not recognize the tantalum capacitors!....a bit unusual for a tech.
WHY ARE YOU PULLING GOOD TRANSISTORS??
WTF?
er, to test them? lol
