I dig watching your video’s but especially these types. Great commentary and educational. You fully recapped my Sansui Eight a year or so ago. Thank you! I love turning it on. I ended up getting my first DAC with wifi/bluetooth/volume control and it goes into the Sansui. Heavenly. I bet these combos will keep you busy for decades…so take some strolls on the boardwalk and enjoy this town. Cheers.
I love watching your videos because you take on some really challenging projects that others would just scrap. That corrosion around the memory battery was fortunately not that bad. I've got far worse on vintage Fluke 8200 series DMM around some niCad batteries that were factory installed in 1973. I still intend to fix that too. ❤️.
I just cleaned off glue from a JVC SR-201integrated it was so caked up from the Factory. It took lots of alcohol and scraping to to remove it. I have the R-1000 changed the caps and new battery it's a good machine.
Dear sir. I have bought 2SD72 and ECG103A NPN transistors for the replacement. I am also having 2SB405 and AC128 PNP transistors. I have tested each transistors by setting the digital multimeter knob to the Diode checking position. While testing the NPN 2SD72 the base to collector and base to emitter forward biased and emitter to base collector to base reverse biased ok. Then I checked the collector to emitter which showed some reading around 220 or above like forward biasing and emitter to collector reverse biased. I thought it was a leaky transistor. The same thing occurred in ECG103A when checking it's collector to emitter leads there was some leakage readings noted. When I tested the PNP transistor, there was no forward biasing inbetween the emitter and collector and vice versa. The PNP transistors were intact because there was no abnormal biasing found. I believe that NPN transistors should be leaky. Above all the circuit amplifies the signal well but the noise or Hum was audible even at zero volume level. But the audio output had no distortion because of the matched pairs. I believe that collector to emitter leakage (presumably) causing the hum. Please suggest me and confirm the condition of the NPN transistors whether it is surely leaky or not. The Complementary symmetry amplifier circuit has been used. Thank you sir I am expecting your kind reply.
Well done as always Jordan, I appreciate this because bought a R1000 new back in the day, had a very short life probable less 5 years to my memory. You mention Hemet Calif. Damn do you live out here in So. Cal. Been looking for someone like yourself, the best Tech on You Tube as far as I am concerned. Have a SX-980 that needs a full blown re-cap.
Great work Sir! For the touchy pots Would some light silicone or nail polish work to hold their position when the customer inevitably bangs the unit around?
I have an R-1000 in my stash that needs TLC. It has to "warm up" to work, with a lot of hate and discontent from the tuner section. One of these days....
Thanks Jordan for keeping this baby alive. One thing I noticed on this unit is that the leds above the input and the power switches didn't light up. There should be a red led light bar above the power button and green leds above the input buttons? Or is that a different Yami?
Only problem I have with my Yamaha is the controls are the cheapest thing they could put in them... count on cleaning the controls and switches every 6 months ... they attract so much dust ... where as I have a Optimus receiver I purchased in the 90's... the cover has never been removed and the controls are still working great ...
Well done, the old beast is behaving itself now :-D I was thinking clear nail varnish for track protection, your misses might have some. STK and Sanken modules are frightning, they die without warning :-(
Jordan watch your mid. sec. your not getting younger and it will take longer and harder to lose it. Trust this big gutted old man he knows what he is talking about. wish I had. sort of like replacing components
Believe me Pete, it's a big concern. I really need to make more time for myself. My workload has gotten so overwhelming these days. I've lost sight of how important regular exercise is.
@@JordanPier Yes, issue is present on any speakers and through headphones. I thought it was speakers at first. I will likely bring it to a local shop as I do not have a background in electronics. I bypassed the pre map so i know its the power amp for sure.
Damn What I Know Now!! When I Find One Of These Just Setting Out For Trash. Instead Of Scraping I’m Eiyher Fixing Or Harvesting For Those Amps. Hard To Get Ics And Fets.

That's a nice looking receiver. Beautiful condition for its age, a credit to the owner.

I really liked this era from Yamaha!

I like how you cover it all Great Job
Awesome receiver. Very nice shape!

Thx jordan, appreciate the deep dives.

When was the last time you cleaned the soldering iron"s tip?
Nice job Jordon!

The lamps all got changed. Was not included in the video.
I have one like this. Top Top Amp Receiver. High Power. Yamaha made High end HiFi A1 Jordan .
Only problem I have with my Yamaha is the controls are the cheapest thing they could put in them... count on cleaning the controls and switches every 6 months ... they attract so much dust ... where as I have a Optimus receiver I purchased in the 90's... the cover has never been removed and the controls are still working great ...
they are nice unit when they are working but they are pain to work on I just got done re- soldering a Sony .
The LED on the power ?
Congrats! Great job!!

I have the same receiver but I can’t find the 2K potentiometer and speaker selector with ribbon. Do you have those parts?
Nope.

I saw a lot of STK3156 for around 25.00 on ebay.
hopefully they are not fake STk's
Some radio repairman 20 years from now is going to curse your name for soldering that replacement battery right back onto that board.
Where can I find the battery please!?
Found mine on eBay
Mine has a buzz in the mids on one channel, any idea how i can diagnose?
Sure it's not your speaker?
Without a scope it's tricky
@@JordanPier Yes, issue is present on any speakers and through headphones. I thought it was speakers at first. I will likely bring it to a local shop as I do not have a background in electronics. I bypassed the pre map so i know its the power amp for sure.
You really need a fiberglass pen for all that corrosion...

7:30 never 😂😂
STK UGH...
