Quick Repair of a 1968 Fisher 500t stereo receiver. Right channel out. FIXED

[@mrvwbob156]

Excellent video My Kenwood is sounding great after your repair Wanted to say thanks

[@JordanPier]

Glad to hear it. Really is a nice example of that series.

[@ethelryan257]

Ah, back when The Fisher was still The Fisher and not a zombie brand of trash. Gosh, I miss those days.

[@YUHJKT]

It is always satisfying to watch a pro work through a problem with trouble shooting and over-coming a mistake that if I did it I would be overwhelmed. Very good video.

[@pubsub9832]

I'm always impressed with your videos which show how quickly you are able to diagnose and repair something that likely drove someone mad for months before they brought it to you.

[@damusicianstrikesback5337]

Came out great! I had to do the same exact procedure with a Philco Ford table solid state stereo table radio. Left channel was dead. Traced to 2 caps in the left channel path on the output board. Replaced both those caps. Both channels working now. Luckily for me they were easy to get to.

[@davemc162]

Well done and well explained. Thank you!

[@AudiophileStooge]

very helpful, thanks!

[@nickbracamonte]

I love that your bench looks like mine lol random stuff, tubes, deoxit, hakko iron, 20mhz analog scope etc all strewn about! Another great vid!

[@6StringPassion.]

You're great at demonstrating a practical approach to troubleshooting. Thanks.

[@afzaalkhan.m]

Excellent diagnostic tutorial and repair .thank you Mak Pakistan

[@justsumguy2u]

Nice troubleshooting and repair. I was surprised it wasn't a driver or output transistor(s)

[@batterymakermarkii2654]

I had something along those lines in ‘88, I think it was a 440? Pretty good rig, but nothing compared to the 800c I purchased later

[@scrappy7571]

WOW, that was an easy fix! My dad has a 440T, he bought when I was in 1st grade about 1966. Still plays ok, one of these days I'm going to give it a look over. I believe it has output transformers instead of caps. Visually it look similar to this one.

[@williamsquires3070]

That piece of crud on the scope bezel would drive me crazy. 🤬🤯

[@JordanPier]

It's annoying. It's baked on too. Regular cleaning with windex does nothing

[@pathfinderdiscovery9395]

Man I enjoyed your video , I’m back to collecting retro receivers tape decks EQ ‘s , and amps , small collection right now but some of them need cleaning , at connections RCA jacks , so it’s good to know about electronic cleaning solutions or sprays , I’m subscribing to catch more info , thanks in advance for showing me , well is some technical fixes so restore older well built equipment

[@rogertyler3237]

I Had A Fisher Reciever The Left Channel Didnt Work But The Right Channel Did But All I Had To Do Is Replace The Left Speaker Fuse.

[@KentTeffeteller]

Amazing output capacitor replacement and Avery is singing again, with a little complexity in mounting that new terminal strip, Jordan, nice work! Glad to see this 1968 classic bit of USA made audio history making music again!

[@tectalabyss]

Watched this when you first posted. Can't remember if I commented. So, Great job fixing the receiver. All my best.

[@bertroost1675]

Looks good. Do you think these are comparable to the earlier tube receivers like the 400, or not even close?

[@JordanPier]

Apples and oranges. They are nice sounding units, but sound nothing like a tube unit

[@bertroost1675]

@@JordanPier I figured but I do want to get one someday.

[@zari63]

Hi jordan great video !!! tel me please in your site u say that u repair only vintage stuff, why ????

[@vwr32jeep]

I only lose the right channel when it’s in stereo. In mono mode I get sound from both speakers. :/

[@JordanPier]

Check input switching, particularly the tape monitor

[@vwr32jeep]

@@JordanPier thx!

[@chevguy8587]

Why are the old caps so much bigger then new ones?

[@justsumguy2u]

Advances in technology

[@python27au]

9:02 how do you do that test if you don’t have a scope?

[@JordanPier]

Clip it in and see if your missing channel comes back

[@Reflectiveness]

I know next to nothing about electronics, but cleaning the pots first makes sense.

[@johnnoland4249]

The unit looks its been in a damp/ocean beach environment. but as your in San Diego, I guess thats why.

[@harlest71]

Great job JP !! I wish I lived close to your shop, I've got about five receivers I'm not smart enough to fix.

[@fr6885]

The Tape Inputs and Outputs are also great places to test Pre-amp and Power Amp functionality.

[@kawoeliskirmanto217]

At that time, pcbs were still a luxury item, component terminals were still a mainstay….

[@dougtaylor7724]

I have one of these. They are great. Wish I could find a shop to recap it and go through it. She blew a fuse 10 years ago and I never turned it on again.

[@majordisappointment8692]

Cool repair did anybody catch that screw under the board behind the tuner board or am i just seeing things.

[@andershammer9307]

Love the way those receivers look. I have a 500C. And a 400T.

[@Poppinwheeeeellllllieeeeez]

Classy looking receiver. I has a sherwood of that era that looked and sounded great.

[@t1d100]

I know that you hit a snag with the bolts, but I solute you for doing a proper installation of the caps with a lug strip.

[@peterjmcgee4680]

I think that would look much better with blue LEDs

[@saarike]

Simply 👍👍👍👍and nice radio/amplifier.

[@AiMR]

A Fisher amp with all the brass knob inserts intact 😮

[@levimevis5192]

Did they make these old Fisher Receivers in an AM/FM Stereo version or were they just FM Stereo only?

[@JordanPier]

I think the 400t and 440t are the only ones with both am and fm

[@petermartin7065]

Great job, Jordan.

[@josephsirois2353]

Easy peasy lemon squeezy

[@tarstarkusz]

Isn't it "normal and customary" for you to do a quick power output check?

[@JordanPier]

Always. Often reveals problems

[@Luke-12V]

Verry nice ,thanx

[@waltschannel7465]

Hmm, good tip about de oxit and pots. Natrol it is...

[@m.k.8158]

actually, no problem with using DeoxIT for pots-just use the correct type:F-series NOT D-series. I'm guessing that he had problems with D-series-this is for METAL TO METAL contacts. So it's ok for contacts, switches, etc-but the only type of pots that it is ok for is WIRE-WOUND ones. Normal pots use either conductive carbon or conductive plastic as the resistive element, and these should not be treated with D-series DeoxIT. F-series DeoxIT (used to be called FaderLube)is safe for pots.

[@magnoliatom1300]

How could I get you to work on one of my receivers?

[@JordanPier]

Repairaudio dot com

[@davidnorton573]

Just a note that it looks like you replaced a 65V cap with a 50, not sure I'd leave it that way.

[@JordanPier]

Voltage on the cap is 38 volts

[@davidnorton573]

@@JordanPier Sounds about right, half the power supply, however your measurement is static. Consider that the capacitor does have a dynamic voltage applied. A high frequency spike into the inductive load of the speaker will drive the voltage across the capacitor up. The original designer considered the 65V part appropriate, I wouldn't second guess them. Anyway, it is your lookout.

[@zx8401ztv]

I'm surprised it doesn't have more dodgy caps, that's a reliable old beast :-D. The only fisher i knew was a cheap and nasty plastic thing. That must have been the take over effect. it looked like a toy, not a serious amplifier at all.

[@justsumguy2u]

Right, those were built by Sanyo in Japan, after the takeover....the one Jordan has there is made in USA

[@kevkabluebird1032]

Hello there and greetings from germany! If you do the FM / IF Alignment with a sweep generator... is it mandatory to have a trigger function for the oscilloscope? My sweep generator sweeps back and forth just fine with 10,7 centered but i cant trigger nor do marks with it. So i'm not sure if its worth messing around with it or not. Thanks in advance!

[@JordanPier]

The scope I have triggers based on settings of vertical or horizontal sweep amplitude, or by an external trigger.ive always used the internal settings

[@rogertyler3237]

Look For A Speaker Fuse.

[@JordanPier]

Yep, normally that's true. However this unit has only the main power fuse

[@jdmccorful]

Nice work! Enjoyed watching, thanks.
