- This Kenwood KA-5700 arrived on my bench with relay protection ON, No Sound...Interesting find.
Left analog Meter reading lower than the right, make sure you watch the whole video...LEFT channel weaker or just the settings?? Find out by watching the whole video.

Great video. Got this KA5700 and a KA3500. I bought them both NEW.....waaay back.....!
My older brother had the same one with matching tuner. I wore out the Abbey Road album on that thing...when he wasn't home! I remember the volume knob precise clicks....so satisfying.
He blasted FreeBird daily on the damn thing. I was 14 years old. Great memories.....best era ever!!!
I hear yea!
I was about that age when my older brothers playing their music but watch out when they were not around.
Great memories, good music...Love it! Something about it that never will go away!
thanks for sharing, man
That laser pointer trick is a neat idea. The number of times I've desoldered the wrong thing.
Awesome! I had one of these when I was 19, I bought it new. And I recently bought 2 of them, one working and one not. I will get into them one of these days.
Another beautiful vintage amp saved, well done!
I have a KA-5700 & the tuner KT-5500, they work fine and now i can also calibrate the VU meters thanks 😃
That turn table is a great idea! I wish i thought of that.
Thanks. Great video.
Nice work Joe!!! You have inspired me to get back to the bench in retirement!
Hi.....well I'm happy you'll have a great hobby for when you retire
Nice job Joe ! good looking little amp too. If I had more rooms I'd have more amps LoL ! I've been working on a Nikko Alpha 220, just finished it up.. took a lot of re-checks to catch everything but SO worth it !
Good job 👍
Thank You
excellent!
You're a legend Mann! Everything is perfectly done epic content.
Thank you so much for the nice compliment...glad you like my video.
Enjoy!!
Всем Аудиофилам П.Р.И.В.Е.Т. ! У меня КЕНВУД КА 7500 с 2000 года. Работает на 25АС-2 с фильтрами от 35АС-1 звук космос! Слушаю на нём в основном CD.
The Capacitor Wizard easily checks caps in circuit without necessarily needing to remove the part. I suppose you know that. That's why I bought mine. My other checkers require you to push a button for test. Not handy at all for in circuit testing.
Hey Mark....Yes I just recently bought the Capacitor Wizard...well maybe a year ago and it works wonders...with the WIZARD If the cap test bad in circuit....it just BAD. take it out and replace it. I always check them after and at 100% accurency.
wizard is truly a MUST! I enjoy it very much.
great video. just one question the about thesmall electronic tester with the zip connector ? where can i get one?
Love this video. I discovered the laser trick myself a bit ago. Question about replacing big power supply caps: Mine have two leads and one stabilizer but new caps just have two. Would you glue those? Would you not replace them if they tested fine? I assume they're not going to affect sound if OK but could be bad if they went.
Hey David....i did change the big Caps on 2 amp I think...when I ordered them.i made sure I had the original ones...one i recall I was able to get the 3pin capacitor so they are available at digikey.... and i didn't use glue...that is to each its own...yes after 30 years so so the glue became a issue.(corrosion) etc. But if you feel like you want glue there.... go for it...just easy on the glue and I would make sure other components don't get affected by the glue...
sir gud am, i have def. kenwood integ. amp, can i perform dc biasing without connecting output transistor, thnk you so much God bless...
👍👍😎✌️🤟
nice I just picked up a KA-305 not as nice maybe but I like the looks . how did you know the 2 caps are the only 2 bad ones?
I tested them all and only found 2 capacitors with HIGH ESR and needed to be changed...
I have one Kenwoood RXD SL3MD, while I'm using it in auxiliary mode, suddenly it cuts off the sound and starts rumbling, whining,,, and no other type of sound comes out, I live in Brazil and this model is not common here
Hey Joe, Would you have any suggestions for same amp blowing the F2 and F1 5A fuses when turned on?
Did you check your output transistors..check them and see if they are not short
Nice video, i have this Kenwood, but the fuses keep blowing, without even giving the relay time to click on, I don't know why.
well you need to get yourself or make it yourself a DimBulb tested
I have exactly the same model. The transformer is not working 😞 I can’t find one. Apparently discontinued
Did you get it check , you think it's the transformer?
I have one that doesn’t turn on at all. Lights out.
Sir i am india
Thank you for watching ☺️
What can I do to fix it.
Hey Micheal...
It's pretty hard to diagnose without being here on my bench..it could be ALOT of things.
Check the fuse first see if open with a multimeter...if not the fuse check for obvious issues..hots spots on the pcb board, it's usually pretty easy to spot problems ...
@@VintageAudioFever I changed the fuses in one of the amplifiers and now it works but the display light doesn’t come one. The other one when I changed the fuses and turn it on it blows the fuses instantly.
@@VintageAudioFever
Thanks for your help and reply.
@@michaelreyes6761 usually when the fuse blows, there is a major issue with the amp ...
Maybe the output transistor....
@@VintageAudioFever I can see a spark when I put new fuses and turning it on by the outlets on the back of the amplifier
Might I suggest you drop the over loud music? Adds nothing to the video.
well I kind of like music when Im not talking ..I could turn it down tho for sure....I do appreciate your commment tho.
something to think about for sure
since you have alot more subscribers than I...maybe you have a point haha
I will subscribe to you channel also
@@VintageAudioFever Hi Joe, I guess it is a matter of personal taste really. The subject matter is kind of serious. Most of my subscribers tend to not be teenagers or very young, they simply have no interest in audio or electronics. Background music is a YOUNG thing, they cannot concentrate for more than a few minutes without it.
It takes a long time to build up subscribers, particularly in our subjects. Simply not enough people interested. You will be very lucky to ever make any money out of it. I don't even cover my costs! Just a bit of fun and my hobby. Good luck with your channel.
@@MichaelBeeny excellent point, I do enjoy music on mine but I will be careful not to LOUD..hha
thanks again.
@@MichaelBeeny I'm kind of hoping I will eventually make something out of it...I love repairing vintage amplifier, been doing this for over 20 years but I'm new at making videos and find that the hardest...editing takes me forever. hoping I will get better at it. ha-ha!
where are you from if you don't mind me asking?
