Kenwood X502-1 Repair

#caraudio #electronicsrepair
This one is a newer one that I have not worked on before, the parts are so small to work with, and the thermal transfer really isnt that great. This is the era that they are starting to get almost too cheap to repair. Can we fix it? Lets find out!

I need you to see mines it's the 502-1 also. It's powers up but maybe the same identical problem. Can you talk a look for me.

I like the outputs made of used wick :)

Neat! Sounds like it would have benefitted from a charge pump on the gate drivers. I've got a Phoenix Gold Ti series amp that I still need to repair. It melted its power cables... I dunno.. 15 years ago... and I haven't yet gotten around to trying to figure out why. Haven't had any amps in a car since then, and if I did, it would likely be Class D now. But it was such a nice amp back in the day that I can't bear to part with it. I had a PPI PC2150 alongside it, which I gave to another enthusiast recently. I go back and forth between being happy it's with someone that will use it as more than a paperweight, and being sad to let go of such a beautiful amp.

i got the x 301 i love mine only thing though is it gets super hot just being turned on

Do you ever see the TL 494 chips going out?

[@THEtechknight]

It's a 50/50 shot. Sometimes I do sometimes I don't, it really depends on how prolonged the voltage was after the failure from the driver transistor's shorting

i submitted for your email address. i've got some presumably cool amps and speakers(b&o) that are in need of repair. i would love for someone to fix them and enjoy them rather than have to send them to the dumpster.

I never received an email, interesting. I need to check the spam filters

I have not seen any emails, So maybe try reaching out to me on Twitter DMs? Techknight2
