I've recapped a few boxes. The capacitors are still available at electrical parts suppliers. Avoid the cheapo ones though. You'll need a good solder sucker. Just do one cap at a time, observing polarity. The 5350 is a modern box and is easy to work on - basically plug and play.

I usually replace every electrolytic cap I find but don't touch the tuner board caps.
Take your time and you'll probably enjoy the experience!

James....

Please don't forget to take pictures of the caps showing polarity signs from various angles. These pics have helped me a lot!

The PC board got several "built in resistors" which are hard to identify.

Panny 5350 board is easy to crack based on how it is mounted.

This motor boating sound could be a crack on the board near the ground or bad cap/s. Look for any swollen top heads on caps. Some may not swell but will be bad.

It is very easy to take the board out and also the deck section. Undoubtedly it is one of the best boombox internal designs!

See those low value resistors on the board.....R141, 241, R470 and so on....

As I said this could be as simple as bad ground. Is this a 100v unit Joe? If so I would be cautious plugging it in to 120v US power source.

There must be a 115-120V voltage selection. That is how mine is. I've not seen any King Pannies at 100V. Nope

Yes its the 115-120v box and the switch is in the right spot.

Thanks for the inside pictures. Gives me an idea what to expect.

Hopefully someone did not alter it inside. good luck with it!

Here are a few more Joe...

Oh I'm wondering if it's the orange caps that are bad. There was a post on S2G a long time ago about orange cap disease

Sazeus, it must have been one of your threads that I read about the 5350 needing to be re-capped, but I can't find that post for the life of me.


Did you re-cap yourself or send it off for repair?

I can probably handle it, just need to figure out how to make time ot do it. The worst part might be trying to find all of the right capacitors, not looking forward to that.....

Oh sorry, didn't see this post until now. I enlisted the help of another member. Wills15 he's not so active now but has a steady soldering hand and taught me a lot about fixing these puppy's.

We just did the blues as I recall, he reckoned they're the electrolytic ones that dry up over time, the orange ones are polyester caps that supposedly last forever (I'm told). We just did the amp board, not worrying about tuner or deck section. I ordered Panasonic caps that cost a bit more but you know are good.

Will got it done in maybe 3 hours I think.

Not that it's a great deal of help, but here's the thread about my one.

That is correct!

Who in the wild World come up with problems of orange caps?

Little knowledge is dangerous!
It confuses the members here.



I was also getting confused when Bill mentioned that.

Those orange ones I always left them alone.

The ones bbl are referring to are orange electrolytic ones which went bad in many electronic circuits from that era because of a manufacturing fault (iirc they were korean). Some wrong mix of compound was used or some such which caused them to blow over a shorter than expected life span.
The ceramic caps can go too but are very unlikely to.

Hi Docs, I got it! They are referring to the orange cap disease like the "Nakamichi Orange Cap Disease"

I will surely tackle the cap replacement on my own and kind of track it in my repair thread. I appreciate all the tips and info guys, it gives me a little courage to get in there and soon. We have a couple more weeks of camping season, then I will get the operating table setup in the garage .

Good luck Joe. I would put a mark with marker on all the ones your changing so when you pull n replace you don't get mixed up

I got that tip from another member in the past. Looking forward to it
