I think what you are looking for is a 2SK616C. Not convinced the rest of the numbered will help track it down. Search Google for that.

Have you looked at the manual?

F61 usually means the amp has detected a short or a severe microprocessor error.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

im after looking evreywhere for a solution and all i keep finding is:

* ``the audio IC amplifier is damaged and needs to be replace which is cased by dust being inside of the applience``
.
* ``bad regulator for the power supply and needs to be replaced``.

*``RSN is also dammaged and needs to be replaced``.

(all repairs should be carried out by a qualified professionals. any DIY or non-professional work on any electrical items can result in serious health hazzords and even death)

all of which i have looked for from panasonic and even the model of stereo and they dont have the parts for it anymore and don`t seem to have a history of even selling the product! which means getting the parts are nearly next to impossible to get.if you know of any electrical shops that do electronical repairs they would be you`re best bet to try to fix it.they might know of a company who supplied panasonic with the parts needed to make the stereo,or even the next best thing.

please note
some research has also suggested on trying a annolog /fm antenna for radio staions.

no one is really quite sure what the error code f61 stands for but have made some suggestions to what it might mean just like what i have listed above these are only sugesstions that i have found in relation to the f61 error code and where fond on google search engine, youtube and panasonic website.and i am quite sure that even panasonic is not even sure themselves it may sound very funny but if it was the case there would be videos from them on how to fix it and even a downloadable pdf of the circutory board and where the problem lies !!!!!.
