- First and Foremost, I want to give thanks to ALL of the AKer's out there that helped me along the way to bringing this old girl back from the grave. This receiver was handed down to me from a dear friend that lost his life. The value of it was far beyond any money value. Trouble shooting the fact that it had a blown thermal fuse in the transformer was the first step. Then replacing the P800 power board I snapped in half lol. (Thank god for eBay). After seeing her power up again I made a dedication to attempt a full restoration. It took me a little over two months to complete. Lot's of learning and soldering advancement along the way lol.. I want to give Catrafter a special shout out for walking me though the MPX FM board. Sure enough. It was the IC chip that was causing the no "stereo" light. Thank You. I replaced all the electrolytic capacitors, shed transistors, IC chip, and tantalum caps throughout every board. Mostly with Elna Silmic 2 and Nichicon KA in the audio paths. Panasonic FC and Nichicon UPM for the Power supply (built like a tank). New speaker relay. I upped the VDC on all caps by 25/50%. I used some polypropylene Wima and Panny films on the preamp (also a few Solen), Phono, and mpx board. I had issues finding some values here and there. The main caps are Nichicon Fine Gold 63V 10,000uf. I used Nichicon Muse caps in a few bi polar spots and a few Fine Golds here in there. Kind of a mixed bag really. Paid more in freight to mouser than parts I think lol. It was a learning experience lol. I ordered a black faceplate from Germany. The walnut case stateside. I must say. Nice touch. Upgraded all the lighting to led. New vellum paper. Cleaned everything throughout. Used Deoxit and Fader lube on all the pots and switches. Set all the Bias levels to factory specs. Didn't have the tuner professionally aligned after the re-cap on the FM board but she's pulling stations great. Thank goodness. So yeah, I have a new found passion in learning more about this trade. Its very rewarding. Thank you. Everybody. Hope you enjoy the pics.
