Yamaha CR-2020 Help!

OK. Ideally out of circuit. TR703,707,712 and 713.
Consider replacing these electrolytics- C713,714,717 through 721.
Also check the forward and reverse resistance of D715 zener diode.
 
Too bad we never met. I was with the 3207 (?) Vehicle Maintenance Squadron. that was so long ago. The squadron number might not be right; my memory is fading....

Man I loved to watch those F-15s tear up the sky!

The reason I joined the AF was just to be near those awesome planes!
 
Sorry I've been busy lately. I have checked transistors 703 and 707 and they checked out ok. But no matter how careful I am everytime I take out a transistor traces lift.:sigh:
 
Alright so I checked the last two transistors and it seems t713 is shorted.
 
and i'm thinking if really need to recap the phono stage as space is quite tight and removing the whole board takes lots of work..
 
i fully stripped down the front panel to get better access on the boards and pots for good deoxit..hope i can bring it back altogether20180128_160831.jpg
