Hi AKers,
It's been a long time coming but I'm stoked to finally have this project completed. Before I start, I just wanted to say Thank all the AK members who have posted their recap and restoration threads, in specific Merrylander!
I wouldn't of able to complete this without the advice, guidance and wealth of knowledge here. God bless the internet and AK so Thank you!. I also believe that sharing information like this is a form of me giving back to the community and more importantly to share the passion from one enthusiast to others
Anyways so lets begin, my beloved Yamaha CR-2020 Receiver is my first ever piece of Vintage equipment (and subsequently the piece that started all this Vintage mess!).
For the past year she had been the main listener in the living room until she started acting and playing up. Her symptoms included, random intermittent cut outs on the output while unit still powered on. She was also running 'burning' hot, I suspected that this was due to previous tinkerers not properly adjusting her bias, and/or the trim pots are so old they have started to drift. After some light tapping on the side and her output comes back on only to keep turning off again, not good. After the 3rd drop out, I turned her off completely and decided it was time for a full look under her skirt.
When I purchased her, the previous owner said he had replaced a few caps in the Power Supply unit, upon inspection I saw about 4 Nichicon PW caps. Why he did not recap the entire unit is beyond me??
I will try provide commentary along with the pictures of her journey.
Starting from when she was first shipped to me, she had suffered some severe damage on the right hand side of her case due to the idiots at the courier company packing her with the 3 metal prongs from the power plug against her side. Ouch!.
My last years setup with Mr Yammy
24/03/2014 - Ready for her restoration
First output board recapped - Panasonic and EXR caps were the choice
Original Toshiba Output transistors
Output board tag strips were so brittle they broke when I started the dismantling. Will need to repair these later.
