Project: Yamaha CA-2010

[Super Noob]

Here is my latest expedition with vintage stereo. Must admit that I am sucker for large WPC vintage gear by the usual suspects: Pioneer, Sansui, Marantz, Kenwood, Fisher... and many others. The recent rebuild of the CR-620 & CR-820 have enhanced my focus on Yamaha.

The CA-2010 seems to have a good following and many like. Trolling the typical used local sites, found this unit about 2 hours away. So here goes my rebuild project.

The rebuild sheet should help anyone that might rebuild in future.

Little dirty.... but workable.

Someone has been on the board before.... one of the fuses was retro with some crazy large package fuse. Two capacitors where change and four small transistors were changed (all replaced).

Looks great and I bet it sounds fantastic.

Thanks for the extensive documentation. Let us know how it sounds! I've been looking for one of these for a long time... if I ever find one, it will be nice having this as a reference.

This thread is restoration porn . Great pics too.

Hello

Can you explain us why you replaced all these transistors ?

Restore or repair a unit is not replacing everything without reason (why if they are good ? )

 

[Super Noob]

This is a good question = your mileage may vary (YMMV)

There was plenty of black creep on most of the semis & large diodes.. and I like to replace all smalls. Have done plenty of re-caps only as well as full rebuilds.

My preference for MY EQUIPMENT is full rebuild. If you gave Yamaha in 1978 the choice of what I put in verses what I replaced, I doubt it would be much of a discussion. It is preference = your machine / your call. Doubt many would want to pay the cost for this type of rebuild = it is costly - not the parts but in terms of time spent.

It sounds very good - "natural" - as they like to say. It is my office area - running it through the paces = and it is very transparent and crisp.

Awesome documentation and restoration well done!!

Wow, nice restoration! Thanks for sharing all the details. Hope this helps someone with a CA-2010 sitting on the shelf awaiting restoration.
