Beyond the list of standard restoration steps detailed on the main page, here are some added notes for this unit :

I acquired this receiver from ebay with assurances of high functionality.  Exterior condition was very good.

The CR1000 was Yamaha’s top-of-the-line receiver in 1974.  It uses the same class A/B amplifier modules as the highly regarded Yamaha CA1000 (rated at 70 watts per channel driving 8 ohms).  Styling is distinctive as sliders and switches are used to leave only 2 knobs (tuning and volume).  These are rather rare compared to its successor (CR1020).  They have a reputation as being hard to work on as the base serves as the chassis (so no access to boards from the bottom).  Yamaha designers did provide ways to separate/remove major modules, so really not that difficult to recap if you read the service manual 🙂

Initial inspection showed some minor cabinet marks on the top and vent grill.   (see last 2 exterior photos for more on these blemishes)

Power up testing went smoothly with high functionality with a few issues

     The meter and pointer lamps were dead (replaced)

     Some switches caused channel drop outs (resolved by cleaning contacts)

     Dial string was stretched/loose (lubed all the pulleys and installed new string)

     One speaker terminal was damaged (upgraded all speaker terminals with modern 5-way types)

Recap went smoothly.  Per AudioKarma best practice, upgraded over 50 “replace on sight” signal transistors with correct modern equivalents. 

The tuner is “FM-only” and sounds pretty good.  

Functional testing complete/passed.  After cleaning and reassembly, I think it came out quite nice.
