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 a local collector who reported it was highly functional.  Exterior condition was very good with some peeling of the wood grain vinyl wrap.  The original Sansui shipping box was also included (pretty banged up) with some of the packing materials.

The 7070 was first sold in 1976 and is a little brother of the 9090 with similar look/features including the twin power meters and a midrange tone control.  Like Pioneer, Sansui decided to only use real wood veneer on the TOTL units, which meant very nice receivers like the Pioneer sx939 and Sansui 7070 were shipped with simulated wood grain vinyl wrap (ugh).  Otherwise a very well built receiver that is rather easy to service.

This example was very clean inside and out.  Visual inspection and initial functional testing showed no issues.   Everything worked correctly – including all the lamps which I left as is.  All signs are that this receiver has been very well cared for and has led a comparatively easy life up to now.  

The recap went very smoothly.  I up-capped the main amp supply caps from 10,000uF to 15,000uF.  The new caps are very nice Nichicon GoldTunes that are actually 20mm taller than the originals. 

The FM tuner needed little adjustment and performs exceptionally. 

I can see why this generation of Sansui receivers is so highly valued as I am really impressed with how nice this receiver sounds

The cosmetics on this 7070 are nearly perfect.  The biggest issue was the vinyl wrap which had peeled off in places.  I decided to totally remove the vinyl and upgraded the cabinet with walnut veneer (see photos).
