re: R-113

My right channel is distorting and cutting out. Where is the RS1 relay located? I downloaded the service manual from this site but it is hard to find this relay in the drawings.

Switches and transistors work OK.

re: R-113

THANK YOU for posting the service manual!

For output transistors, these work just fine and are actually tougher than the originals: http://www.onsemi.com/pub_link/Collateral/NJW0281-D.PDF

Front panel switches on mine are intermittent, and I'm going to try using p/n PTS645TL50 as a replacement: http://www.ck-components.com/14409/pts645_25apr13.pdf/
[ Tune up/down and presets. Switches along the bottom row are different. ]
