[Vintage-Audio] Re Need Part For Yamaha CR-1020

[Duane Fischer, W8DBF]

Hello All,

I acquired a Yamaha Natural Sound CR-1020 receiver. Today I discovered when 
I switched it to stereo in the FM mode that there was no left channel output 
to the speaker. I tried the speaker select switch on both the "A" and the 
"B" speaker connections, nothing on the left channel. I have checked all 
switches and they appear to be properly set.

On the chance that the problem was in the internal FM tuner, I fed a stereo 
cassette deck in the auxilary input jacks. Still no left channel.

I tried a pair of stereo headphones, no left channel.

The receiver does have the 'FM Dolby' switch, it is in the 'off' position.

Any suggestions as to something I may have missed setting correctly?

If it is the audio output transistors, can anyone tell me what the make and 
model are? Where can they be purchased and how much? I hate to see this 
amplifier relegated to the trash, even though I have yet to use it since 
acquiring it, I love the specifications, features and front panel layout.

Thank you.
