Hi Carroll,

Sorry if a question about a solid state receiver seems a bit off topic
for this "valve" ng...

But there is a wealth of talent, knowledge and experience posting to
this ng.

Due to the age of this receiver, I was/am hoping that someone would
have the information to point me in the right direction.

Most of these "tube gurus" have forgotten more than I will ever know
about tube gear, and some of the same tube guys also serviced early
solid state audio equipment.
I do appreciate any and all input,

Thanks,

Mark
