Hello James,
I have no first hand knowledge of image problems with
the 10b, I have just encountered reports of problems with
the close spaced signals. The 10b's reported on, of course,
may have needed work or alignment. If I had a properly
restored one, I could answer my own question pretty
quickly.
Anybody out there want to sell me a working Marantz 10b
for $1000? :-)
