Grundig MDC65, Sony JE510 and JE780.
You're right - I need to do some testing between decks.
I just thought I'd see if it was something where people would say 'yeah that happens a lot' before I get into it more.
What you say 'if you don't get the adjustment right' do you mean if Grundig/Sony didn't get it right, or do you mean something I might have done wrongt?
