Hi all, I have an RT-707 that I dug out of storage last year after about 18 years or so I guess. I had some squealing on the right channel during recording and fixed that with a couple of transistors on the power and oscillating board. It records and plays back wonderfully, with no issues, but one concern that I noticed recently as I'm recording my excellent vinyl to tape to save wear and tear on those.
When I record, and have "tape" selected, I have normal and equal deflection of the left and right meters. However, if I go to "source" I noticed the left channel meter has a somewhat higher deflection than the right channel.
To confirm what I was seeing I downloaded some test tones (700 and 1K), burned to CD and played back. Sure enough, in the source position the left needle is about 1.5db higher than the right, BUT in the tape position they are spot on equal. I thought possibly it was my Kenwood preamp but I ruled that out with another spare I have. So, I'm unsure if that difference between the channels in "source" is an RT problem or not. I did recap the line in amp and also changed the transistors according to Trevor's thread thinking that was it, but no joy.
My record and play are perfect and the sound is equal between the channels, it is just the source difference which is driving this question. It doesn't affect anything I can see or hear, I think?
Any ideas you may have or just not to worry about it.
