Hello All!
I finally took some time to change out the bias caps on my MS-16 cards and change out what I think were the EQ caps on the rec/play cards as I was having some trouble aligning within spec. Can anyone perhaps put in their thoughts about which caps affect the rec and repro eq adjustments on the attached schematic? I changed out C10 and C21.
Part deux - I have noticed the noise of the machine itself seems high (not quantifying evidence... just my ears). If I have the machine fed into my board - not playing tape - in repro mode - and I have all channels muted (off in the cas eof my board) and I flip one on I can hear pretty significant hiss. Now this is related to the repro level as that hiss goes up and down if I adjust the repro level pot.
Ideally I would have as little noise as possible in the amplifiers on the cards... would an opamp or component change help or do you think it inherent in the design of the cards?
Let me know your thoughts!
Mike
