It is noise.
ReplyDeleteThe output on all of them is a bit noisy. One of the reasons, there's an extra headphone strength amplifier just before the 1/4 socket that doesn't run to the 1/8 output.
Steps to avoid this; Replace with a modern chip in place of the LM386.
Also, there is no shielding between the high frequency noise circuit and the audio outputs, this is of concern, too. Try some shielding foil.
Mine didn't used to make nearly this much noise - it was quite a bit quieter than the noise floor of the tascam ministudio I used to use it with. Somthing pretty seriously wrong is going on - maybe a bad capacitor or something. For what this is worth, you'd probably be better off finding another one that works right than bothering to fix this one - there's millions of these out there.
