BOLT BOX aka Eversonic sh550 Buzz sound on tape

[jays]

So the second problem! when I bought the box I knew this was a problem I don't know if anyone has a great hypothesis, I try to deoxit the switch but it seems like that might not be the problem. When put on tape function without having the tape playing a loud hum buzzing sound can be heard! I can play with the switch which will make the buzz signing differently! is this simply a bad switch that needs to be replaced or should I look for something else?

Thank you again guy for the help !!!

Try grounding the deck!

Try grounding the deck!

yeah I already did, a previous post that I mention that I had a loose wire which I didtnt remember where it needed to go was used for to ground the deck.. the big buzzing sound is still present. bouhhhhhhhhh

Other possibilities:

Broken head wires
Record bar (and other switches) need cleaning

 

[hopey]

Sometimes the speaker frame needs to be grounded as well.

Like Norm said could be one of the head wires that have shield over wire either cold joint or break on shield.
