Question about Audio Players & Recorders
When I power up the unit the left VU meter pegs out and begins making a clicking noise due to the fact that it is repeatedly pegging out to the left. How can I get rid of this? Sometimes when I flip the monitor switch back and forward I can make it go away and then it starts to rebuild energy and pegging out again (this doesn't work all the time). Also I want to stabilize the machine, the axis turn really corky and it keeps hitting the tape and adds a lot of wow 'n flutter. Any tips on that?

These 4000 decks are notorious for bad transistors and you are describing a capacitor that has gone leaky. So it can be either of those conditions. There is no easy fix a Technician will have to work on it to get rid of the problem otherwise it will just get worse. All these older machines had capacitors that are at the end of their lives. Too many years on them. The slide switches in them also need cleaning with Caig Deoxit. Other contact cleaners are not as effective.

The heads are out of alignment. This is a simple adjustment when using an alignment tape. Realize that any tapes that you record at this time WILL NOT play correctly once the unit is re-aligned. This should be a relatively inexpensive labor only repair.

Follow the left channel lead to where it joins with the PCB. Use a pointed tool and prod connections if you get a buzz then that stage in the amp is working. I suspect you will find it leads to a IC that might cause the fault. If you find it buzzers on the right but not left, then it's gone. PS don't short pins. If you can get hold of a signal injector it will make things easy.
Be careful and good luck.
