How to clean Panasonic SV-3800 heads and tape path

First take the top of the unit off by taking the 4 side screws and 6 back screws off with a philips #2 then locate the transport

The transport in in the rectangle and the drum with the audio heads is circled in the back.

It is shiny silver and has 2 heads on opposite sides from each other

each heads is unbelievably delicate, so never touch them with your fingers or attempt to adjust the set screws.

Now Eject the transport all the way out

Now unplug the unit from the wall

Then push the drawer bad in till about the point shown

This will give you little more wiggle room to reach the head with your fingers and card stock mixed with alcohol

Now take some nice card stock or a business card.

Tear off a park of it and dip it in some alcohol or head cleaner.

Insert alcohol soaked card stock thru the back area of the heads as shown.

Reach around the back and press ever so slightly with your finger(in the direction show by the arrow). Push just enough pressure on the assembly that it will remove the dirty from the heads. This pressure is very little, only enough to press the card stock against the heads.

Press too hard and you will damage the heads or shread card stock and make the heads even dirtier
