Hi comrades, I found on flea a little JVC 4907LS mono box in mint conditions.
Everything works but wen I press the play button from the speaker come only squeak sound, anyone know what is wrong?

Problems with the tonehead?
Have you cleaned it?
Is the tapespeed right?

Mice?

Just kidding-A good clean-up and lube the parts that need some lubricant and that should hopefully work.
Good-luck-Ghettoboom777.

Thanks guys

Love the National in your Avatar. What model is it ?

It´s an National Panasonic RF5310 if i right remember?
Very nice mono!
I have seen many National´s, but never this one in nature.

Also try puting in a blank tape and pushing down on the play/record button a few times, possibly with a little lubricant, and then try playing a tape.
This has worked for me before.

Thanks AZA, that is work but not for the long time.

But your suggestion is help me because i see the problem ,
The inside slider for recording (on the board)was very dirty.
I was sprayng the slider with contact lubricant (for car contact), and now work GREAT.

Thanks guys for suggestions, i solved the problem.
