Hi everyone, today I found a cassette box CROWN. he had no radio.

there is no antenna
This box can not be boombox?

Who has information on this box please give me more, thanks for visiting

So it only has 1 speaker but they make it look like it has 3......nice.

Very unusual

crown box made in Japan 

If it's mono & has no radio, what do the three knobs do?

Volume

Tone

?

this model

this is the recorder cassette box

"Public Address Speaker System", eh? That might explain it. Perhaps it's a mic mix control...

I've got it, I can not believe my eyes.
That's CROWN CCR.102
Can not find this model on Google?
AC 110V and 220V
12V DC
Three button three buttons that are Bass, Treble and Volume. Have AXUS
and no radio and antenna

I bought it ith price 4.5 usd
