Converting a jap import car radio

"Bob Parker"
It's over 10 years since I got out of doing repairs full time, but now I
remember that Yamaha and others do have different variants of the same
model with the same type number, for different markets.
I withdraw some of my earlier comments. :)

** If you were doing instrument amp repairs - you would have come across
the very popular " Roland JC120 " combo amp ( JC = Jazz-Chorus).

Been in production since 1975s and still available with virtually unchanged
appearance.

See:

http://www.rolandus.com/products/productdetails.aspx?ObjectId=249&ParentId=57


Internally, there are at least 10 distinct versions of the JC120, each with
its own schematic.

Only way to know which schem to order is by the serial number on the
particular amp.

Naturally, guitar players falsely imagine they are all just the same.

Just what Roland wants them to think.

Now that you mention it, I vaguely remember getting caught by some
Yamaha amps with different boards, depending on the serial number. I'd
forgotten all that until now. I must be getting old....

Hi Phil,

Yes I know about band expanders but I don't want to use one.


** Then kindly go to hell and fuck yourself !!

You brainless, ASD fucked, top posting pile of sheep fucking SHIT.





... love, Phil
Now, now Phyllis. Keep your hat on. Just pull those soiled undies a bit
further over your head.

The OP did say from the onset "Yes I know about band expanders but I don't
want to use one."

Perhaps if for once you were paying just the tiniest bit of attention to the
post and not your over inflated toaster ego you'd realise it is you that
should be offering the apology.
Of course we all know hell will freeze over before one of those is
forthcoming from Toaster Boi.

Why bother responding to him? you know by now that he's completely fucking
unhinged. All you do is annoy those of us who have him plonked.

Has been converted, quite easy, the hardest part was removing the head unit
and re-installing it.

All I had to do was remove R61 ( 47k 0805 ) and remove it or move it to R60
and it works straight away.

Thank you to those who were constructive with their help.

Cheers

Hi there,

I have just bought a jap import car and it has a Kenwood DPX-440 cd player
( 2 din )

This model seems to have been sold in the USA as well as Japan.

Does anyone know if these can be converted from 76MHz - 90MHz to 88MHz -
108MHz ( I do not want to use a band expander )

There may be a diode that needs to be moves ( or a wire link )

If anyone can sed any light I would be great ( otherwise I will have to
pull it out an suck it and see )

Option is to change it with a new one but I am a little broke at the
moment.

Cheers

Congratulations on finding out how to do it. :)

Thanks Bob,

It was quite east, there was a truth table and mark M K J and J had a dot in
it, I could not figure out the difference between M & K however, I thought
one may have been 9khz steps for AM and the other 10kHz for the US market
but all three were 9khz.

Cheers

I'd have thought the same as you. As long as it works OK in
Kiwi-land, that's all that matters. :)
