Redfire JVC RC-M90

[SLO]

I dig the red Looks good in the pics Joe, good luck on getting that sound issue fixed, man that bums me out

Yeah it is a bummer. If I had to guess, I think it has to do with the switches. There is something nasty going on with the Function, NR, and REC switches. The sound was fine when I got it, and after the mods, then one day I turn it on and the sound is funky. I will test the line-out when I get a chance, this might shed some light on it.....

Man, that's a beautiful looking M90. Congrats on a job well done!

Sorry to hear about the sound,

Two things to try out... 1) try toggling the phono/line switch on the back a couple of times and 2) put in a throw-away tape and put the deck in record mode and hit stop.

Now you got me thinking about painting up my M90....!

also check the band selector switches , these get dirty over time , i always have trouble with mine but i'm too lazy to fix it.

 

[blu_fuz]

Thanks for the kind words and motivation.

Next step is to swap in another set of M90 speakers and see what happens......

Try cleaning the line/phono switch on the rear.

Try cleaning the line/phono switch on the rear.

surprisingly --cleaning just that little part has ALWAYS worked to bring m90s back to full life-
plus -as floyd said --the FM buttons often need cleaning to get clean stereo

Try cleaning the line/phono switch on the rear.

That was the first one I did when I had the boards out. I will investigate that again.

All the switches were de-oxed from the inside of the box when the boards were out including the radio bands.

That is frequently a very difficult one to clean well. On Holly's M90, I had to disassemble the switch to mechanical scrub and grease before reassembling.

Those are simple switches to open and clean up at least.

All the switches are working. The line-in/phono switch good too. The floppy speaker issue is through any audio ie; radio, line-in, cassette.

If I had some time to get these speakers swapped, it would eliminate that variable......

 

[blu_fuz]

Swapped the speakers, same result....... Boo

 

[blu_fuz]

The blue-ish M90 speakers look better than gloss black. I also took the red plastic off the VU meters. I just wasn't feeling it.

Shits about to get serious......
