What capacitor would you use?

[Johnny]

If the orginal one said 335K?

This is going in a M90

 

[Johnny]

NORM - WHERE ARE YOU?!?!? I NEED YOUR GENIUS!


P.S. If there are other people so inclined.... PLEASE HELP ME!!


Rating, voltage, etc please!!

 

[Johnny]

I wanna buy new ones, but the radio shack by me doesnt have them - trying to find a comparable replacement.

They are 335k/250v.....

Are these for the big high-pass ones for the speakers? Sounds like 3.3uf capacitors. The originals are not electrolytics and large value film capacitors are pretty hard to find locally and expensive. You can probably substitute non-polar (bipolar) electrolytics and they would be much more cheaper (and smaller) but their tolerance is greater than the film or polypropylene capacitors.

Anyhow, 3.3uf is what you are looking for.

BTW, electrolytics wear out and fail due to the electrolytic solution drying out in them. Non-electrolytics don't have this problem so unless they've failed, they aren't things you would normally replace on a periodic basis.

Hmmm okay, i thought they may need replacing - radio has been sitting for 20 years - no use. I was going to install these along with new speakers.

You NEVER see film or polypropylene capacitors in boomboxes for the high-pass filter on the speakers because the cost is astronomical compared with the standard electrolytic capacitors. JVC went all out on these ones and they are very high quality. I wouldn't change them unless you were trying to change the roll off frequency passed to the tweeters.

Your word is the gospel to me and I will use them!!!

Heres my project - minus knobs I'm cleaning...

the m90 is the only box i have seen use these capacitors and it's what gives the m90 the wicked highs .
