Was replacing the caps I found a strange blue cap marked sayno on it c68 says .1uf 25v any ideas what's the right replacement for that cap ? Thanks
So is 1uf 25v electrolytic good for it’s replacement ?
Thanks I'm not going to drive this radio like a monster going to be stockFor those playing along at home...
@kaos513 - Using a 1uF is "safe" for most - as long as you don't shove too much audio into it while using the radio in a mobile situation - using this in a mobile with a power mike using that values of 1uF can cause some unstable squeal issues from too much audio drive going in.
But again, it's safe for most users. - You also have to remember that the cap prevents the Negative side of the Limiter TR18 - blocks that negative going voltage, from leaking into a filtered and biased audio amp stage - THE CAPACITORS' - if it's polarized, CATHODE (-) End is towards TR18 - else it can fail miserably - there is enough current in the Limiter circuit that it can create an explosive situation if the caps polarity was not installed correctly.
It's a cap sanyoI’m curious to know if the original cap you removed has any polarity marks, possibly a black line or a plus mark. A photo would tell more of the story. The small blue cap you described sounds like it could even be a Dipped Tantalum. Regardless, I would still replace it with a .01 and something close to the original type as possible.
