I hear so many pros and cons over these. Some like them some do not. I have never used one so hard for me to say. But I think there was a review on EEVBlog if I can find it.
-
I asked over there couple days ago with no replies. I will check more of his video's to see if I can locate one.
Main question is will it work for CB repair. 60 MHz covers it but what about all the other specs?
Thanks Buddy.

Buddy I' ll let you know after Christmas, as my daughter has bought me one,I've only heard good things about them from someone in the club I'm a member of, they do have limitations and can't be compared to the proper S/A that sits here.

That is great news Paul, I can not find anyone that has got one of these and done a review on it. Thanks for letting us know you got one on the way.

sorry for hijacking Buddy, but I need to ask you something, I need to replace some styroflex capacitors, and need to know what type of capacitor would be a good substitute. oh, forgot to mention, it's an old audio amplifier.
thanks

Since it is an audio device then I would use Polystyrene capacitors. Not knowing the values I bet that Just Radio will have them in stock.

they probably have, but I need to get stuff local, and Polystyrene are styroflex capacitors, that`s why I'm trying to find a type that can replace them, I'm going to recap this amplifier totaly.
but thanks anyway

When you say local? Where are you? Finding these local may be a bit of a problem. I cannot think of any one that sales Styroflex caps.

I'm from Brazil Buddy, remember? the same guy from youtube, I need to find another type of capacitor that can replace them.

Greetings Roberto,
What values of styroflex capacitors are you looking for?

Hi Buddy a review on the instrustar, not that good , will never replace the real thing, actually your better off using the FFT on the DSO

Thanks for that information Paul. You are most likely correct. Hard to beat the real thing.
