Wow, thanks for the helps, pals…

And tvi, those links are great! I like the DIY page at www.fmtuner.com.

And as I have thought (nania was right), whichever tuner I choose, I will be able to upgrade the performance dramatically by parts upgrade (especially the filter). So, the physical look of the tuner will be my first consideration.

With many other specs, I don't think that they will be available as a label on the tuner body. And of course, the seller won't be able to answer if I ask. So, knowing the top FM tuners will be helpful (but I don't have a membership to the yahoo site nania gave me), unfortunately I don't think that I can find them easily in my country.

I have been looking for NAD tuner without success. I hope that this tuner uses OPA OP-Amp, so that I can replace it with a better one.

You may be a Macintosh fanatic. But you should not blame Windows for every problem you have!

I wrote the text on MS Words before pasting to the text box. MS Words recognizes 3 types of quotes (straight, curly, and the inclined one). As far as I can remember, the double quotes causing the problem is the one "inclined". I think it is ASCII #147/148 in Latin I character entities.

Next time, Dave...

I promise I will check the paste result before hitting the submit button

Curly quotes... i have been using them on the Mac since 1985. Usually the default is to off but Microsoft alway seems to turn everything on (one of the reasons for ALOT of the world's virus attacks). Any ASCII above 127 used on the internet is going to break on someone's computer somewhere (i am quite cautios not to use any of these platform specific characters), it would be nice if there was a standard character set, it could make alot of these posts richer.

dave

ie (if, on some platform where these screw up -- it would be interesting to see a snapshot)

curly quotes ÔÕ, ÒÓ
degress ¡
bullets ¥
omega <font face="symbol">W</font>
n, m dash Ð Ñ
mu µ

What is capacitance diode?? Whatever it is, I don’t think that a good variable condensator (I mean the one from metal housing) can be outperformed by… diodes??
Let me ask you: How are tuners tuned since 20 years back? Yes, capacitance diodes!

This is a diode which has higher capacitance than a normal one (but you can use a normal one also). You bias the diode backwards (plus on cathode), then you will get a capacitance which vary with the voltage. I have a capacitance diode in my vinyl amp (Denon PRA-1200). The diode creates a stepless capacitor from 200-500 pF.

The advantage of a real air-spaced variable capacitor is a more pure local oscillator signal => Lower noise
