Keith,
I was only able to find Blackgate Standard that will fit in that small metal case (Circuit board
F-2730) Do you have any suggestions? and also where to buy? I am only interested in the audio
path right now......
Thank
Slate

Hi Slate,
Can you post the schematic area of the audio path where you want to change the Caps? Mark the Caps that are the ones that need changing and let the guys with the experience make their suggestions! Those Blackgates are better than what is installed now but there are either better Blackgates and others that will wake this Tuner up!
Also the section in FMTUNERINFO.com makes suggestions on values but not manufacturers and models. I think the experienced guys like the Metalized film/Polypropylene caps in the audio path because they have decent value and a nice impact on sound!
Anybody want to add some experience to the equation please?

Post that schematic and listen to the advice! I am interested in this subject also!

Hi Keith ,
This is the site for the Schematics Diagram.
http://www.fmtunerinfo.com/TU-717schemrt.jpg
On the 2730 board......
The caps that need replacing are the C16 ( 10Uf 16 V ) and the C17 ( 47Uf 16v )
The space is very limited, I managed to find some real nice Black Gates but the size is
too big, for the location , thats why the Standard Black Gates came to mind,they are smaller.
They should fit.
Thanks

Hi Slate,
On the same site that you got the Schematic, they recommend replacing only C18 on that board. Maybe all three need to be replaced or maybe only C18 impacts the sound.
Maybe a large cap with long insulated solid radial leads will let you mount it somewhere, where there is more space. Just cover it with aluminum foil and ground the foil if it picks up RF.
Anybody have a good knowledge of this, who can help? Thanks!

Hi Slate,
Have you had any luck with which Caps to use on the Analog stage? I wish I had more experience and could help.
If nobody here makes any suggestions, try the FM Tuner user group on Yahoo. You have to join, just like here, but their main focus is Tuners, just like yours. I am sure you will get lots of ideas as to where and what upgrades give the highest impact for the effort and dollar!

Hi,
I signed up to Yahoo Tannoy group.
Ever since then I have been inundated with spam.
I had almost none before (<1/month) and now it's averaging 500/month and Yahoo's spam filter cannot cope. It only has room for 500 banned addresses.
I de-registered from Yahoo Tannoy in an attempt to remove my Email address from the spam search engines but to no avail. The damage has been done and they appear to share my address around.

Yikes! I HATE being treated like a piece of e-mail meat!
Makes you think twice about joining some great reference sites!

Hi Keith,
I think I am just going to replace all 3 caps in the the audio section with black gate standard,
they will fit, a bit tight, but they will work out, they can only be better than 30 year old ones that are in the unit presently , the better black gates are just too large. You will have to become exceptionally creative to get them in there.
Thanks

Hi Slate,
Give a good listen, replace, give a good burn in (many hours, hundreds, so leave it on for a week or two), give a good listen (again) and then give a good report.
I am interested to learn thre outcome. Also, there should be some decent improvement over 30 year old electrolytics.

I forgot to make one other recommendation that I read. When you are inside the tuner you will notice the FM antenna leads. One goes to the 75 ohm connector and one goes through a Balun to the 300 ohm connector screws. Remove the balun and disconnect the wires from the connector. On the 75 ohm side, replace the set screw and ground strap with a coax connector for your 75 ohm antenna. This is supposed to add upto 2 db of gain. That might be the difference between hiss and no hiss on some stations! And of course, make the strong ones even stronger!
And always use 75 ohm coax cable for your antenna connections. RG6U is better than RG59.

Keith, I would have to open up the unit first, you kind of lost me on that one, mind you 2 dB
extra? not to shabby , I'll take that any day.

PS. what do you think of the Godar FM 2a ? or do you think the Magnum Dynalab ST-2 is the way to go? strictly indoor

Hi Slate,
The Godar is $69.95 on sale on their site. I have no experience with them. I don't know anybody with one either.
What I do know is that it is strictly indoor as you say and that it is directional. That means as you scan across the FM dial, you need to rotate the antenna accordingly. I didn't hace a 42 inch circle to do that so the ST-2 won for me (no turning required). I also intend to move within 1 year and will mount it high and outside when I get a house.
The Godar in the attic with a rotor might be a nice setup but that gets expensive.
It would be nice if you could test them all side by side and keep one.

Keith,
I just finished installing the Black Gate Capacitors in the audio path of the Sansui.
How long do think the burn in time might be?

Hi Slate,
Congrats! You move fast!
Don't forget to remove that Balun and forget about the 300 ohm FM Connection. Then add a coax connector to the internal 75 ohm wire connection and remove the set screw and ground strap (use a little creativity, there is no exact method) while you have it apart.
I am assuming you don't like what you hear initially or you wouldn't be asking this question!
Now I am no expert, but what I keep reading here is that the Blackgates take quite some time to "burn in" for many of our fellow forum members. Sometimes people get the positive results immediately and then it gets even better with additional hours. However, you should hear some difference immediately, even if it sounds harsh (this happens often and gets somewhat better usually within 10 hours). Don't despair, if it gets somewhat better after a few hours, let it burn in for a week or two continuously (168 hours in a week, so 2 weeks would give over 300 and that seems to be what many say these need). So turn it on, tuned into a strong station and leave it on. No amplification required. Then give a listen and I hope you love what you hear! Then go do the PS caps and rectifiers, etc. They supposedly make a nice difference too.

Hi Keith,
They did sound fantastic out of the box, they are more articulate, you hear everything. I found on the classical station it made the most difference, before it was un-listenable, now it's nice.
I think the ones that were in there were just dried up.......
I bought an extra set so that in 10 years I will replace them again , just in case there is no more to buy. Yes I may do the power supply ones as well.
Thanks

Well then......
With time, they will only get better too!
Way to go!
Don't worry about 10 years from now, hopefully, and I mean hopefully, they will have something even better!
If you really get adventurous, re-do the front end of the Tuner too and that will get you into Nirvana. The TU717 will compete with the best when modified (and it is already VERY nice)!
