Concept 16.5

[tarior]

A soft start circuit can be added to any unit. Some time ago EchoWars posted a circut for it. Also, CDfixer made up some pc boards with all the components on it. It is a very neat installation.

Also, many power switches are a generic part. The switches that Sansui used in many models are still available. Can you post a picture of the switch?

It only recently occurred to me that these were lacking a soft start. I was kinda thinking of devising something, but heck, I'm not gonna try and reinvent the wheel if EchoWars already has a design.
I don't have a pic of the (disassembled) switch, but it is a TV-5 switch, P/N SDU3P. I've dug around the usual suppliers, and I couldn't find anything that would be close to a direct replacement. But like I said before, I haven't made it a major priority, either.
I have to say, though I don't think the 16.5 is the greatest receiver I have, it was the first one I ever had that made me rethink the whole receiver VS separates argument. Nowadays, nearly every system I have uses a receiver, and I don't feel like I'm missing anything.

congrats Tarior. is getting a on/off switch a daunting task on these receivers???. I just bought a 16.5 last week off Ebay and its being shipped today ... i have everything crossed but my eyes hoping it arrives safely. Can't wait, after hearing my 6.5 and all the accolades from this place....

Hey 2020, looking forward to your opinion/comparison of your 16.5 with your CR-2020.

You bet, I will comparing it to everything I own. but I am betting that the Yammy holds its own against all comers

You bet, I will comparing it to everything I own.

Great - can't wait! I've owned them both so it will be fun to compare notes.

When you get it, please PM me the serial number for the Concept database, OK? Thanks.

All the best,

I'd be willing to bet it blows that Yammie right out of the water!

The last time I heard a CR-2020 was over 20 years ago... coupled to strange round speakers with marble tops...

That experience was "instrumental" in turning me on to the delights of marvelous musical fidelity..

Different speakers and intervening years, I could not seriously compare with my 16.5...

I love Yamaha sound, but I prefer the 16.5 over my R-2000.

Is this the switch? This one is in a Sansui G-8700DB. The G-9700 uses the same one. That expands the number of doner units a little. The smaller G-x700 receivers list a different part number for the power switch.

No, this one is a duplex switch. It has a large body with four pins behind a small body with six pins.
Actually, a fellow AKer may have the correct one, I have my fingers crossed.:sigh:

 

[LBPete]

That's sounds like a completly different switch. I posted the one in the picture because it is marked TV-5.

I found the thread where EchoWars posted a circuit diagram for a soft-on setup. However, the image was not displayed--there appears to be a time limiter to conserve bandwidth.

If somebody re-posted that, I'm really interested in performing this mod.

Thanks!

It looks like both EW's and CDfixer's soft start schematics got lost in the server crashes. I'll talk to CDfixer and ask him to post it again.

The Concept 16.5, without a soft start, sounds like a good prospect for a cheap surge protector type switchable power strip. Using the expendable surge power strip as the on / off switch will make the Concept 16.5's closed power switch a fat piece of wire that should last forever.

That was how the PO of one of mine handled the junk switch.

I hadn't known the 16.5 didn't have a soft start. It has been well packed since I moved and is being saved for a later day. It is still my favorite receiver. I am, though, a separates guy. When the day comes, though, to downsize everything, the 16.5 stays.
