Hi Sir Lord Foo,

Could it possibly be full range speakers?
Those are just too big of an enclosure for a midrange.
But Sir kefq can enlighten us.

fellow members,

i would like to ask for your inputs on where to bring my sansui au-6500 for check-up.
thanks in advance!

sansutsut · « **Reply #2583 on:** Dec 12, 2008 at 06:32 PM »

Hi 2 all fellow PDVD members! Bago lang po ako d2 and this is my 1st post......

Meron po kasi ako Sansui Au-D607 na nabli ko last september.

Last week nagprorotect yung relay tapos blinking lang yung ilaw tapos nagkaroon yung right channel ng popping sound, ano po kaya may problema?

Mga Masters, HELLLLLLLLP naman po.....TY

Hi Sansutsut,

That is a good Sansui, in fact i have one.
Bring it to a good electronic technician,
before something of a major problem may occur.
That is a dual power supply Sansui model amp,
AU-D607, 70wpc.
My main concern when buying for an amp are the
output transistors.
Sansui usually uses Sanken or Toshiba.
Those transistors are hard to find nowadays, worst,
not available anymore.

Sir, how about yung ang tagal bago pumalo ng relay and yung output sound ng right ay mas malakas kaysa output ng left? Possible kaya sa mga leaky capacitors?

Siguro nga po tama kayo dalahin ko sa good electronic technician!

Sansui amps takes few seconds for the relay to activate, this is normal.
It should be about 5 secs. Longer than that, there might be a problem somewhere.
Well regarding the output sound, AU-D607 has a selector switch at the back, that
contact point may became dirty over time (preamp-power amp sel. switch) and may result
to problem to the output sound, Try cleaning it with a contact cleaner.

Sir Nelson O,

My AU-D607 activated the relay mga 30seconds
to 1 minute.Nakita ko po yung sinasabi nyo na
switch at the back of my amp, pwede po pala
maging separate power amp and separate pre amp?
Wala po ba talagang jumper wire betwen
pre-amp out and power amp in sa rca at the
back, kasi po sa ibang amp na nakikita ko
ay meron.

Ty po ng marami ulit......

Nelson O · « **Reply #2588 on:** Dec 13, 2008 at 04:22 PM »

Yes, AU-D607 can be used as an integrated, pre
amplifier or power amplifier by properly setting the
selector switch at the back, the reason for not having
a jumper wire.

By the way sir ty and more power to you and sa M509.....

Thanks Sansutsut,

Yes, i'm the lucky (am i? hehehe...) owner of the all intact,
all original power output transistors (all Sankens) M-509.
It's a 200wpc at 8 ohms power amplifier and weighs 31kg.
My heaviest amp being the 9090db (24kg) before having the
M-509. You should see the vu meters in action! Fantastic!
Btw, about the fuse lamp. I think Raon is the best place to look
for those vintage electronic parts.

Regards

AU-a 507XR is the entry level of the XR series (1993)
60 watts per channel at 8 ohms
weighs 10.5kg
Alpha series are well designed and Sansui's pride
after the great solid state era of the 70's

Btw, when you said "lola"
are you referring to Little Chatty?

Ah, ok, you're referring to FJMR.
IMHO, every AU alpha regardless of the model
are well designed.
In the end, it is your music preference that will
determine your choice of amp/equipment.
Btw, do you have an AU-D707?

sansutsut · « **Reply #2601 on:** Dec 16, 2008 at 09:27 AM »

its a AU-D707F Extra sir.
wala po sir, dun din po sa FJMR yun.
audition ko lang pati yung Alpha na 607,
sa 507xr medyo ok yung pandinig ko.
pero sabi naka reserve na daw ung 507xr.
May nkapila pa nga po sa akin na
mag aaudition din sa mga Sansui's...hehehehe
Puro AVR po halos ang andun ng magpunta ako,
kahit sa Little Chatty wala rin po maganda...

Hello po!.. merry xmas to all!!

I'd purchased 1 unit of PA for my audio setup. This was been made by Victor japan (110VAC from pier) and model is M-1100. I would like to ask a favor from anyone if you have any idea/s regarding this amp? I am also asking if anybody here has keeping a specs/diagram for this type of amp.. As I opened the console, it was been driven by a 7-pin power pack IC (STK-00125 product code). I tried to search on google & yahoo but this was not been displayed even the datasheet for this IC does not display also.

Need everybody's help.. thanks for the support!!

That's home hifi power amp rated 80wpc @ 6 ohms. Current resale price in Japan could be found here: http://yackdb.s138.xrea.com/auview.php?m=M-1100

Hi Sir Sandawa.. many many thx for the info.. san kya pwd makahanp ng schem diagram ng amp na ito? even ung data sheet ng power pack ic wla na sa net. BTW, 80wpc @ 6 ohms/ 60wpc @ 8 ohms max tama po ba ung rating?
anyways, many tnx po ulet... God Bless you!!

sandawa · « **Reply #2605 on:** Dec 17, 2008 at 02:20 PM »

Mahirap humanap ng diagram niyan unless you'll email Victor Japan (JVC) and it's patient enough to send you an attached document. Yamaha Japan used to do that.

Reymer · « **Reply #2606 on:** Dec 17, 2008 at 06:24 PM »

Hi. I have this amp in my collection for some time now, Panasonic SU-V900. Not as popular as Sansuis, but I enjoy listening every time I hook it up. Matches very well with my B&Ws

sandawa · « **Reply #2607 on:** Dec 18, 2008 at 07:23 AM »

That's actually a Technics and a very good amp. Technics, Panasonic, National, and Ramsa, among others, are brands that belong to Matsushta Electric. BTW, Matsushta also owns Japan Victor and its international brand JVC.

Nelson O · « **Reply #2608 on:** Dec 18, 2008 at 07:47 AM »

It is 100wpc at 6 ohms
Weighs 21kg!

Dual mono design.
Now, that is an amp!
