Technics SL-1500 schematic anyone?

[audiomatic]

Hello;

does anyone have a schematic of this player? Motor drive and PSU section are needed (of course the entire pcb isn`t that large).
SL-1500 MK-2 does not help (completely different), aswell as most of the similar models (SL-1100, SL-1000 etc.).

Thanks;

audiomatic

I've got an old but working 1800 laying around.
If you think this chassis might be the same I could do some measurements for you, I could give the Panasonic guys a call, whatever suits you.

Have you tried the Vinylengine?

Can't see sl1500, but maybe sl1700 will do?

schematic SL-1500

Hello Harald & Hugo;

thanks for your help---

@hugo: From the experience I made with a lot of other schematics I have seen, I have the impression that technics - in these days - could afford the luxury to design a different drive for each of the direct driven models. Therefore I appreciate your help very much, but I believe the 1800 is rather different... anyway, thanks a lot...

@harald: I didn`t know these sources... seems to be a lot of useful information in there, maybe I will find the schematic when using one of the site`s links (... for sure I have googled before asking here...), thank you anyway...

regards, audiomatic

I'm trying to fix up an old SL1510 and could use the schematic/manual for the 1500 series as well....I've looked around and no other schematics seem the same. All I can say is that at least, this model has no specialized IC's so it can't be too difficult to fix once I find the problem. It won't drive the motor...and I've cleaned/replaced/verified all the switches and potentiometers. I have a sneaky feeling the oscillator isn't oscillating...the things blows a fuse after 30 seconds of "ON."


Anybody got one lying around they could scan?

thanks,
micah

Hi! audiomatic !

Yes , I have schematic manual (service ), but it is in PDF file format about 5Mb.

Hello zeonrider;

well, 5MB should be no problem for my mailbox. So, if you wish to share the document, I would appreciate your help for sure.
I suggest that you separate the pdf into 3 or 4 RAR files to minimize the risk of any upload trouble.

thanks and regards, audiomatic

Check power supply. Replace old electrolytics.

 

[Boris_The_Blade]

Yea it was fixed a while ago...I first replaced all the 'lytics and then cleaned all the switches and pots...still didn't work.

Turns out then that a NEW electrolytic cap I put in was mislabeled or cam pre-shorted for my inconvenience... How often does that happen?!?! I put another (different brand) new one in and after that it worked like a charm.

I need a copy of this service manual, is there anyone who can email it to me? I am in the process of doing a full restoration on an old 1500 mk1 and this would be invaluable to me!

[Boris_The_Blade]

email me with your email and ill send it over this evening (it's about 5MB though so be ready for that)

 

[despotic931]

Thanks very much Boris! Email sent!

 

[paki976]

Could someone post it on VinylEngine or send it by e-mail to me at dantoni.fabrizio@gmail.com ?

Thanks,
Fabrizio

 

[despotic931]

Email sent Fabrizio!

Thanks boys, uploaded on VinylEngine for future reference!

Now back to the soldering iron.....

 

[paki976]

Ok, found ZD1 shorted and A720 and a A666 death.
Now the turntable tries to start but stucks in one position. If i give a push to the platter it starts to spins but after few steps it stop. It also moves really jerkly.

By now i substituted:
all of the 1s1555, also on the motor PCB
2SA720 by BC638
ZD1
OA-90
2SA666 with BC259

Any Help really appreciated (Justin?)

Thanks all and sorry for my English,
Fabrizio
