Technics SL-1300 Blue LED MOD

I changed my Technics sl 1300 regular Orange colour strobe light neon bulb with Blue LED 60 Hz.

[@dayvancubensis]

Does anyone have a tutorial for this? I just got an SL-1300, I have a bit of experience with electronics and soldering so I think I can do it. But I need instructions

[@pinarellospeedracer]

There are blue LED kits made fore the Technics SL1200 that will work in the SL 1300

What a beauty!!

[@frankjanssens1877]

where did you get this led , i want to do this to my sl 150?

[@djjammindave]

Hey boss! share your knowledge!!! where did you purchased the light bulb??????????????????simple question simple answer!!!!!!!!!!!!!!!!

[@parasrajora9499]

Jammin Dave this is not simple purchase and replace thing these are 4 blue LEDS which is driven by 60hz generating circuit. 60 hz pluse generating ic is purchased rest is self made.

@Jammin Dave.. the idea that you need an IC that generates 60 hz timing pulse to get a blue stroboscopic effect is total Bullcrap. do not believe all things in the net, some people just needs attention. you just need to replace the original bulb with an LED with a 10k ohm (this value differs depending on what LED you used, just google it) resistor to protect the forward voltage of the LED. that is all you need. really. you ask a straight forward question, i hope i gave you a straight answer. the strobe effect comes from the dots in the platter, if it is turning at the right speed, you will see the right effect. the light is just there to illuminate the effect. have a nice day!!!

@@vicv9503 the AC frequency 50hz or 60hz (depend on region) was not giving stable dot hence i used frequency generator.

Can you tell me how you did it? Where can I get the correct led?

[@parasrajora9499]

hello, these are not just LED replacement because originally this turntable have neon bulb(shown in the video) as strobe light which works directly from mains AC frequency. you can also use LED on AC with suitable resistor in between but it will not be bright enough. i uses few things here. i bought Turntable Strobe module from www.tindie.com/products/bot_thoughts/turntable-strobe/ if its unavailable ask the guy for its he is very friendly and helpful. few modification require to run 4 LEDs at full power. if you want to know in full detail mail me i'll send you schematics or just ask the bot thoughts guy.

I have a SL1300 and want to do this, Can you still buy these blue neons? The link takes you to a blue LED. Did you shoot a video of installing the bulb? That would be helpful

[@parasrajora9499]

These are not neon bulb but LEDs running through frequency generator . i did not shoot the video when installing it but i can make video to show how it is from inside and its circuitry is but you have to wait as i am busy and dont know when i am able to shoot it.

Paras Rajora ok no rush, let me know when its uploaded

Hola, y cual es la resistencia adecuada. yo tengo una sony ps-8750 version USA (120v 60Hz) y puse una luz de neon universal pero no entrega los flash adecuados para controlar la velocidad en el plato. sera que en chile usamos 50hz?. tambien podria ser que la resistencia no sea la adecuada?. gracias y si me ayudas genial

[@parasrajora9499]

Muy probablemente su neón funciona bien. Es el tocadiscos sony que tienen marcas en el plato de acuerdo a 60hz por lo que no se puede poner ninguna resistencia para hacer neón para brillar a 60 hz cuando la entrada es 50 hz. Usted puede comprar el estroboscópico 60hz llevó la luz de en alguna parte y la substituye con el neón. O haz uno mismo para ver esto kzbin.info/www/bejne/f3e5iXRmoNWnoKs

@@parasrajora9499 Hi, I need to change the strobe light. Can I use a single led light? Any help will be appreciate.

[@atanasatahac]

Hey I've got a 1500 that I'd like to do this too. Can you send me the schematics too?

[@parasrajora9499]

You have to first buy this www.tindie.com/products/bot_thoughts/turntable-strobe/ this is currently out of stock but ask the seller if he can make you one. If you got this ask me again for further schematic.

[@parasrajora9499]

Or you can buy any other frequency generator either 100Hz or 120Hz which is double of 50Hz and 60Hz respectively. I don't know how to make perfect frequency generator. How the current default turntable strobe light is working? Mine was showing squarish dots instead of perfect circular dot that is the reason i changed the neon bulb for this micro controller based strobe. If yours working fine you can you electric mains to light up leds too which then will work on frequency of your mains electricity.

[@atanasatahac]

Ah... okay. I've contacted the seller so we'll see what he says. I think my stobe is working okay, so maybe I'll try that. Your speed looks pretty stable, have you serviced it? My 33rpm seems to be either a little fast or little slow...

[@parasrajora9499]

I changed all the capacitors thats it.
