Sansui g 7000 dial lights

[jason]

How do i install blue l.e.d. dial lights on a sansui g7000, and what parts are needed to do so?

Hi Jason
I don't know; but there are others who do I am sure.

Welcome

[jason]

appreciate that. i just had my g7000 restored, and the blue led's are the last thing i need to do to it

 

[speakerman1]

Jerry should be able to help. He did I know one LED mod.

all right, if anyone can point him in this direction, ill be forever grateful...thanks

 

[jason]

even my tech wasnt exactly sure of how to do it, but so far ive seen two of them online that were done like that.....pretty nice looking

DO they not fit in the mounting spot or do you need to know how to make them work?

I believe the LED's need a resistor tied in with them to get them to work right but I'm not sure of the value of the resistor.

 

[speakerman1]

You need to get the voltage to them. I just got an email the other day they had them on sale. Did you buy them yet? Being a member here does have its rewards. LOL

Hey Jason, welcome to the forum!

Different receivers, amps, etc, have different voltage and mounting considerations. I haven't had a chance to look inside a Sui "G", so first if you (or anyone of ya's here) can describe what you have as far as the stock lighting, maybe we can go from there. I did my own led lighting on my PL 700, but that was specifically for "it" alone.

Pics welcome too.. Let me see what we're up against.

Sorry guys, was asleep for a bit there lol, and yes, i need to know how to make them fit, in the mounting spot, and also how to make them work....i can put up some pictures in a little bit, ill just have to get the ol g out of the cabinet that shes nestled in {shes heavy lol}

 

[jason]

ohh, and no, i didnt buy the lights yet

You need to rectify and filter the AC that is running the incandescents now. Incandescents run on AC or DC. LEDs are DC only as they are low voltage diodes (although some web marketers run the LEDs off AC with a limiting resistor, it is not good design practice to do so). In addition to turing the AC in to DC, you need to install a series resistor in line with each LED to limit the forward current to no more than 20 mA.

Send pictures if possible.

Yep, that's exactly what I did with the PL. Pic of the PL lights? No way... too scary lookin' . BUT... I'm pretty sure we can come up with something for the "G" here, no problem.

Funny thing you should mention about the rectifier.. I was just thinking about that yesterday. Is it in forward or reverse bias when an LED will "light"?

 

[laatsch55]

Well, you have a forward voltage drop with a max reverse voltage. I would say forward.

Yep, so if the PIV was high enough then with a resistor limiting the current, why use a rectifier? Just thinking.. why not? I guess if you can see it flashin' on and off 30 times a second (30 for the forward bias part of the ac) then that would bother ya... Unless the on and off many many many times is what will hurt it?

 

[Gepetto]

Forward current = illuminated.

LEDs are not rated for PIV as they are not intended for application as a rectifier. If you do, you proceed at your own risk as far as the manufacturers are concerned. That is in addition to the 60 Hz strobing that Jer mentioned.

 

[jason]

just want to say i really appreciate all the help here, im going to get the ol g out of the cabinet sometime tonight and get pics up, wifey wants me to go to the store first...lol, life intervenes with pleasure again, but, i do think that you guys will like my rig

 

[jason]

this should help us figure the lighting out on the g7000

 

[laatsch55]

Do you have a meter??

 

[jason]

i dont have one on hand, but i could probrably pick one up tomorrow, i have a hardware store about a mile from me
