Does anyone know where I can get this "porch light" for Nak RX-202.

[Huck]

Hi: I need this LED porch light for my Nak RX-202 cassette deck. Not sure if the 303 and 505 use the same one. I have a pic here! Thanks, Huck

Let's see the other side. You may be able to read out the voltages and get a replacement at many LED houses online. Do you have the SM to tell you it's rating? Can you solder/de-solder if a new bulb was available?

Thanks! I put the deck away,as this is my "experimental deck".Will have to take it apart to have a peek at the other side. I can solder if I have to, thought maybe I could dig up the whole thing, wire and all! I can't access the service manual ( I should have downloaded it!!) as it is no longer available on the web-site I used to visit!! Who carries the "smaller" parts, as I also need an "eject" spring that goes behind the eject button! I had the cam belt off and it looked o.k.!! Man, that was some frickin job!! Put it back together three times ,as the "timing" was all messed up on the cam drive and the the flip mechanism! Now I know why that info's not available anywhere!! Huck*check*

Post it on nakstalks, someone has one. ESL has one, but you'll pay.

I have an RX-505 SM, and I don't know exactly how different these decks were. If they are similar, then the bulbs and such may be the same. Lemme know....

Thanks! I have a Service Manual coming for my 202, so I can look up the part# and compare it with your part#. This LED is red, where my other RX-202 has a white LED?! I will let you know once I get my SM! Thanks, Huck

[Scorpion8]

Sure, lemme know what you find out. Nak like everyone else used similar parts in many decks, so there may be some compatibility out there.

Thanks! Does your lamp go to the same place as mine, the red and brown wire with the plastic connector, right next to the blue cylindrical part(resistor?). Thanks, Huck

[Scorpion8]

Huck: did anyone on Naktalk answer your question?

[Scorpion8]

Do you have a DMM and some skills? If that lead shown above is the lead from your lamp, just pull it off, measure the voltage across the terminals while the deck is ON, and find a replacement lamp or LED of that voltage. If you have a choice, choose a higher current model so it's less likely to burn out since we don't know the ratings (yet) on your old bulb. If the lamp is an incandescent, and you want to replace with an LED, then we have a voltage and resistance issue, but swapping it with a like model would be fine.

Nah! I registered and I tried to post a question, but I don't think it went on the board! They work that site a little different than most sites... you have to send your question to some e-mail address! Weird! Huck

Yep... tha's the lead from the bulb! I have a few skills....it's not an incandescent! I'll tackle it some time...! Huck

Hi Ya Huck! I just registered on Nakstalks too. I haven't posed a question yet, but, it is a very slow Q and wait for an A, not knockin' the site, just slow way to find things out, after some posts under your belt, you'll find out who you would like to have discussions with and send that person your e-mail (maybe?) to get quicker answers, just a thought ,*idea* also THer macster knows a guy who works on NAK's for a reasonable price, maybe send him a PM or look at my BX-300 threads there's the guy's (Willy) e-mail there. Good Luck on the search, btw, I love the term "porch light" I had to think about that for a minute. I can be a little "dim" sometimes.

Thanks Craig: That term "porch-light" is not mine! I saw it somewhere and it sounded like it "fit". I guess the clear cassette cover could be the "porch"!?. Nice deck BX-300! Looks similar in cosmetics as tha RX lineup! Huck

Haha! :D out here we call 'em La' Nai's just like on "Golden Girls", I looked at a couple RX's and liked them even though the complexity at first glance scared me alittle, then the BX showed up on CL I was on it like a shot *devil* I got alot of help on TH *Hi5* and *hope* for now count myself very lucky, Tucson isn't overflowing with nice decks.

Hi: I turned it over and it looks like a factory rubber housing! I got 30 volts a.c. with an analogue volt meter...does 30 sound right? That's where the wires from the LED go,right where the screw-driver point is! Thanks,Huck

[Scorpion8]

Huck -- The RX-505 SM doesn't list the LED separate but as part of an assembly. However ....

Looking at your first pic and second pic.... 30 Volts is what's coming off the main PCB, not the LED voltage. That assembly that the LED is housed in probably contains a dropping resistor. Measure the voltage to ground at the LED base terminals where it is soldered to that assembly small PCB with the deck powered up. THAT should tell you what the ~operating voltage of the LED should be. Then it looks like any ol' standard Radio Shack LED can be soldered in as a replacement if you find one with the right voltage (probably about 2.6volts).

Try to save as much of that housing (whose purpose is to redirect as much light from the backside of the LED forward so it's not wasted) or you may fashion something from some grommets and tin foil.

Thanks! I did not see any resistor at the LED or board?! The one lead goes alongside the bulb and then goes straight down and is soldered on the bottom. I got the 30 volts at the bulb, not the connector at the other end. Another pic! Thanks, Huck

[Scorpion8]

Wow. You don't see 30V LEDs much. Are you game to try something? That looks like a common everyday RakShak LED. They aren't very expensive there, and it might be worth your while to pick up a few in different voltage ratings and starting with the highest, start replacing the dead one with new LEDs. It won't harm the deck if they burn up, but you may find that one is too dim, or too bright (and doesn't last long) until you get to one that lights up the right amount. Then just leave the deck powered up for awhile (~2 days overnight) and see if it can handle it. It ain't scientific, but it works.

PS - Can you provide some size measurements? It may be that (since the deck is older before technology advanced) that there is a dropping resistor internal to the LED. That would account for the higher voltage.

Also, compare to these ones and see if it matches any: http://www.ledtronics.com/ds/L300/

Thanks! My other Nak 202 that I use everyday has a clear LED(working)that I would like to change the colour of, so can I use some kind of paint,or magic marker to cover the clear LED to whatever colour( green, red,blue??) without causing heat problems?
The LED in my "spare" Nak has a red LED, which is longer(3/4") with long leads!.Can I just touch the leads of the new LED to the solder globs just to see if they light up, then I can solder them "permanently" if they don't blow right away?! Would the LED's be a.c. or d.c.?...I have no clue!? Thanks, Huck

[Scorpion8]

To change the color of an LED is simple. Several places (e.g. MAT Electronics; no affiliation) sell lamp covers that are like tiny rubber condoms. Various different colors, and you just roll one on. Or, and hold onto your seatbelt, you can use the much more scientific and technical method which is to find the right color Sharpie and go at it. LEDs generate a lot less heat than incandescants, so marker on the lens isn't an issue. The extreme technical difficulty is getting the permanent marker off your fingers from holding it while you attacked it with the marker pen .... :D

Yes, you can as the dead LED shouldn't contribute much resistance to affect your new one. That method won't tell you if it's going to last, but if you do touch it to the leads and it lights up REAL FRIGGIN' bright, then you probably have one with too low a voltage and, as they say in Blade Runner: "the candle that burns twice as bright burns half as long, and you have burned oh so bright there Roy"

Thanks! I would prefer the much more scientific method! MAT want a minimum of ten to be ordered, that's too many for me, so I will get a few color markers! Thanks, Huck

[Scorpion8]

Always good to have a few on hand if (a) you do much tape deck or receiver work, or (b) if you're "small" :D and sexually active ....

[Scorpion8]

Huck made NakTalk and got an reply already. Thats one I never figured out.... how do some people get to see the questions before the next day? Ask-and-reply was always a 3-day adventure to me....

Anyway, Huck? Looks like an LED to me. I don't know if the responder had the right bulb in question.

Yeah!! I got scolded for putting in animations,which must have went in automatically when I posed my questions. I have about four same posts, but with no text! I don't "get" that site at all! Anyways, I'm goin shopping at Radio Shack ("The Source" in Canada) for a handfull of LED's of different voltages and amperages and see how many I can burn out!! Later, Huck

Any update, Huck?

Hi: I just received my service manual and it seems that this "lid lamp", what Nak calls it is in fact a 12 volt 70 ma axial lamp. Seems that this one I want to replace is not the original part! I contacted a few Nak refurbishers and they don't want to part with any original lamps,cause they are nowhere to be found! I could try a 12 volt 60 ma Radio Shack lamp,but I am concerned with it creating too much heat for the rubber holder it sits in. Thanks, Huck

Heat in this case is W= E (12v) *I (.070) ref
The replacement would be W= E (12v)* I (.060) sub
So actually, you would be drawing less heat. What you can do is to set up a test mule and run the 12v through the lamp without it being installed in the cassette deck. You can put a piece of tissue paper (Charmin) over it as a heat indicator.

Thanks! I may try that! I found this one: http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=070-280, but it's 100m.a. . I think it would be too hot for the rubber holder! Thanks, Huck

A bit of research may be in order. I don't "think" that these LED's get "HOT" as we think of hot. We may be thinking of hot in the wrong way in relationship to what consititutes hot in the LED world. One of the reasons for using these items is that they are cooler than incandesant lamps and such. Now having said that, I have reached the end of my knowledge on this.

Good luck

Thanks, but it turns out that it is not an LED, but a "lamp", which I think produces quite a bit more heat than an LED, which is what I "thought" I needed, based on the one in one of two of my Nak RX-202's. One has an LED,which is not a factory part, and the other 202 has the 12volt 70ma axial lead lamp,which is the factory part. I'll get there sometime! Thanks for the help! Huck
