Hey, nice LEDs! Could you send me by any chance your LEDs guy info?
Thanks
Great job done really like these led lightsI thought I would document the LED upgrade on a vintage Yamaha CR-420 receiver in case anyone should be wondering how it can be done. It really was a very easy and straight forward procedure. The hardest part is getting the replacement lamps, but I have two contacts who have been able to provide me with direct replacement lamps as well as LED lamps. For vintage replacement lamps I went here: http://www.dgwojo.com/ . For the peimar lighting lamps below, I contacted an individual who makes them. If you are interested, I can forward you the contact information.
I have found the 70's Yamaha gear suffers from very dim peimar lighting displays, compared to other gear. Here's how the original lamps looked on this Yamaha 70's receiver (CR-420). Very dim, I think partly due to the age.
Here's two pics of the original lamps exposed from their seats.
Here's how the LEDs look
First step is to cut the original lamps, making sure you leave yourself enough slack.
Here you can see the new LED wires (to the left) spliced to the original wires. Notice the shrink wrap ready to be moved over the connection.
Here's a pic of the connections soldered together. Again notice the shrink wrap ready to be moved into position.
And here are the shrink wraps in place. I used a hair-dryer set on High to shrink the wraps into place.
Finally, here are two shots of the finished product. In the dark and in the light. Much brighter and very unique.
I am thinking about doing the same with my Yamaha Amp and Tuner combo, but I think I will go with the White LEDs. I love the Blue, but I think I want to try the whites simply to keep the original look as much as possible, but much brighter. The project cost me about $10.
Please let me know if you have any questions or comments. :thmbsp:
Can anyone forward me the contact info for the led upgrade? Just got a cr-820....
I used White LEDs this time. I really like this better than the Blue one's. I got this unique subtle gray/light blue color, which is not too radical and really brightened-up the receiver. At first i panicked, because I ended up with BLUE lights again and then realized that I had to remove the plastic blue colored "lenses" which is what originally gives the Yamaha displays that weird green/amber color. I also decided not to insert the LEDs inside the pointer tuner display enclosure and instead placed the LED on top of the pointer enclosure secured with a strip of duct tape. The effect was a much brighter tuner illumination which spills to the left and right. IMO this is how these things should have been designed in the first place.
No mention of polarity?
If there's AC on those leads, the LEDs are going to go poof without a blocking diode in place.
Nice looking, but I'd go with Green for Yamaha. Leave the Blue to Mac and Sui.
