way back in may --in this feedback section-
we had a thread about norm " Toshiba # 40 " ...
he brought a cosmetic and functional basket case-
to one of the nicest//best boxes in the world-
this month --he DID IT AGAIN !!
my Crown # 945 was a total disaster-
now its my all-time favorite box.
want to thank norm for another unbelievable
effort --his cooperation and talents are
valuable to the boombox community-
beyond words
custom made lamps by stormin normin
excellent stuff, im very happy for you IRA, looks like NORM is the man then
What an amazing effect, that is so cool.
Those are some SICK led's.......How many in total were used?

6 Total. 4 discrete LED's to illuminate the dial. 2 SMD LED's on kapton ribbon illuminates the meters and bleed through to simultaneously illuminate the tape counter too.
Here, you can see the 4 LED's mounted on the sides of the tuner dial:
Here are the two SMD's above the meter. You need to look close to see them as they are very small and are mounted on a ribbon glued below the dial and above the meters.
Here are the left/right view of the dial as seen when assembled. Looks rather factory installed, don't they?
Finally, because Ira's photos always leaves a little to be desired, here is a better photo of the finished product. You DO NOT want to see what it looked like to begin with.
Wow, that does look factory, very discreet! Was that ribbon already there, or did you add it? Was there originally nothing but an empty gap along the edges of the tuner scale?
genius
i can do that
very impressive indeed

The gap was there. All the LED's were added including the ribbon. The LED's were chosen based on where they were mounted. I felt that the discrete LED's on the sides would be better but to illuminate the meter required a very thin illumination source and so standard LED's were out of the question on the meters and thus the ribbon mounted SMD led's were chosen. The colors matched, although the operating voltage of the two different varieties were different so they are powered differently. The meter LED's had stepped down current from a resistor array but the discretes were sensitive to voltage fluctuations depending on whether battery or AC operation and flickered when boombox is pounding hard, so those are powered by a custom made adjustable voltage regulator. So the brightness can be controlled by adjusting the regulator. A hidden switch was also installed to allow the boombox to be operated with or without the LED's to conserve power during battery operation. With the regulator installed, the LED's no longer flicker regardless of AC/DC or how hard the boombox is driven, as the voltage source is rock steady.
And those led's are vitually immortal, right? At least compared to old school incandescents. I usually prefer the "warm" look of incandescents, but can't stand it when they burn out.
