Sunfire Amp LED Modification
« on: October 02, 2011, 08:19:54 PM »
I began the mod to put a RadioShack LED in place of the constantly burning out lamp in my Sunfire Cinema Seven Signature amplifier. 

LED values:

[size=85]Intensity: 350 mcd
Wavelength: 465-470 nm
Viewing angle: 154 degrees
FW current: 20 mA
FW supply: 3.2V (typical), 3.8V (max)[/size]



Used this site to calculate the resistor needed to match the LED up to the circuit (supposed to be 12 volts DC):

Interesting; when I got the amp back apart & checked the voltage across the light nodes it read 14.78 volts DC; considerably MORE than Martin's measurement of 12.54 VDC.  I hope my 560 ohm resistors will be sufficient.....

Anywho; got it apart, modded, & back together in less than 30 minutes.  This is an EASY job if you know ANYTHING about desoldering/soldering a printed circuit board & have a decent tiny-tipped soldering gun.

Very Nice!!
I am confident that an SL-1200 is capable of outperforming turntables of much higher expense with minor modification.

Very nice and blue is my fav color.  Blue LED seems to be "in" with electronics and computers but some colored LEDs seem so bright and blinding.  So far the only color I've been able to really tolerate is the greenish yellow, which is sad because I hate the color.  I find blue and sometimes red really need muting to tolerate how bright they are.  I'm not sure if anyone else experiences the same thing, and my eyes are really sensitive.

But anyway, it looks cool :)

Could this mod be done to the meter lights on my MAC 352s?  Audio Classics wants $400 for their LED mod.  I should note it's drop in ready.
MAC C-46 pre, MQ 108 eq, MC 352 amps (2), MR 78 tuner, MCD 500 CD, MPI-4 scope, LS 352 speakers, Sony HDR-F1HD AM/FM/HD tuner, Denon DRS 810 cassette, Denon CDR-W1500 CD recorder, Music Hall MMF-9 w/B&O MMC2, Revox A-77 R to R.

You need to know what the voltage is on your regular lights & how many there are. 

Then you can determine what/how many LEDs & what resistor size to use.
