How much Your LED voltage?

   

Just share about testing of LED voltage, many friends ask me how to check voltage of LED, then I make simple tool from 8 dip pin converter, 1 K resistor and alligator clip for holding the pins / check voltage with DMM. Hope this thing useful for matching LED or J-Fet .

Original SANKEN's Transistor For "The Red" Project!!!

     I get this trannies( Sankens) from Surabaya. I'm sure that sankens is original, from the marking and from trusted seller. I double check again the marking with original ones form sanken / diy sites. Well, we will see if i place trannies on my power amp red pcb's. :D . (pair of 2SA1216 and 2SC2922).

Little LM1875 Amp

 

This is my simple version of power amp based chip amplifier LM1875, the pcb's small enough to fits small parts and ic LM's.This chip amp LM1875 is NOS, i get them on small electronics shop in small city, small budget friends! hahaha. Minus from pcb is input capacitor, i will add later / separately with close track or solder directly on input female rca. I've been check and sounds is so so...dc offsets not checked / later.
