Hi !!! I read the entire forum, but I did not understand, did anyone collect SD2000 or not?

Where is the track list

used a MAT12 in mine ..just after they had got manufactured ..

thank you detectormods

Replacement for LM394 you can use 2SC1583 it has lower noise and matched with gain of 500, much better than AD787 on +5 -5 as the collector resistors inside the AD797 are 12k ohms, you will never get a real low noise figure.. I know what the book states a low nf but 10 volts and 12K series resistor will not supply enough current to get rid of 1/f noise or reduce popcorn noise. Run 3ma through each transistor to get the lowest low frequency noise figure and a higher F/T as well.

Hello
I am about to make a digital version of SD2000, What i need is a driver which will drive a +-5V from 5V so logic level driver. I am about to use ATMEGA328p or if i run out of pins i will use atmega2560 the reason is because those controllers support arduino ide and it will be easy to do a software. I found a MC14504B chip but now i am not sure how to connect it. Can someone with more experience help me with that ?
I know that chip is used in SD2200 so if someone have SD2200 it will be really good if it can check.
I can use generic transistors to do that but it wont be too good solution.
If someone is willing to help it will be great!

hi friends. how will I do offset tlc27m7 3pin gnd test point tlc27m7 1-7 pin. continuous voltage is changing. why could it be.
Do you watch the video
