  1. audioguru replied to the thread B562 Vs B772 Transistors.

    The base resistor? Then the extra high current will smoke your PIC. Replace the weak little transistor with a logic level P-channel...

  2. audioguru replied to the thread Simple Mono to "Stereo" adapter.

    Thank you. My audio career was 45 years long and I had 4 employers. Two of them rewarded me. A few years ago my trained ear surprised...

    You really want to use a reactive suppy to avoid resistor power dissipation. There are ICs that can also do bbetter detection.

    If the max volume is too loud, you can split resistively.

    An engineer with a trained ear - audio was your destiny. I hope your employer knew how lucky they were to have you.

    Is it ok if I lower the resistor to 15 ohms.

  7. gophert liked audioguru's post in the thread Simple Mono to "Stereo" adapter.

    One day I was driving home from work and a song on the stereo radio began playing and sounding weird. I knew what they were up to. I...

  8. Suraj143 rated rjenkinsgb's post Agree in the thread B562 Vs B772 Transistors.

    Both transistors have a minimum gain of around 80. Changing those is unlikely to make any significant difference. The base drive...

  9. Suraj143 rated audioguru's post Agree in the thread B562 Vs B772 Transistors.

    32 rows of LEDs at 21mA each = 672mA. Your transistor is used as a saturated switch, not a linear amplifier so the base current for the...

    Wonderful information.every information is true.for the time being the only modification I could do is to change the 47R to a low...
