DIY Class A/B Amp The "Wolverine" build thread

When you get everything together, you need to make the adjustments with the top cover sitting on top. It took me most of a day to get it tweaked.

Perfect and keep an eye on it, it may change in 30 minutes or so. For this test, I think you are done. Lower the bias back down to zero and you are ready for your final power supply. Don't forget to remove the resistor in parallel with R17 before applying your final power supply. Also, how many milliamps was the 1st board pulling, write it down, the 2nd board should be close.

I'm glad you reminded me. I have to pull the IPS board to recover that resistor as I need to install it in the other channel. I lowered the bias back to zero. I believe the board was pulling something like 485 mA.

Thanks,

Ok, this process is similar to the F4 and F6 amplifiers I built. It's all about the thermal environment inside the chassis

There it is!
