Bias test point question

Postby susomora » Fri Nov 13, 2015 12:04 pm

Hi everybody!
This is my first post in some years. I built this amp a few years ago and after relocating to a new city it has been sitting in a box for a couple years. A few days ago I decided to dust it off and bring it back to life. The thing is I didn't use the available circuit board... I designed and built my own PCB's based on the schematics. After resetting the feedback I'm trying to figure out where to probe my DMM to fine tune my power tubes bias. I remember using a resistor's leg as a test point but I don't remember which ones... could they be the legs of R43, R44, R45 and R46 that are connected to ground in order to get those 350 mV ?
Thanks a lot in advance, can't wait to hooking it up again!

Go there and download the manual, it has the bias adjustment procedure you are looking for.
