jolida 502b manual bias adjustment


owners of the jolida jd 502b, how you set the bias manually without losing all the skin on your hands? i'm lucky mine has the ez bias as well as the manual bias.

This may be old news but, this is what I use on my Jolida 502A. It is a Bias Rite model #BR-4 by Weber. It shortens the bias time and allows you to make very accurate bias settings and compare each socket to make they are all the same at the turn of a switch. The test points on these amplifiers are not very good in my opinion. I love using the Bias Rite it has worked very well for me.
I'm not overly concerned. It's just an easier method that works for me. I don't have to hold on to probes with one hand while trying to make adjustments with the other hand. This way I can leave the amp where it is in my rack and make the adjustments. But hey if it works for you that's great, it doesn't for me that's why I chose this approach.

Do you have the 502B and if so is it modded. I have a 502A that was modded by Response audio and I love it. I can only imagine how much better the higher end tube amps sound.
