jolida 502b manual bias adjustment

did not mean to imply your method was inferior, etc... i was speaking to OP. just wanted to point out that the connections to spikes do not have to be rock solid to get job done. if i had longer tools it probably would be easier as a matter of fact but the probes can stay in place free standing long enuff to let go of them for adjusting slot screws. ntl, i think auto bias is a gret option, i wish that feature was offered on mine but it was introduced later on.

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.

Can anyone tell me where to find a manual- also there are four small tubes - do the 12ax7 or the 12at7 go on the inside or the outside tube sockets?

Have you tried contacting JoLida in Maryland about a manual (also your tube placement question)?

However, from the image here, the 12AX7s are on the inside.

I recently sold my 502p…a great amp that served me well for years. The 12AX7s are on the "inside" of the small tube pairs. I had a "Littlite" gooseneck light over the amp that I would hang the bias meter cables over to keep them under control when using the meter to check the bias, but burning my fingers was part of the ritual…however, the bias LEDs were very accurate and I didn't really need the meter.
