dt50 bias probe points

[hichembell 2]

Before taking my line6 DT50 To a pro tech for biasing, I would like to collect some information first. 

checking on google and youtube, I have found a step by step  guide to retube and bias a dt25 w combo: 

 

 

 

 

 

on another topic hee on line6 forum, it is explained that in order to bias a DT50 one needs to use a dual bias tester  : 

 

"plug the bias tester probes into the power tube receptacles of the amp, then plug the tubes into the bias tester probes which look just like the bottom of a regular tube. Basically, the power tubes are plugged into the bias probe which is , in turn, plugged into the power tube receptacle (they are stacked on top of each other)"

 

 

my question is: Does the DT 50 owns the same 3 holes for the test probe points and the hole for the bias adjustment like a DT25  or is it different in design, in this case, it is a must to use a dual bias tester to get it biased? 

 

In other words, does the DT50 combo has such probes and holes that enable to bias the amp without using a dual bias tester :

 

 

 

I would like to inform you that I live In Algeria and there is no line6 shop or a line6  authorized repair, otherwise, I would directly take to such a repair center. My friend is a professional electronic.  engineer. He already repaired my DT50 and already changed its power transformer in the past. So, i would like to collect for him all the info, describe the procedure to him so that he will do it for me

 

thank you in advance.
