Is rectifier tube arcing a problem?
@imhififan  wow, thank you very much, that’s a very clear diagram, now I won’t be worried of making a mistake. yes, I always want to learn more.  Does the soft start and diode compliment to each other, or I only need to pick one to do?

@imhififan  also to make sure, the diodes should be added at pin 4 and 6 as shown in the second diagram above, with the line on the diode closer to the pin, am I correct?

@imhififan good point.  I also have considered those points, especially I am not that technically inclined.    
Is rectifier tube arcing a problem?
@atmasphere thank you very much. A couple more questions: 1) is it able to tell from the diagram if there other rectifier that can be used and handle the current drawn by the 220uF capacitor? 2) is it necessary or recommended to change the oth... 
Is rectifier tube arcing a problem?
@atmasphere @imhififan  Yes, mine also has 220uF capacitor, and yes, the arcing only happens when the amp is turn on. After than, and if the fuse doesn’t blow, the amps sound fine. here is the wiring diagram of the capacitor and resistors. Wi...

@imhififan thank you. This seems something small and won’t change the sound. min the diagram, I need to add two diodes per tube, am I correct?

@dekay  I found that thread at the Steve Hoffman Forum.  Honestly, what being explained there is beyond my technical knowledge.  I like the idea about adding a soft start, but I need to take it to my tech to do that.  But do you think adding a so...

@atmasphere and others BTW, is there other rectifier can be used for this amp?  Such as a soft start 5AR4?  
Is rectifier tube arcing a problem?
Short answer is Yes, the arcing happens in both channel.     for the 5C3S, at the beginning, I don’t think they arc.  Then after a month, both tubes arc.  For the RCA, they both arc right the way.  For the TungSol, so far, only one arc.  And when...

It is a Audio Note Kit Interstage 300B monoblock.   Here is the assembling instructions menu.  I have it built by someone and have another technician to go through it, so, I believe it is not a built issue.  It is design for 5U4G.  However, the co...

Thanks for the reply.  Actually, my question is, do I need to buy another TungSol.   And if I buy another one, is there a way to prevent it from arcing.  For example, wait a bit longer (5+ mins) before restarting.  Or this arcing is caused by the...

BTW, it seems the arcing can developed over time.  Both the Svetlana 5C3S started arcing after several weeks.  Both the RCA arc right the way.  I just got the TungSol.  One of them started arcing after a couple hrs of use.  The other one doesn’t a... 
Coincident Statement Line Stage vs Jadis JP80MC vs EAR 868PL vs Aesthetic Janus
@sns  for the 300B, I tried the followings in both the 211 as driver tube and in the ANK: - Shuguang Black Treasure - Shuguang regular  - TJ Full music mesh plate globe bottle - Sophia Electric Princess - Elrog - Shuguang WE300B - Cossor (... 
Coincident Statement Line Stage vs Jadis JP80MC vs EAR 868PL vs Aesthetic Janus
@charles1dad This is exactly what I think. I understand each tube has a different characteristic. So, I bought the Modwright LS100 which use the 6SN7. Eventually, I choose the slightly more open sound of CSLS over the excellent tone of the Modwr... 
Coincident Statement Line Stage vs Jadis JP80MC vs EAR 868PL vs Aesthetic Janus
@sns @charles1dad  In my digital rig, while CSLS is not 100% perfect, but very close to.  I wish to have a bit more tonal density or weight in the music.  I guess I can try further on cables and tubes, or even match with other power amps.  Power ...
