Take pictures of every section you are working on before you start and after you finish Very good advice. Especially when there is no schematic available!  
Question About Capacitor Upgrade in Tube Amp
I don’t see the need to excuse rude and obnoxious behavior. I was just joking around a bit to ease the tension. But to be honest I do not take any comments personally. Unfortunately there is always some character lurking around a forum who is ... 
Question About Capacitor Upgrade in Tube Amp
whatever you do….run new parts in before passing judgement…. This is a very good point. I have been running the Kt-150 based Muzishare X10 for a few days now. Maybe still only 20-30 hours on it since delivery. But the soundstage is really openi...

@charles1dad  I am glad that you see his point. I do not. He makes smug and arrogant assumptions about people he doesn’t even know.  They are just words on a computer screen. Don't get mad at some LCD pixels. Unless you are on Twitter and some...

Question About Capacitor Upgrade in Tube Amp
Yes too many amps right now. I ordered the Willsenton R300 and the Muzishare X9, X10 just in the past weeks with the intent of auditioning them and only keeping one or two. It is hard to decide before hand when there is nowhere to hear them before...

Thanks! I will take a look. I have watched a few of his other videos before. Seems like a nice guy in addition to all his knowledge.  
Question About Capacitor Upgrade in Tube Amp
From my understanding the existing non-polarized caps are silver film. I do not think they are junk but for a reasonable cost certainly am willing to upgrade them. So no love for the Mundorf Supreme SGO 1000VDC caps here? I had originally been th... 
Question About Capacitor Upgrade in Tube Amp
Thanks for the replies so far. Did anyone know if the .33uF on the B+ filter cap is just for noise filtering on the power supply or does it have any effect on the amp sound? I probably will just leave that one alone unless someone one here has so... 
what kind of power conditioner for front end?
  I use a Furman Elite 15 DM I. I feel it offers sufficient surge protection. It has 3 banks of outlets with separate filtering for each type. And it has displays to show voltage and current output. For around $400 on sale it is all I think I n...

Viva Tubes
