Gentlemen, this is so wonderful! Those of us who have the amp will have more people to play with!!
GG, I am really interested in the hidden stock your seller may have, I am really looking forward to hearing what he has as am I looking forward to seeing your experiments with the pins "Heath!"
Bmichels those variations are just my preferences.
What I am really looking forward to is what your preferences in tubes and combinations of them are. For me, the way you have listed them are the way I like them.
As to the quietest, well, it is short of a crap shoot as remember, they are all NOS so there may be variances as they may come from different batches and so forth.
What I will say is you will most certainly hear a ting ting sound if you tap the case or turn the volume knob, this is not microphonics! It is simply the sound of the very fine elements, I have heard it in every tube I have listened to and even in very expensive amps like Audio Note and Nagra it is quite normal from what I can gather.
Having said that some do it to lesser or greater extents but it usually quiet's down after burn in considerably. For me a quiet tube is one that does not make the sound like tissue paper being scrunched! And that is where the crap shoot comes in!
I have two sets of Mullards out of the four 1 scrunches but again, it does tend to lessen with use but I have found it to be intrusive to the music in quiet passages. It can effect any make as well.
Having said that I have yet to hear a German of French tube make that noise and in my experience those are the most silent tubes I own.
So, scrunching sound not so great but it can burn off with use, tinging sound not a problem as it is only present if you tap the amp or turn the volume, actually, some of the airiest sounding tubes I have ting!
Hope that helps and I am so looking forward to hearing the new owners thoughts, well done all of you!
And lastly, thank you GG for all your sterling efforts on tracing tubes, inventing doohikies to clean pins and all the research you have done on information on tubes.
