What is the "best" of the 5881 Tubes.


I have not had much experiance with the 5881 series of tubes. I have used only KT88/6550-EL34-807's..on and on, but my new incoming amp has the 5881's (Onix p3).

Any ideas ??

I would like to think that there is a "magic" bowl that is always filled with new (and replacement) amps at AV123. As reality may have it, however, we are perhaps Guinney Pigs stuck in a tub of volts.
Being the dumb A that I am, I have the honor of using the "new and improved" version of "WebTV". It will not allow me to access the "Melody" website. ... Just about, but not quite. I "can" get on the "Euro." version, but it is in French (or something like it).
Melody (in it's own right) is big Doo-Da in Europe. Melody makes (or engineers) a gaggle of amps (plus some other candy). They must make amps over in Australia to keep their minds off the sharks. Although I have know some sharks that were Audiophiles (check under "Feedback").
I now have 2 quads of 6L6's coming in. One quad is from JJ and another a China Electron. I'll start at 1.15 Volts to 1.4/5 Volts. I will understand that the lower D Volt D higher D Ampre (say Ohm-me). I just don't want to take out the resister that is there (just waiting) for me to do that.
well no luck getting a response from Melody ....not sure what to make of it ? I was told that if a bias circuit was a 'good' design then it would not allow you to go past the point that it could not safely sustain ....but who knows what kind of a circuit we have ...??
Bernard991,

I put the Bias question directly to AV123 this morning (by Email). I will relay their response. I also suggested that they take some time to follow our threads (here on Audiogon).

we will hope for the best Tubby but for some reason ...they are silent on this issue ????
let us know ...
Bias issue for the 6L6 (GC) is resolved.. !

According to the techs at AV123 (in their reply to my Email) they have suggested that the Bias voltage remain the same as for the 5881 power output tubes. That Voltage is: 1.15VDC. Since the makeup of the 6L6 is basicly the same, and the output is at the same level, an increase in voltage would not be justified. Soooooooo... There we have it 1.15 Volts.
As a side note, I rec'd my JJ Electronics 6L6GC's and I immediatly stuffed them in the SP-3. I set the Bias Voltage for a Buck-Fifteen. I then waited for the explosion, molten glass slivers in my eyes and nasty noises from my schredded speakers. None of all that, BUT there was plenty of the "needle wabble" and "the Numbers Dance" that indicates a journey ito "Tube Ocillation". I just cant spell at all today... any day actually, but I am really having tough time with it today.

Hey Modereator...... SPELLCHECK (please).

Anyway, Out go the JJ's. I still have a Quad of China Electron 6L6's that came with the deal, so when I get my nad's back I'll give them a try.

All for now...
