What is the "best" of the 5881 Tubes.

Can anyone find an "open door" (so to speak) to the techs or service at Melody Audio in Australia ? I believe that they would be the ones to have the most expertiese in the Bia's and limitations of the SP-3. My only hesitation would be a gentle "toe stepping" on AV123 or perhaps causing a potiential problem between Melody and them.
However:
It is important for us (the owners and potential owners) to know the operational parameters of this fine amp. The "known" is:
5881's, 6l6's and KT66' all have different bias voltages (as: 6550 vs KT88/KT90).
(just cant seem to spell today). Any-who, It is the fine folk's at AV123 that should be saddled up to the boys down under to find a answer to our madness.

totally agree Tubby !
maybe this might bring some much needed information to us re the BIASing issue .....
its hard to imagine how there are no schematics out there ...what happens if one actually breaks ?

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).
