As I said above - the myth of my easy replaceable tubes for my MF channel got evaporated.  Sure, it is physically possible to plug in those 2A3, 45 or 4V tube and they all will work fine but Macondo will not tolerate it. In fact getting now the proper sound from Macondo running MF with YO186 I can clearly see what shall be my next step if I wish to do “it” methodologically appropriate. I need to define what would be this “it”. “It” for me is not the discrimination of tubes but learning to which degree my option for DHT in MF would allow me to mitigate sound. I know that all DHT tube are different but the key is to make my DHT by the means of other Macondo channels, to sound THE SAME (in context of all 6 channels) and they to see what those different DHT will be able to do while they all show off the same sound in context of the Macondo.

So, far I have found the interestingly–proper operation condition only for YO186. I do not mean the operation point for plate but the operation condition in Macondo. Those operational condition imply a very precise balance of

1) MF output volume (.25dB precision)
2) Tweeter output volume (1dB precision)
3) Injection Channel output volume (1dB precision)
4) Fundamental Channel output volume (.25dB precision)

I think the best would be to build up a little chart where I would mark the precise setting for each type of tube that would make it reputable and predictable.
