It is very nice and indeed and
under normal circumstance you will not need any permanent multimeter. It is for sure nice to have it when
you put a new 6C33C in use as plate current run wildly while the new tube is
burning in. It is still OK to do it with no multimeter. What I do is what a new
6C33C is in I set the plate current for 100mA and let it to burn for a half day.
Then the run out of the current become less and less and I set it to ~150-170mA
for a fully heat up tube and run it is it for another few days of listening.
After 20-50 hours on the tube I set the full power on it.
I do feel however that multimeter
is very useful what you have multiple channels and small kids in house. They
tend to turn anything turntable and if I arrange the controls on Milq after I
become a dad then I would put controls at very different locations.
Anyhow, it is kind of special pleasure to see the Melquiades
built out there. It is not the ego things, just a pleasure. It is 6AM in Boston,
the Sexy Amy is sitting in our library, playing with her computer and drinks her
morning coffee. I called her and showed to her the picture of your Milq, with Bruckner
records on backdrop and my schematics. She was very distinctly purring….
PS: a question. I see that the internal wall of the amp covered
with some kind of foil. Was it intestinal? Is it a regular Aluminium foil? Are
you planning to do extras shielding by it?
