Salas you are a moderator does that mean that you can make changes in how things are organized on this site?
What I want to ask you whne you have a thread like john curls blowtorchamp with its 800+ pages I really cannot read them all that is simply to much for me. would it be possible to have the pagenumbers, that normally appear in the upperleft corner, be coloured in red or some other colour, when the page contains crucial information in this thread?

This is webmaster stuff. Moderators regulate the community attitudes mainly. The site is going on new format soon. I don't think that there is content evaluation software that can judge if JC wrote something crucial or less crucial for instance, but when the new format is up, maybe some suggestions can have a way around them. There will be lively discussion about options when ready I presume.

At some point I've looked at the aikido concept with some care, and applied the idea to a tube buffer for a gainclone amp I built. The assumption is that each amplification stage gets some power supply noise (ac component). My understanding is that it taps that psu noise and it applies it with opposite phase and appropriate magnitude such that the noise is effectively canceled. IMHO without a scope to adjust the components for this cancellation to occur it is difficult to get a benefit. Moreover, why would one use it in addition to a good voltage regulator? -- it adds roughly two tubes, a couple of resistors, and a capacitor to each stage. Even if cost was not an issue, one expects quite a benefit from adding so many components.
However, my understanding of the aikido concept is that it increases the circuit's psrr, which a good voltage regulator can do, but I don't really see how it deals with variations in voltage due to sudden per stage current draws, since it does not have a "reserve" of current to give to the demanding circuit, as a shunt regulator does (the shunt will shunt less current, in effect redirecting this "reserve" current to the load that's asking for it). So it seems to me that a good shunt regulator would trump the aikido.
Just my 2c.
up and running
Got the last bits in and . . . it's alive
First impression is an absurd dark background and very detailed music.
The overall tone is lacking highs but that is common with new caps I think.
As you can see I'm not much of a metalworker, functionality reigns.
I'm under the headphones for the remainder of the evening
One thing I'm uncertain about, that's connecting the shielding of the pickup audio signal. I recall reading not to connect but that gives instant hum. Connected there's no hum at all.

An externally hosted image should be here but it was not working when we last tested it.

I robot!
Yes, nice different one!
Dark and no hum (you do well to connect the wire's shield) means success! Let it burn in, and if the combination of chosen materials in conjunction with the rest of the system still leaves you with a craving for more sparkle up high, there are many ways to tune. Keep us posted. Initially see if the 881s sees 275pf in total or less (MMs lack highs if not correctly resonating on capacitance), and the VTA. Congratulations for your build.

I bet you have Grado headphones inside your signed AGV.
