Not at the moment unfortunatly!

5) Sure!

Correct, also shape 1 does what VH4 does when gain is maxed out

What I mean for topology is the basic circuit, and the main "topology" difference between MK1-VH4 etc.. to MK3 and current Diezels is the variable gain is later in the circuit and the previous one is fixed, so swapped. VHX have the capabilities to do both the old style and new style thanks to...

1) They are +/- 0.5 offset from the presets, still clamped at 0/1 range. So if preset is 0.5 and and global is at max, the result will be 1. If preset is 0.75 and global is max, result is still 1. 2) Yes 3) DSP for the different filters and resistor/capacitor network on the load for the...

Just wanted to clarify most of the investigative work: VHX is just like all the modern Diezel lineup, so same circuit topology as Herbert MK3 and Hagen, gain pot is moved 1 stage upwards. VHX has also additional gain like control on the VH4 earlier in the circuit, that's is activated using...

I'm afraid it's hard to get it without a tube (and each tube brand have it's own) as the tube has some impedance on the high frequency that are dependant on the gain and the load, so you would need quite a bit of components to get that right. As for the simple the input stage (without taking...

Yes all Diezels have the same input impedance, VHX as well, higher than 500K but lower than 1M

Hi, it's pretty simple build so a schematic should not be needed for a tech for simple maintenance, just replace the cap with same value/voltage and it will be ok!

Yes the loop are completely independent, and works in series as a whole. So LOOP A in 5th slot will be before LOOP B in 6th slot.

All tube swap require biasing, even same tubes and same brand!

Not with a Columbus, however if you engage the auto tuner it could work if you make a mute preset. You can make a mute presets by having an empty FX loop assigned to FX.

Right, when you increase a lot mids and mid-scoop you get something very unique that is both pushy and scooped at the same time!
