STATUS UPDATE: TKD has confirmed the GB order including the pots with extended shafts, and started production. So now we wait  

I might be able to make it work. I decreased the pad size a bit on the 2500. Slots are defined in milling layer 46. I will need to switch the sections of the 4CP601 to the 4CP2500 since the 2500 overl

So, there seems to be competition in the market; behold the TKD-401. This looks like stereo only, but I bet between channel tracking is very precise, as long as you keep going straight.

I'm looking at the TKDs from the GB and comparing them to the last 10k one I had from when I bought them in Japan myself. My old one has a different marking on the right side (looking directly at the shaft): A10KΩ. The GB ones just say 10KΩ. Should I be concerned these aren't logarithmic audio taper?

Well, log audio taper is what I ordered and I'm pretty sure that's what we received. That said, while I've tested all pots I only checked the taper on the first few (which was log audio); the rest I tested for channel imbalance only.

If you want to make sure yours is log audio, please remember to test it as a voltage divider (the ladder construction puts resistance measurements off the log curve). Hook it up to a small battery or similar and track Vout from the viper. Should it be the wrong taper, let me know and we'll sort it out.

I don´t know if it will have good channel tracking because, it is after all, a lower grade of the tkd 601 . Lower grade products are always worst ...imagine if they haven´t proper balanced alimentation..it will be even worst :lol:
