Out of curiosity, when you had VdHul retip in the past, did you provide him with information on what arm you are using? My understanding is that he tunes each cartridge accordingly. (I had a higher output VdHul years ago that was retipped, but wasn't using it in a linear arm).
There is a thread active here on the 'Gon now about linear arms that has a lot of good info on the ET2, tweaks, etc.
I have a Kuzma Airline, and just sent my cartridge (an Airtight Supreme) off for a retip. In the meantime, I bought a freshly retipped old Monster Genesis 1000, an entirely different sounding cartridge from the Airtight, to use as a stopgap. One thing I have observed-- the Monster is more of a medium compliance cartridge compared to the Airtight, and in some ways, I like its tracking and compliance behavior better on the arm due to the horizontal forces at play.
If you do retip (again), you might raise with VdHul the fact that you lost the stylus and have been a repeat customer for a long time. He is not getting any younger, - i think he's near 80, isn't he?-- but he might help you out. Good luck!
