Dear @wolfie62 : Now I own that ADC in stock condition. I posted a thread of the ADC 26/27 original status where I made tests comparisons against top today LOMC cartridges and overall in my room/system me and the owners of the today LOMC cartridges been in agreement that that Pritchard design is just superb and could outperform any other cartridge.
I know that you prefer the 10E MKIV and is ok. I have the 26 with 3-4 replacement stylus and now that you brougth here ADC name I will send to an update with boron cantilever and maybe Shibata stylus shape or VDH and yes with the length cantilever of same dimension than the original aluminum one.

Unfortunately for you, the ADC 25/26/27 carts are no match for the 10E MKIV. The 10E-4 came out after those carts, and just before the XLM. The 10E-4 was a test bed to prove Pritchard’s latest development in coil design and coil poles design. The improvement was used in ALL subsequent designs from the XLM to the Astrion. Your ADC 26 and 27 lacks this key technology. I used the 10E-4 with NOS R-26 and R-25(1) styli. It’s the very best of the very best ADC made! I still have 3 NOS of each styli. The styli for the 25/26/27/10E-4 are identical except the original R-15E was a bonded elliptical, not nude.
But you will never achieve the level of performance with the 25/26/27 cart bodies as the 10E-4, regardless of using a retipped stylus. They all lack the fine level of control of the 10E-4. And the XLM to the Astrion lacks the sound of the 10E-4. So your getting a retip won’t raise the performance to the level of the 10E-4.
I did the retip myself. I bought the boron rod and diamond on-line. I have a fine metallurgical microscope and alignment reticles on one of my eyepieces. But from here on, I’ll use Joseph Long. It was an exercise in patience. I used a worn R-15E stylus and cut the aluminum canti where it enters the armature. Then secured the boron rod inside the aluminum sheath.
