While I wait for parts for a 2006 mod (capsule mount specifically) I looked at stripping a 2001 and doing (is it Marik's?) U87 front end mod. The question I have is the coupling capacitor. On the original 2001 this is a 4.7uF tantalum. On the U87, AFAIK it is a 1uF presumably also tantalum. On the mod schematic it is still a 4.7uF.
I'm inclined to go with the original U87 schematic, which is 1uF, and a Cinemag 2480 not a T13 for cost considerations. But would like opinions on the capacitor value.
The mod schematic is attached. C7 is the capacitor.
I am also going to replace the 32mm capsule with a 34mm K67 style.
