I beleive that I made the voice coil too tight, and it rubs slightly on the magnet. When the elmer's glue dries, it makes the paper shrink. Quite a bit.
I hope with slightly larger diameter voice coil that won't be a problem, and I get the desired efficiency. I can increase efficiency by doubling the number of turns (and turning it into a 16 ohms driver instead of 8R). That makes a slight increase in total mass, and a quadrupling in inductance - a significant increase in sensitivity.I also use a 8in 95dB Fostex. (FE204). :) I like it so much, that I do not intend to replace it. I am making the DIY driver for a mono setup, that I want to make as DIY as possible. I don't know if I can turn out a DIY cartridge, but it will use DIY tonearm, TT, coupling caps, and some diy resistors and transformers, chokes.... I'm doing this out of curiosity. Will take a while to build.
