I did along with the ion trap. Like Bob, I was able to get it close but it was still soft. I got this on eBay about 3 years ago and it was sold as a drop in replacement for a 10BP4 but, you know, you can say anything on eBay. It looks like a 10BP4, feels like a 10BP4, is pinned out like a 10BP4, is dag coated like a 10BP4...but it doesn't just drop in as a substitute.
