I really appreciate the tip to Wfret. I went through the signup process for MIMF and ran into a couple issues. First, the site rejects requests for access to downloads if you're using a VPN service, and we all should be. Second, Wfret is a zip file containing an exe file that works on Windows machines; I use a Mac.
That said, the site is full of great information on just about anything one might need to know about instrument repair, care, building and more. Thank you for telling me about it.
