Fixing a Fostex R8 that would not play and wind correctly; but a problem remains

I like your choice in music!

Hello Sir,
I wanted to thank you for your work of archival on your website which helped me to find documentation on a calibration tape I found which is the AGFA Bezugsband 9,5 DIN 45513.
I didn't have any papers in the box as you did!
I was really surprised to see someone having this old of a tape with the exact same sitckers I have too :)

I was wondering wether I could use this today as I don't have any 3.5ips calibration tape but I have no idea what the reference magnetic flux is nor the equalization but I assume this would be IEC (CCIR) since it was made in germany?

Cheers from France,
Martin

Hey Philip, How exactly do you remove the audio cards from the R8? You've touched on this in the blog, but it's not totally clear to me - is it just force? Mine are sitting so tight, and I also can't find any info on this..

Thank you!
