Default Re: Are these Revox tape heads scrap?

Yes, the heads work but I haven't yet measured the frequency response.

The heads were filthy, really clagged up with tape shed and sticky stuff. I always use cotton buds and 100% pure alcohol (IPA), these images were taken after the initial wiping just to show the extent of the wear. They need taking out of the machine and properly cleaning now - I wasn't going to bother if they were scrap!

I have contacted Summertone to get them refaced - it'll make me happier to know that they have been properly treated!
