I have a great 72 Super Reverb. The filter caps have ben replace, it has been blackfaced. But 8 other caps were changed and the Orginal blue ones removed. They seem in great shape the person I got amp from gave them to me. I just dont see why he removed them. Isnt it best to leave them in. So, so I leave it as is or put the originals back in? Here is the ones he took out.
