Default Re: Ferrograph 4A: Restoration advice needed

Thanks TIMTAPE. I read on here or Tapeheads yesterday about incorrectly zeroed tape paths causing the 'characteristic keystone pattern' of wear on the Ferrograph head, which is certainly what this one has. The thing would certainly benefit from a relap according to those instructions you sent, and from what I can see the base wouldn't get in the way of the process. I'll ask at Ferrograph World in case there is a method of getting the base off without destruction!

That's interesting what you say about the pressure pads. I was up too late last night reading about the motors providing inconsistent back pressure to keep the contact with the head, hence the pads. I wondered about reducing wear by removing them, in this age of irreplaceable heads, but didn't know this could be done by using newer tape types. When it's up and running I'll have to experiment!

Meanwhile, two of the motors have been dismantled, cleaned up and lubricated...
