I know of the Greenkeys list, I joined them 2 weeks ago. I'm going to
look for a proper hose in a few days.
I remember that I used some years go one of those rubber feet, and it did
work well but then I bought some parts from nc.com (when they did stock
much more than today), and acquired a few original rubber hammer pads.
But all the pads I have have become useless now due to gooeing.
It does not have the LT33 modification, although I have seen one once.
That punchread mechanism had an extra position.
My machine is a more or less 'standard' ASR33.
I was not aware of the possible reproduction of rubber hammer pads, I
certainly would be interested in some.
Ik email, dus ik besta.
