A fruitfull evening

[Rob Jarratt]

I have a supply of the new hammer pads in the UK. Their maker sent them to me for distribution in the zUK and Europe. I think it is about $7 for 10 (would need to check, but it is around that price)

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.
