I've produced a kit to convert a Tektronix 7T11 Sampling Sweep Unit to a 7T11A (this allows you to use it in a 7854 'scope). I am offering this kit at GBP22.50 (about USD36) plus postage which is GBP 5 to the UK, and GBP10 to the rest of the world. I have PCBs on hand to fulfil 7 orders immediately, and will be ordering more boards RSN. A web page giving full details on the conversion process is at: <http://www.perdrix.co.uk/7T11Conversion/index.htm> Please contact me direct (off list) to order. Cheers Dave Partridge
