Just curious as to the level of potential interest in a pair of retrofit modules to replace the now virtually unobtainable, TEK-specific parts U400 & U800 which often seem to fail in these otherwise superb scopes. I'm not an electronics engineer, but a good friend of mine, himself an electronics design engineer, has many of these scopes, often purchased to cannibalise for spares to rebuild 465/2465s with lower hours. He is in the process of prototyping a pair of retrofit modules for these two chips which can be retrofitted by anyone with a moderate degree of soldering skill. He and two of his colleagues between them have over 30(!) of these instruments all needing these replacement chips, so this project has a fair chance of becoming a reality in the next few months. If the volumes are realistic, a ceramic hybrid-based module will be commisioned, or if lower volumes, a pcb with identical footprint to the existing chip outlines. If there's any interest in this project, let's have your thoughts. Regards, JB
