Greg, I would be intersted in two sets of gears if available. Let me know. Thanks

Hi, I notice that you have two RF Sections for your 141T and so may be just one IF Section. If so, here's what can happen and has done to me if I've been swapping sections. The D-shell connectors

Hi Richard, It doesn't seem to change with tappings, however the tube has a ringing sound after a tap. It has also little rattle. I'm sure this scope got a big lateral shock at one point in its life,

I have just bought one of these off ebay with the intention of using the main connector for an extender card. The rest is definitely surplus to my requirements. I also have a spare 182C mainframe in

Hi John According to Google there seem to be several sources for 08753-60098. Also might want to contact http://myworld.ebay.com/yixunhk/ - I have managed to get some 8753 parts from them. 73, Jaakko

Hi Group!! I have a 8753C VNA that is missing the power supply assembly A15. The part number is 08753-60098 or 08753-69098. Does anybody have a spare one for sale? I will consider a dead unit. Thanks
