Restoring 9A1 plugins: need a foto

Martin Mehlhose All Messages By This Member #78214 开云体育 hello friends, I am restoring a 561A with, a 9A1 plugin. In this 9A1, I am not sure if that is original, so I need please a picture made from another 9A1, upside, back, where is the deflection tubes E55L, there are some power resistors mounted. I want to see them on a picture, and please how many ohms they have, I have no application of this 9A1 greetings from germany Martin - picture: my 9A1 -
Albert #78217 Hi Martin, What a strange type designation, does this plugin have a dedicated purpose? The front looks identical to that of a 3A6. The schematics of the 3A6 might help?

Albert #78219 (continued) Not 3A6 but 3A1. You probably have a 3A1 yourself. The internals (left picture) are exactly those of a 3A1. Obviously the big flat 1.5k resistors (310-596) have been replaced.

Albert #78220 (continued, last time I hope, grrr...) I found the 9A1 now in Stan's book and in the 1964 catalog. Being designed for the 506, the plugin has BW 23 MHz (as opposed to 10 MHz for 3A1). Hence those resistors might have a different value in the 9A1. Albert toggle quoted message Show quoted text (continued) Not 3A6 but 3A1. You probably have a 3A1 yourself.

Martin Mehlhose All Messages By This Member #78223 开云体育 hello Albert, this both resistors are 1,5k so it may be still the same then in the 3A1. I will test what it will do when the washing is finished (a lot of work, the old Tek is extremly dirty..) greetings Martin To: TekScopes@yahoogroupcom From: aodiversen@...
