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

Step #1: get the manual downloaded from the BAMA mirror site and check the power supplies.

Hi John, It seems that you mixed up two ICs. At my B058082 PCB, U722 is a round case CA3130, while U842 is a DIL labeled 0067-02 (741 in another unit). Both are correctly marked at the PCB and both

(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

(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

I have no idea Albert. I also do not have so much space. I still have an 2467 and this Iwatsu SS-7635 where it is nearly impossible getting valuable hints for needed adjustments. Matthias Am

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

Is that $40 a buy-it-now price or a starting price? Just curious, fortunately too far away since my attic is overcrowded already. Albert

Put in an offer and got a good looking 7B80 TB from ePay. Seller said untested. Unusually for me it seemed to work fine too, but when doing a CAL check found sweep slightly out and front panel

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

looks very nice. Unfortunately too far away for me living in germany. Matthias Am 15.07.2012 02:18, schrieb sipespresso:

nice, i want have hin. But i am in Germany :-( I has one 531 in grey square corner. Regards Matt

I can fabricate new blue filters for the 2467x series or the 2465x series like Tom Jobe said. Please contact me offline if interested. --Victor

Hi I got this scope used and when i started it i couldnt get a trace, after some fiddling i discovered that the trace was as wide as the screen. There is some reaction from the controls and i can

David, In theory that may be so, but try telling *all* my 7071 and 7081 meters that this is the case - the AC buffer amplifier drifts for a lengthy period after power on. Before the latest change

Every time I read the LM334 data sheet, I wonder the same thing. The 1N457 is not particularly fast or low leakage so I do not know what distinguishes it for this application other than the data

Perhaps better for David, Farnell have them as well. Since they are made by Fairchild, they should be using the correct ex-National process. http://www.findchips.com/avail?part=1n457 I don't know a

David, Mouser has buckets of 1N457's at $0.14 each. Leon Robinson ?? K5JLR Political Correctness is a Political Disease.
