That's great! I was really expecting you to come back and say "I put in the new processor and it doesn't work". This is the first uP failure that I have heard of in a 2465x scope. --Victor

OK, I ended up buying the panel Dan mentioned below as I could never get the screen settings to hold properly on that other panel someone recommended. I just got new panel today, and it is a 16:9

Good idea.... I was able to get all the knobs off of the unit. The plastic ring was a bit tight. I driped a drop of 3/1 oil onto the concentric part of the shaft and we'll see what it does. Thanks

I picked up an oiler from a local hobby shop and filled it with the spray contact cleaner and lubricant that I have. The thin needle makes it easy to reach in and apply the oil to specific spots

T, As far as oil, thats watt I did last night. The Break Free is a good idea. The other possibility is drilling out the allen screws and replacing the knob. The scope is not earning its keep. And i've

I will be there Thursday afternoon, Friday and Saturday until early afternoon. (Feb. 7, 8 and 9) Look for my four tables in the swap building next to restrooms. My equipment is guaranteed to work. I

Thanks Pete, This downloading method worked perfectly. You even have pictures of the later A1007 version! tom jobe...

Some people have had problems getting my pictures so I have put them up on the net for a while. https://home.comcast.net/~preilley_454/2368/7349/Adapter_FET_013-0099-02a.JPG

Maybe you can still run it down the center of the knob? I use PB Blaster penetrating oil with good results. Or a good gun oil like Break-free CLP? Regards, Tom

Thanks for the inputs..... Now I can't get the plastic knobs off. The 'red' one came off ok; on the 'gray', I can't get the allen wrench into the set screw. This is going to be a fun project. klc

Howdy folks, ? Pardon the cross-posting, but I figure this question is of interest to both subsets. ? This weekend, there is a ham fest in Richmond, called Frostfest, which is supposedly one of the

Both the full wave bridge and the large capacitor on the bridge output are very common failures in 4xx scopes such as your 465B. If you replace the bridge, consider putting in the highest spec bridge

I'm getting +.79V on the +5V section of my 465B. I only see .7V out of the rectifier, but about 9VAC in (don't know how I see less out of the bridge than on +5V test). Cap on output of bridge looks

Tom, Thank you, The documentation I sent you is wrong. I confuse easily. Jerry Massengale

I have taken some high resolution pictures of the insides of the FET adapter and two different generations of the transistor/FET adapters. I can send them to you if you would like. They cannot be

Very interesting. The 6802 is a MCU with 128 bytes RAM. 6808 is the same without RAM. It seems that (fortunately for you) your 2464 doesn't use the internal RAM portion. In early days, the MC6802 with

Hi Jerry, Thank you for the documentation on your TO-3 and TO-5 adapters, it arrived in yesterday's mail. I will scan it and get it back to you in a readable form as a PDF file. I can take a

Hi, I need documentation on tek's fet adapter for curve tracers. Jerry Massengale

Wow Albert, your description is very precise and exactly what I already know. My compliments to you! I had described the situation in a very simplified manner to avoid getting Stan into confusion...

I wouldn't call it dirty. What you see is merely the effect of the 1 kHz TD current variation (from Q556/Q566) while both TDs are stable in their high state. It just happened that CR566 shows a larger
