Where do I find the 2465B restoration pdf? Thanks. Steve

Put a drop of oil on the shaft near where it enters the pot. I use PB Blaster penetrate oil. In 15 minutes, the thing will be like new. Tom

The price difference is because the AT-GPIB/TNT is an antique ISA board that's compatible with fewer PCs and operating systems. $100 would be a good price for an NI PCI-GPIB board. -- john, KE5FX

David would that be a PCI-GPIB IEEE 488.2 183617K-01 Interface Card or a AT-GPIB/TNT IEEE 488.2 card? The former is ~100 USD and the latter ~30 USD. It seems my workstation can handle another card..

Because I needed one of those 1/8" plastic flex joints recently and did not have one, I extended an .050" hex wrench today and changed those couplers on a 465. I replaced the two flex joints with two

But stick with a real LF13333N if you can. The alternative isn't as good for this application (I don't think it turns on as rapidly). Dave

I've also been known to replace the fiberglass with a normal grocery-store style wooden skewer. Then ones I have are exactly the same size. Respectfully, Cliff White, W5CNW

There are two versions of board A29 divided at 7854 serial number B085124 and below but the schematics are basically identical. DG181 is the part number used for a bunch of the analog multiplexors.

I'm thinking of buying the parts to refurb my 2465A, but I wanted to know if the parts documented in the 2465B restoration PDF have a good chance of being the same. The service manual I have does not

Thank you for all the suggestions. I think I will try the tubing. With a bit of luck, might even be able to do it a part gripper and not need tearing down down the scope. Now to find a cover... -d

I'm sure I'm being a dummy, but I suddenly am getting no signal continuity through the spring hook tip when placed on one of my P6133 probes. I'm just about certain I used this same spring clip on

I often use silicon fuel tubings as used for miniature (1:8) petrol racing cars. Make sure the inner diameter is small enough to give a tight fit and use length of 1 - 1.5", so it won't slip. Wall

Hi David, On "my" schematic 34 there is no U1620A or U2 and no D181 or U3. I found the TL 72 OpAmp. I have a U900 aa vertical D/A converter an a U1010 as horizontal D/A converter. Gerhard

Those fragile plastic flex connectors are impossible to find as far as I know, but I question whether a flex coupler is even needed there. The VAR shaft from the knob back to that flex connector is a

I assume that the character display works correctly even when the stored signal has no or a low vertical deflection. I think you will find the problem around U1620A or U2 on schematic 34. If reseating

After a warmup time of approx 2 hours the stored signal is displayed in the stored mode but only with an ampltude of 35% of the applied signal. Gerhard

I find references to 2465s within a range of serial numbers having a "higher than normal" IC failure rate, but have been unable to find which serial numbers. Please point me in the right direction.

I swapped the RAM Board and now the 2nd 7854 has the opt 2D. The 1st 7854 has still the problem, that it doesn't display the stored signal in the store mode, it shows only a horizontal line. Where can
