I am servicing a 7A26 and have a question about using DEOXIT D100 on the attenuator sping leaf contacts. In the 7A26 service manual there is a statement as follows: "Do not apply any solvent

Hi Benedikt , I had the same problem for a number of years with the input amp being intermittent , when I finally got time to fix it I could not find a source for the 0216 chip , in desperation I

HI, I'm repairing a sick 7D20 for a friend and I'm almost finished. Sadly one of the unobtanium input Amplifiers (155-0216-00) has gone bad and neither fleabay nor the canadian connection seems to

I'm in the process of troubleshooting a few things in my 7B50 and I notice the schematic shows a connection to the A15 pin of the rear connector and that connection is labeled EXTERNAL SINGLE SWEEP.

Only the 2465B with serial number past 50K should have the A5 SMD board.

I acquired a 5223 in order to test some plug-ins (5A48s and 5B25Ns), and I guess I didn't do enough research before I bought, because I wound up with a 5223 Opt 10 (GPIB) and TekWiki says that there

VR746 is in the power supply to the base of Q754. Mark

Thanks - Cap seems OK, can't find VR 746 (as Tektonix seem to have their own way of assigning groups. Maybe I'd better get better close-up glasses!) So voltages seem normal - and the fuse is OK.

If a scope is going to be new to you get a 465 or 465b so you learn the functions and what they do. Then in a year pick up a modern scope. Just my 2 cents

That’s the solution for a square peg in a round hole.

I noticed the "little wings" on the Berg design and I didn't recall those being on the one I have. That's part of what prompted me to wonder if they were interchangeable. Thanks, Barry(who listened

One more advantage of the Berg design is the silicone plug. It is moisture proof and solder proof. That’s great for washing after soldering and limiting crud after the wire is inserted. Take care to

Sorry for veering off-topic, but I have a room for my hobbies and my other half has a room for hers. The rest of the house is ours. It works delightfully for both of us. My room is also my

Don't forget parts units for things like HV transformers, power supplies, custom ICs CRTs, FP hardware. 7904, 7103, 2430A, and TDS540A on the bench.  2430A is mostly backup, 7103 is just in case. 

scopes take up very little room until......the collection grows past 3 and you get into the big beauties.....unfortunately I agree you do need 2....(especially when they are just two channel os why I

The 2465 doesn't have a battery backup, unlike the 2465A and B. So you don't have to worry about a battery that has failed, or is about to. The two scopes on my bench are the 2465 and a 7904. Tom

Remember, two oscilloscopes is why your car has a spare tire. Harvey

Hello-- A couple of questions: will you need to tote the scope up ladders or many flights of stairs? That argues for lower weight and smaller size. Also, scopes with built-in data capture are

Hi Jeff, et al., Thanks for heads-up - I'll look into it! Kind regards,John
