HiThanks to everyone for their comments and thoughts, very much appreciated.I've found a Tek 2200 series brochure and it lists the following differences: 100MHz bandwidth (2230), 60MHz (2220,2221)4K

I'm sure you can just file a flat even with the shaft installed on the scope. ST <TekScopes@...> wrote:

So it is not a problem with the CRT. When they get old, the trace becomes both dim and less well focused because of lack of emission from the cathode. There is another possibility with the CRT though.

Hello everyone. I was recently given an early 465 scope. It has a trace and seems to work somewhat, but needs some TLC. I'm new to oscilloscopes, so bear with me if I say something wrong. This is an

I'm not sure what the mechanical situation is here, but if setscrew grip is a problem, and the shaft assembly can be taken apart, you may want to grind or machine a flat on the shaft, then use the

That's awesome. I'm assuming the -02 is an updated compatible design so would prefer that version. Ill reply off list with details. Thank you! [TekScopes]" <TekScopes@...> wrote:

Again. I got OCD bad about this. I thought I had a viable glue/threaded insert repair going for my 1A4 var pot, it works well at room temperature but as soon as the scope warms up it loses grip. This

Hi, I have one 155-0049-02 and will check my cabinets tomorrow to see if i have a -01. It would be $15 shiped to lower 48. respond off list to j_massengale@... Jerry Massengale

Hi Mac, Since your response came so quickly, I couldn't resist to answer before going to sleep: Barry describes (part of) his problem as follows: The problem as described by you (Mac) from msgs.

Thanks, I'll have a look tomorrow. It's 03:51 (AM) here... Raymond

My first post and description of the problem is in the archives as message?number 89026, dated Feb 23, 2013.? The thread is 48 messages long and addresses the repair and restoration of my 2465.??

That part is used in several early 7000-series time bases. 7B50A and 7B53A are examples. A while ago, while still available, these plugins could be had for a few $$. IYou may want to check the

Thanks for that info, Mac. I based my response on what I remember of the (all too frequent) messages of vertical compression, from the middle increasing towards the top of the screen, for channels 1

If I follow you correctly the 1,2,5 part gain changes but the decade function provided by changing the current sense resistor doesn't. That is switched by the b section of sw400 which is the wafer

Thanks for the tip on ripple and testing with a voltmeter. I found that as an option after some digging later but didn't know if it would be accurate enough to make diagnosis. The scorching hot IC is

I have a collection of scopes, about 1/2 are Tek. This last weekend was very wet and humid. I fired up one of my 'brand X' (100 MHz) scopes to work on a preamp and was surprised to see the focus was

I own a 2465 which exhibited non-linear vertical traces for Ch1 and Ch 2.? I traced the problem to failed -8 Volts from the LVPS.? In particular, 1101.? I recapped and all was well.? Still using
