Okay following the video of w2aew (https://www.youtube.com/watch?v=54roz8IUoVI), I'm now a bit more confident I'm not goofing something up. Pulling the SEC/DIV knob doesn't result in an intensified

Hey All, I've managed to find some time to play with my 2467B and have been trying to untangle whether the non-working CTT option (CT TEST 86 FAIL 02) has broken the B sweep or if the B sweep itself

Thank you!! I just bought the user manual, so I'll be scanning it when it arrives. There is a paper copy of the service manual on eBay for $35 which I will buy if the seller will verify it is the

Seem to be a hard one to find. I scanned mine and you can find it here for some time: www.hakanh.com/dl/temp/11801_Service.pdf It is OCR'ed and bookmarked. Feel free to upload it to TekWiki. /H?kan

Thanks for the replies. I tested the batteries and found that the memory board one was reading almost 0V! Have just replaced, but unfortunately to no avail - still same error. Whilst doing this I also

The fast storage mode had almost no contrast, even straight from the factory. It is normal for them to sport a comfortably bright background, with a ever so slightly brighter trace. The difference

from Tim P (UK) I have three 5000-series storage 'scopes where the store mode seems weak and lacking 'bite' . I have done the 'fade positive' thing as recommended in the manual, to clean out the dead

Also, forgot to mention that there are testpoints and status LEDs on the display and digitizer IO board that can help to narrow down what may be the issue on either of these boards. Table 3-7 and 3-8

Pretty amazing machine for it's time. Been toying around with the idea of getting a Rigol for every day use, but I've not been able to bring myself to the point of dissing my DSA :) The service manual

Have you checked the memory backup batteries?

A big thanks, that certainly answers the loops in the transistor trace in which there is nothing actually wrong with the instrument or transistor Now that just leaves me with the spiking interference

Hi everyone, I've just added a DSA602 (with 32, 33 and 72 plugins) to my Tektronix collection - even though it's a different era the engineering that has gone into these machines seems a great tribute

Hi Reed, I received the NTE539 a few days ago and pulled out the existing HV trippler these evening. It is going to be a tight fit but it looks I can squeeze the new trippler in it’s place. The

The looping you are showing on the pictures with transistor curves are normal for all 577 and all other analog curve tracers. They increase as you decrease drive and increase vert sensitivity. Here is

Cheap hacksaw blades are hardened steel, through-and-through... and break easily. More expensive hacksaw blades are bi-metal, and as such have hardened teeth, and a less hard, more flexible back.

From my experience with hacksaw blades, I think that any attempt at bending them will result in breakage. Then again, if the metal was annealed before bending..., but wouldn't that defeat the object?

Inspired by watch repair methods: A couple pieces of hacksaw blade, de-toothed and shaped on a grinding wheel, then bent into short armed L shape, could make a fine pair of levers to get the knobs

Hi Reginald and others, I looked at ended eBay Auctions and assume the 11801 you bought is the one which auction ended on March the 7th. As far as I know all 11801 and 11802 (the Monochrooms) Models

I have a TM504 where contact B22 on the high-power compartment connector has got mangled. It can be seen that it is sitting badly and maybe shorting to A22. I know that this connector isn't used very
