Hi folks, I have two 7A26 - the first is now mostly behaving after washing down the switches in scale readout board. The second is generally behaving oddly. My suspicion is that the selector ring of

Hello out there! New to this group thing. I have a 2246A (not mod) that has a bad K104 relay. 148-0174-00 DS1E-m-DC12V-166 Does anyone have one I could aquire? Dana A (Not Mod)

They are wonderful scopes. Please consider making parts available to others from the ones you intend to scrap.

Welcome Kevin! I too am an EE. I’ve got a few more years in than you, but it’s been fun and interesting. These days I’m working on complex HW in the loop simulation systems used fo HW/SW

Just to be clear, I'm talking about 'X2' or 'X class' 'safety, or suppression' capacitors as outlined in "IEC 60384-14" which subsumes "UL 94 V-0" AFAIK, all those class of capacitors have to satisfy

Paul: good call - I hadn't realised that - thank-you! I looked on Ebay, and the ones there aren't quite what I need. Ed: thanks for the thread sizes - saves me fiddling with the thread gauges! I'm

Maybe the correct answer is that these caps should have not been made or sold or bought or used since the problem was known and understood (probably quite a few years ago). I don't know the real

Richard, have a look at a current RIFA manufactured capacitor of the same type and value as you find in a 20 year old instrument. Does it look like they changed anything? Isn't it odd that they are

Not sure. Was repeating what I read here. Rifa was/is a Swedish company. It sold its capacitor division some years ago. See Wikipedia for the history.? My understanding is that Rifa had? patented

Richard: regarding your statement that "the caps that fail are of a design no longer made", are you sure? The Rifa ones I just bought new look exactly the same as the old ones and another person in

Those 950 uF caps in the 7904 and some other models are very nice high quality (called computer grade in the old days) units that are very easy to rebuild. I use an un-crimp/re-crimp method which I

It seems to me they (the rfi filters) are bi-directional: i.e. to prevent coupling of signals both in and out.??? Now RIFA actually refers to a manufacturer,? not a generic type of capacitor but

Hate to follow up my own reply, but if you make your own, be sure to connect all 3 of the can grounding pins on your PCB. Tek used the can as a jumper. -- Paul Amaranth, GCIH | Manchester MI, USA

Search on ebay for Tektronix capacitor adapter and you'll find a bunch. If you want to bother etching your own, it's easy enough to make up a pattern in your favorite drawing program, put probably

conducted emissions (EMI) that the instrument couples onto the power line. I question this. In audio I find them in preamps and not in power amps. That suggests that their purpose is to keep EMI out,

I mispoke, btw - both of my scopes are 7904s not 7904A's. The sick one is older than the other - it has the fixed power cord, rather than an IEC socket for the power supply. I'm wondering about doing
