This post is OT but possibly of interest to B&K 2012 owners. There's a slew of info on the 2012 in my site here: https://pearl-hifi.com/07_Facility_Tour/T_and_M/T_and_M.html#50 and a lot of info

David, Thanks for your comment! No matter how low I turn down the Intensity you can still see this shadow. (Until both the trace and shadow go undetected.) Barry

Hello N4BUQ, I removed the knob and shaft in order to more easily probe the transistors under the shaft. I can still adjust the focus. Thanks, Barry

Looks like the FOCUS control knob and shaft is missing. That might also contribute to a bit of that as well, correct? Thanks, Barry - N4BUQ

Guys, Thanks for showing consensus on this and the additional information. I feel more confident about my -0367- inventory.

I think the SC504 use a expansion mesh PDA. I that's the case, if you turn the brightness up to high levels you will get that effect. David

Greetings, What would cause this? Thank you! /g/TekScopes/photo/300558/3883505?p=Created%2C%2C%2C20%2C2%2C0%2C0

Benjamin, I made an error in my previous response. The junction between R2176 and R2275 is -5V. Barry

Clark and Tom, I agree with tom on this one. As always if the circuit is not working, then troubleshooting is necessary. These are 1.2Ghz Ft parts and as such have an incredibly low reverse break

I dabble in mmwave and have to deal with tiny diodes with 2 to 4 volt breakdowns. I purposely only use a cheap DVM that has a 2v compliance and 1ma max current in diode/ohm mode. My bench meter would

Szabolcs, agree 100% with merit of fiber - good point. I always keep it on hand. There are also many epoxy fillers in addition to fabric for different applications. Marine supply is where I find

Yes, little stress where I used it and it seems strong enough that I could have used 75% less in hindsight. We will see if this was a good choice for my first experience with the product, if any

Hi, I had very good results using glass fiber reinforcement with epoxy. Usually I only need a few strands of glass or an appropriately sized patch. One has to figure out how the stress forces will go

Hi Clark, You might want to check out the summary that Zen (I believe) added to tekwiki: https://w140.com/tekwiki/wiki/SKA6516 In short: "Replace on sight" doesn't seem to be a good policy. --

What was the prevailing opinion on the correct way to test for leakage (e.g. ICEO)? Ed listed some sound reasoning, but I did not see agreement from other members that testing the reverse polarity,

Unfortunately those fixture will not fit or work with the CT-71 and they sell for big $$. Sam Reaves ARS W3OHM

Mike, If your 464 does not have the DM4X multimeter, I have a cover (200-1412-00) for you. I am looking for a cover that will fit 46X/475 models with the DM4X or a 468. That part number is

Hi,i am interested in one,can you mail me its quadzillatech@... cheers Paul.ps see no way to get your email addy on here!.

I suppose it is good in the region that you glued. The most common cracks in the rear cover are at the four corner screws. I have not had good luck gluing the corners using this plastic epoxy repair.
