Dennis, I saw similar things when I was working on Silicon Valley 700W FM amplifiers. The physical orientation of the ATC caps was critical. We noted that sometimes two or three caps needed to be plac

AGREED, We use Mouser primarily, they have a fulfillment center at Love Field (or is it DFW?)so shipping response is great. Having said that we also us Allied, Newark, and Digikey with similar results

If it’s a three battery pack in our area we go to batteries+ and pick up a three cell portable phone battery. Then solder the leads to existing wires and use double sided sticky tape. Works fine. Rega

I don’t have hard knowledge of that but the big deal about Trinitron wasn't the mask. It was the fact that there was only one electron gun and some pretty intricate electronic stuff done to emulate th

Derek, I have several of those. If you’re in the US it will easily fit in a flat rate envelope. I’m on the road till Sunday so it will go out Monday or Tuesday next week. Regards, Stephen Hanselman Da

I would agree, Spamhaus is a bit of a pain BUT they were also very easy to work with. One of my systems was compromised, and had put over 200,000 emails in my outbound queue. It was very creative to f

Derek, First where are you and then if it’s the US which elastomer do you need. I have a number of ‘pulls’ that are available for $10+shipping. Regards, Stephen Hanselman Datagate Systems, LLC

What he said! I have a HP 8663 whose surge protectors stuck little bits in the big filter caps. Saftey glasses are not just for looks. Regards, Stephen Hanselman Datagate Systems, LLC

Bob, On your generator observation. If this is a modern AC source if it high isn’t more likely to be a field voltage issue? Too fast should change frequency, I think... Regards, Stephen Hanselman Data

Ooops sorry I read pots to mean trim pots. Still if you can replace them they will never be as stable after cleaning as new. Regards, Stephen Hanselman Datagate Systems, LLC

Replace them, they are fairly cheap, easy to change, and not noisy. Besides you could change a 10 turn into a 25 turn and make the adjustments way less twitchy. We have seen a significant improvement

Just to add a bit more paranoia. HP, in their 3000/6x,7x computers, used ECL for the high speed "ROM" memory. They did not use normal ROMs but loaded what they called Writable Control Store (WCS) from

Thank you Dennis Regards, Stephen Hanselman Datagate Systems, LLC

Chuck, Thanks that makes very good sense. Although for us pin spacing is not a big issue. I have several small PCBs that take standard pin spaced modern caps and have either pins, screw terminals, or

Chuck, If you have low ESR, high ripple current and high temp, close to or higher capacitance right at or above working voltage (which is what we do) why is physical size important? steve

Agreed, while it is pricy the SimmCon Labs LCD conversion is great. The only downside is the method of getting the video signals. They take a socket and you push that down onto either of two video shi

Actually my partner used that procedure regularly, I think it’s a bit drastic but he swears by it. Regards, Stephen Hanselman Datagate Systems, LLC

Our favorite way was to use a HP 2100 power supply 5VDC at 50Amps. Finds’um every time Regards, Stephen Hanselman Datagate Systems, LLC

When it comes to safes, like lock pick sets, there is a very real fear that less than honest folks will use the information for less than legal purposes. Now ask me about TE manufactures who keep thei

I would look in the HVPS. This PS is fed 24V only and makes all of its internal use voltages it self. Usual suspects caps and such. Shoot me on you have and I’ll see if I have a spare. If you get it w
