Yes, the measurements ware taken with both the coarse and fine "time position" controls fully clockwise, but that gives me something extra to check on tomorrow. Regards, David Partridge

Got a temperature controlled desoldering station with an air pump? Mark

Unknown, untested, looks to be complete but clearly needs attention. Known issues: INST ID button is sticky Missing a side cover CHANNEL B BNC out of round, but looks reshapeable. ARM SMB is damaged

Unknown, untested, looks to be in decent shape. High Res pics at http://www.ozindfw.net/sell/PattGen $50 or best offer +$15 shipping in US. International shipping is available, but you'll coverall

Aaron; I believe you may be looking at a "W" with the front-end mod kit installed. I have several "W"s and an NIB mod kit. Will have to go diggin' though... Bernd Schroder

Hi there, I'm looking for a creative engineer/writer/community leader with some hands-on 'scope experience to run an online community focused on the use and application of that most critical of

Friend worked on the F16, Fly-By-Wire control system and computer. It is an Analog Computer. Turns out, digits were simply not fast enough and powerful (number crunching) enough to deal with the real

Oh my, I see another long discussion starting :). I think that when a high ESR is seen, most of the time, the capacitance falls. At least that is my observation. But also, the power dissipated is

In the Navy in '65 I was treated to a visit inside an F4 Phantom simulator trailor. That was one big analog electromechanical maise on wheels. Analog computers laid the ground work for digital to take

Hello Tom, You are right, high ESR will have high ripple. But heat on cap = (V ripple rms)* (V ripple rms) / ESR (V ripple rms) depends on the capacitance. Higher capacitance --> less ripple Without

Hello Tan, You say: "The filtering caps are also warm (quite hot) which means that it is filtering the ripple and converting to heat. It's not an indication of good ESR though but poor ESR will have

Hi David, The start and stop levels should differ about 5 V. With start I (and you also I think) actually mean the stop level when the trace is at the left position. On the test scope you look at

Thanks Tom, I will download it. You are right, the Q9070 is on the heatsink. I was referring to the U930 driving via Q908 (and CR908) to reach Q9070. Noted on the connection to be broken for direct

I wish I can use this approach but unfortunately it cannot be used in this case because place that are heating up ought to heat up but it may be heating up slightly more than usual. This approach is

Ed, Thank you for your extensive reply. 2220 is a storage 60mHz 2235 is a 100Mhz Non-storage The power supply of the 2220 is quite similar to the 2235 which I can see from the layout. These are some

Qservice is another good source, their pricing is less than Sphere and order fulfillment is very fast. <http://www.qservice.tv/vpasp/shopcontent.asp?type=2445> Patrick Wong AK6C

A weak CRT can cause this also. ________________________________ To: TekScopes@... Sent: Saturday, January 21, 2012 6:14 PM Subject: [TekScopes] focus/astig off the center. ? Hi, I have

They come up on fleabay for 4/$15 every so often. There's always Sphere, if you want to pay $15/each! If I could get that much I'd be buying up 2445s on ebay just for the knob caps. --Victor

I've become a firm believer in the freeze mist. It really helped me recently find a problem transistor in a 7A13 plugin I have. Oh, and a relatively cheap IR thermometer with a laser dot pointer that
