Yep, Broadcom Ltd. continues to shed product lines and employees.? They shed me a couple years ago, but haha, I got a better job immediately, took their severance package, and got 2 months off with

I got all of my Scope-Mobiles from the vacuum tube era and a 203 with the TM500 shelves this way. Given how heavy the 500 series oscilloscopes are, having a Scope-Mobile for each one is well worth it.

Two things: 1: I doubt that most of you ever worked on a 16mm film projector. The TP66 Film Chain Projectors used at TV stations had a small Variac to set the filament voltage on the projector bulbs

Thanks for this, Tom, but I think my 466 (serial #B124248 is a bit later, as the innards don't look much like what is shown. I think I'll have to remove the Trigger generator and Sweep Logic board to

Does anybody have a Tek 7D10 Digital Delay plugin for the 7000 series lab scopes that they want to sell or trade? I've been looking on Ebay for over a year and none have shown up. It is a pretty

At least where I am now near St. Louis, voltage spikes kill incandescent, LED, and CFL bulbs about equally with a half life of about half a year so less expensive incandescent bulbs (or passive

Using a diode in series works well for porch lights which do not need to be as bright anyway. The effect on operating life is much greater than the effect on efficiency and brightness:

The recent series Chance with Hugh Laurie had a Tektronix 465M or 465 variant in the back room of the antique furniture shop for some reason. They were using stories from actual science fiction

With incandescent bulbs you could put a diode in series and it would last almost forever. Efficiency was probably really crappy, but it still gave reasonable (if a bit flickery) light output. I've run

And we have modern replacements for sampler diodes in the form of low voltage low capacitance microwave mixing diodes. Although Avago (old HP and now Broadcom) has discontinued theirs, they are still

The failure mechanism in an incandescent light is mainly related to filament thinning as the tungsten evaporates slowly and is deposited on the inside of the glass bulb. Eventually, the inrush current

About 40 years ago an engineer at Stanford University demonstrated the importance of running florescent light fixtures in a three-phase pattern where the three tubes in a fixture were connected to

Hi, I thought that I recalled some discussion on dismantling these A and B time-base knobs safely, but I can't find it now. My problem is that I have a 466 which looks to be fine so far, except for

On my solder station bench I had a drafting lamp with two 20 w tubes that were a real pita. I really liked the fixture so I replaced the tubes with dual row led strips powered by a adjustable 12v

UK TV: 50Hz half frame, interlaced full frame was 25Hz. Dave

I'm not sensitive to flicker, but the point sources from undiffused LED arrays like our new street lights or security lights really hurts my eyes at night. -Dave To: [email protected] Sent:

I made a fixture years ago for working under the car at night.? Three 150W bulbs in ceramic bases.? Not only could I see everything, but it warmed up the carport in the winter!? ?? CFLs are

Correct. Craig
