With this being a pretty much vintage equipment forum, being that we use alot of vintage vacuum tubes, Im sure alot of you out there have some vintage testing equipment.
I personally own a Simpson 260 series multimeter, I will post some pics of it once I get outta work and get back home to it. So, what vintage test equipment are you using? Post info and pics |

My dad actually gave me the Simpson multimeter, he purchased it new back in the day
Im excited that I have a real use for it now rather than just letting it sit in my closet collecting dust

Having been in the surplus test equipment business for many years, my shop has dozens of instruments from Agilent (HP), Tektronix, Wavetek, Keithley, General Radio, Krohn Hite, Boonton and others. Many of them are not in catalog anymore, but I still wouldn't call then vintage. At least not yet. However, here are some that I do still use that are pretty vintage.
Tektronix 570 vacuun tube curve tracer. Hickok tube testers, USM-118A cardmatic, 539C, 752A B&K Precision 707 tube tester RCA WV-510A master voltohmyst Eico 555 vom (copy of your 260) Heathkit C-3 capacitor checker Kepco HV power supplies Sensitive Research electrostatic HV meters (analog) Beckman L12 megohmmeter Simpson 1699 milliohmmeter

My dad gave me his old TV repair shop stuff. Stark tube tester (not sure of the model as it's at the other house; a Stark VTVM, and one of those old-as-Moses variacs. Also got an old Stark scope, but it's dead. Something else Stark too, maybe a signal generator, can't remember.
The Stark stuff was like a Canadian HeathKit type company that specialized in supplying schools/colleges (I believe). He got all the kits as part of his TV repairman school curriculum in the late 50's - early 60's and had to assemble them all as part of the courses. I still have his textbooks too. Very cool, but HUGE, like 2 phone books stacked. Bound with bolts and wing-nuts. ![]() ..Todd |

I don't think any of my stuff is newer than 15 years old with the Tek 2232 and the HP8903A dating from about that time frame. I gave away the Simpson 260 and the Eico VTVM I built from a kit in about 1965 because a $4 digital meter just works better. I have about 6 tube regulated power supplies that I use a lot, but about 2 years ago I got a HP 6448B that goes from 0 to 650 volts and 0 to 1.7 amps, forget the bush, this will burn down the house! Wimpy tubes don't stand a chance. Still have an HP200AB oscillator and two 331A distortion analyzers but I don't use them much anymore. In the RF domain I use two HP 8656 signal generators, an 8901A modulation analyzer, an old 141T spectrum analyzer and a 5328A frequency counter. All of this stuff came from Ebay, hamfests, surplus houses, and auctions held during the closing of the electronics plants that formerly occupied space in south Florida.
