Re: Dumont knock off of Tek
Greetings,toggle quoted messageShow quoted text
I’m not sure it is fair to call a Dumont scope a Tek knock-off.
Allen B. Dumont opened his company in the 1930’s and was producing an oscilloscope around 1943.
Tektronix was founded in 1946.
HP, founded in 1939 produced its first scope, the HP-130A, on or about 1956.
Initially Dumont was probably the leader in oscilloscope technology for a few years, but Tektronix quickly took the lead.
The competition between Tek and HP was good for the industry in general and Tek and HP specifically. Dumont was unable to keep pace. Perhaps because Mr. Dumont was not as open to new ideas as was Tektronix and Hewlett Packard leaders.
I believe Dumont was eventually acquired by Fairchild. I actually owned a dual beam, four channel Fairchild/Dumont scope. I also owned a number of other Dumont scopes. They really weren’t knock-offs.
Interestingly, a company named Lavoie made “exact” (well sort-of) Tek knock-offs of the 53x and maybe the 54x scopes. The story I heard told that this opportunity came about because the military was pressured to open bid for scopes meeting the Tektronix specifications. I have used some Lavoie scopes a long time ago. From the outside they looked almost exactly like the Tek scope they copied, but the knobs were different. However, they were not the same level of quality construction on the inside as the Tek scopes.
That’s my two cents, FWIW.
