• Anotaciones
• Westmore 501 Tube Tester. Made Between 1959 and 1967. This Tester was made by the Triplett Company and sold under the Westmore name. The same model from Triplett is a model 3444. This model has a 5kHz oscillator for a signal supply and can also read plate current up to 50ma. The Triplet 3444 and Westmore 501 were listed as a Labortory Grade tube Tester. This tester can use the tube manufactures data sheet to setup a test for a tube not listed in the roll charts.
  
  The only difference between the 501 and the 3444 is an added lamp in series with the AC line, as an overload indicator. This was also incorporated into the 3444A. This Tester was replaced in 1968 with the solid state Triplett 3444A.
  
  The 501 manual is similar to the 3444 manual, but rewritten and rearranged. It reads "anode" instead of "plate". The manual also has a guarantee for government contracts. Alan Douglas is concluding that the 501 was a model made by Triplett to fill a government contract (could have been for the F.A.A.) with a dummy corporation set up for the purpose.
