AVT5229 A +

It has been seen for a dozen or so years that tube amplifiers are experiencing a renaissance. Unfortunately, the quality of lamps is different, especially those that have been on shelves for many years. The presented tester will not only allow you to check the lamps, but also is a very interesting combination of microprocessor technology and relatively high voltages.

Basic parameters:

• Measurement of lamps at typical and atypical work points
• Built-in catalog with the data of the 100 most popular lamps
• Possibility to use the meter as independent power supplies (incandescent, anode)
• Measurement of all significant voltages and currents on the electrodes of the measured lamp
• Automatic measurement of basic parameters with the calculation of derived parameters: S [mA / V], K (V / V) voltage gain, internal resistance at the R [kV] operating point
• Presentation of data on the LCD display
• Transmission of measurement results to a PC via the RS232 interface.

The set includes a printed circuit board, programmed layout and documentation.
