The number one reason that vintage (mobile) tube equipment fails is the radio vibrator in the circuitry to generate high
voltages needed for tubes to operate from low (DC) battery voltages.
Radio vibrators are mechanical devices that were used in mobile tube equipment from the early 1930s up to about 1965.
The mechanical contacts make them prone to failure due to aging with the newest vibrators being more than 50 years
old! This happens regardless whether they were used or just stored (yes, the new-old-stock units fail as well).
|RVB-2 Solid-State Radio Vibrator Overview
PeKo’s RVB-2 Solid State Radio Vibrator provides the vibrator functionality in the form of a small electronics board that
fits in existing vibrator housings.
Several versions are available to cover practically every type of vibrator and tube equipment.
This is what needs to be done:
recommendations on how to do that properly.
Keep the base that holds the pins (the part that plugs into the socket in the equipment) and keep the housing.
determining which connections to make.
Examples of equipment in which radio vibrators were used:
Military radio equipment:
used there are several versions and options possible.
In the list below you can determine the proper part number for the RVB-2:
the primary winding of the transformer to which the vibrator is connected. If this is a positive terminal then it is negative
ground and add the letter “A” to the part number (RVB-2A). If this is a negative terminal then it is positive ground and add
“B” for positive ground (RVB-2B).
not have an enable input, since a vibrator with enable input would not operate when this input is not activated. Certain
military radios have this enabling topology.
