Yes, but the size of the caps is somewhat critical because they are also across the primary of the transformer. When everything is right, the contacts last a very long time and reliabilty is good. A huge number of car radios used vibrators. I have a Philco portable radio which uses a two volt lead acid storage battery to light the tube filaments and drive a vibrator supply for the plate voltage. The original vibrator is still good after nearly 75 years and the radio weighs about 25 pounds.
