To be honest, Conrad Johnson actually did use rubber bands to suspend a nuvister tube board in their Premier series phono pre amp in the 80's. The nuvistors were so prone to vibration and mechanical noise that tapping on the cabinet made one helluva ring throughout the system. I did experiment with different types of rubber/silicone bands as an alternative.
I believe I paid $1200 for that unit back then, and it was of usual CJ design - goldish color faceplate on full 19" cabinet. Imagine my suprise to open the cabinet and find only a transformer and 3" x 5" board suspended by rubber bands!
