Glass Heated Tube & O-Sealing Ring Cylinder Warming Accessory Suitable for Stirling Engine Model

I picked up this stirling engine several years ago. It had been sitting on a shelf about 5' off the ground, I was blowing the dust off my home audio equipment (think loud) the bass from the 15" powered sub caused my stirling engine to do a pirouette off the shelf, breaking the glass heating tube. The replacement part fit perfectly. This stirling engine, though more mechanical than most, is very efficient and runs great. Highly recommended.
