The team making the Psvanes has broken away from Shuguang. I wonder if some loss of facilities or other factor has reduced Psvane's quality control and Grant Fidelity is itself being flooded with problem tubes. Even so, they should be able to cull out microphonic tubes - a fingernail tap was enough to test my bad lot.
GF allegedly rigorously tests the tube B4 selling them.
