Does anyone know when JBL first started using particle board construction on its factory cabinets?
Is it possible that some of the longest-running designs, like the C-36, C-38, and C-40 used particle board rather than plywood around 1963-64 or even later?
I found this post but it didn't answer the question, unfortunately: http://www.audioheritage.org/vbullet...Particle-Board
