Organ grade production tubes from early 1960's
Vacuum tube designs historically moved toward more tonal neutrality and physical stability/reliability, rather than toward musical sonic goals.
ECC83-12AX7 factory selected ultra low - no noise, non-microphonics tubes
Vibration sensitivity was a big topic, and any easily-incorporated reduction was sought.
However the reduction of potential microphony also meant reduction of dynamic liveliness with some tubes from that time .
