Hi Lew !
From my modest information basic parameters for 12C42C tube is :
- Filament = 12,6V / 4,9A (+/- 0,4A)
- Pd const. max = 120W ( at Vp=120V & Ip=1A +/- 0,2A )
- Rp min = 65R
- special 9 pin jumbo magnoval ceramic socket .
Yes is look interesting , but basically 12C42C tube consist from about three section similar or smaller of 6C33C tube , arranged in 120 degree schedule and internal electrically connected in parallel .
No practical proof but I believe it is good tube for OTL .
