Ben,

Misschien kom je hier verder mee.
Mazda 30F27 RF tetrode for TV tuners.
Zie ook Wireless World Jan 1961 pag 75 de 30F27
Geheel uitgelegd en ook die S.

Zie ook JULI-1961 pag 366

From the 1960/61 R & T servicing book: Developments in Television Receivers, page 23.

A new frame grid triode (PC97)
The presence of this beam shield provides a new way of neutralising the valve which has the advantage that one side of the neutralising capacitor can be connected to chassis, the other side going to the beam plate: see Fig 3. This technique is used in some recent tuners.

Met name dus bedoeld voor VHF en UHF TV Tuner ontwerpen.
Zie bv ook TV schema Burggraf F543 Ch= 550F
