4CS6 Pentagrid RF Amplifier Miniature All Glass Vintage Philco Electronic Vacuum Tube

This is a genuine, vintage Philco 4CS6 Electronic Tube in it's original box. A collector's special vacuum tube. This tube was developed for gated amplifier in early television receivers. Naturally a vacuum tube with a heater-cathode and five grids can be used for many other special purpose circuits like oscillators and RF amplifiers. Excellent for those antique radio restoration projects or to set up a private vacuum tube museum. It is new, unused, boxed, and kept for all these years in mint condition. First come first serve, as only one of this rare historical vacuum tube available!
