4CX250R Eimac Transmitting Tube Broadcast/Industrial (NOS)

4CX250R Eimac Transmitting Tube, Broadcast / Industrial (NOS)

4CX250R/7580/7580W  Can replace  the 7580 in alsmost all applications since it is electrically identical except for a minute (0.2uuf) increase in output-capacitance limits. It will also replace the 4X250B or 4CX250B in equipment where the range of bias adjustment will tolerate the higer perveance tube and where tuning range can compensate for small differences in input and output capacitance.

The 4CX250R will deliver more output power in most linear amplifiers which presently employ the 4X250B or 4CX250B, and it will operate with maximum rated plate and screen voltages applied in equipment where sjock and/or vibration is experienced.
