, CA. -- The Eimac division of CPI is now delivering production quantities of the 4CX20,000E Power Tetrode for new FM transmitter construction as well as retrofits of transmitters now using the YC-130.
'The 4CX20,000E incorporates most of the features of our 4CX20,000C and is designed to mechanically fit into the same socket and chimney as the YC-130,' said John Allan, Eimac’s Vice President of Marketing. 'We expect that customers will be pleased with the longer lifetime of this tube and the excellent performance in their transmitters. Replacing the YC-130 in existing equipment will require a replacement of the filament transformer, as this tube operates from 10 volts, and a service bulletin for converting the Continental Electronics 816R is available on their website at www.contelec.com. The tube itself is available either through Continental or through distribution. The YC-130 will also continue to be available, offering a choice of tubes to our customers and supporting fielded transmitters.'
