Bobs Devices Sky Cinemag SUT. Very few use transformer coupling as it is expensive and time consuming. On 5 MHz I can easily push it to 30 amps Ic at 18 volts and get almost 300 watts output. Later model Zen have better output transformers and bias the input tube differently. Harmonics were pretty much gone after the third. Technical resource and information on receiving and transmitting antennas, amplifiers, radios, baluns, for 160 meters 80 meters and other low bands. 5:1 Lundahl LL1660 line output transformer amplifies the signal by another 12dB and provides a low 350 Ohm output impedance. What follows is a summary of our white paper with the same title. APPLICATION A Very high performance output transformer for push-pull KT88 or similar valves operating in fixed bias mode. Linked mode gives you only one set of controls which governs both channels. While this difference is detectable with a light meter, it is almost invisible to the naked eye. In my Telefunken ELA M 251 vs ADK Z-Mod 251 Microphone Shootout post, I had a couple of people ask which transformer I had in my ADK Z-Mod 251.
