Amplifier starting from top to bottom is built with 3031 aluminum and bolted together with stainless steel button heads. The antenna tuner has two used 1000 PF large vacuum variables with Gates roller inductor to match about anything. It uses gear motors with rocker switches located on front panel for easy tuning and digital panel meters for reference. The tuner has plenty of room left for adding options such as antenna bypassing and switching. The tuner also uses 7/16 din connectors. The RF deck has new Jennings vacuum variables 10KV at around 2200PF and a new output final 3CX10,000 B7 with heavy duty Gates roller inductor. These are also driven with gear motors with rocker switches and uses digital panel meters as reference. Also capacitors and roller have been charted with digital panel meters so you are able to pretune to specific values before final tuning. This enables you to achieve proper tuning with proper Q. Also from the front panel of the RF deck you can read bias voltage and filament voltage. Both are adjustable from front panel. Leds are used in meters and indication and Jennings vacuum relays on input and output. Rf deck uses airflow switch to turn on filament voltage and high voltage sensing before transmit will be allowed. Also the RF deck uses 7/16 din connectors on output. In pictures below you will see the input tuner for the tube. It uses two air variable capacitors and small Johnson roller inductor driven by three stepper motors. These motors are controlled by three smooth turning rotary optical couplers located on the front panel and also uses the digital panel meter on front for reference to charted capacitance and inductance values. This allows a 1 to 1 SWR for input to cathode and the option to use different settings for different Q on input. The heavy section being the power supply and fan unit houses the transformer multi tapped and set at 7000 volts at approximately 3 amps and a bank of electrolytic capacitors of 70 MFD making a very nice constant amount of voltage and power for the RF deck. This bank of capacitors is very easily removed with just four fasteners. The fan section makes use of a multi speed fan for different temperature output from the final sampled just above the tube. The cabinet uses air filters in the bottom to keep the unit as clean as possible. Power supply does step its voltage to gently charge the capacitor bank. This amplifier was built with heavy duty components and relays in effort to last a life time without much repair. I am including the 10kw oil filled dummy load and 10kw oil filled military balun (both pictured below), extra replacement capacitors, extra digital meter and few replacement relays. This is just a little information about the amplifier. A personal visit will allow you to explore more and get more answers. Priced at $ 15,000
