WARNING!!!!!!! This amplifier contains lethal voltages when operating. DO NOT operate this amplifier with the covers removed. The power supply circuits in this amplifier produce 3000 VOLTS which is LETHAL!!! CAUTION!!! Never attempt to operate the TITAN II without first connecting a suitable antenna or 50 ohm dummy load of sufficient power rating or SERIOUS DAMAGE MAY RESULT!
Band coverage includes 160, 80, 40, 30, 20, and 17 meters as shipped from the factory. With proof of authorization, 12 and 10 meters may be enabled with optional matching network from TEN-TEC. Primary power of 240 VAC is recommended. Operation on 110 VAC is possible with modification to the line input AC board.

CHAPTER 3 OPERATING HINTS 3.1 INTRODUCTION : The following paragraphs provide additional information for getting the best performance from your TITAN II amplifier. 3.1.1 HIGH POWER TETRODE : The 4CX1600B is very rugged and normally operates with a large margin of safety in the TITAN II . It will deliver outstanding service for many years if not damaged by abuse...especially excessive grid current or blockage of cooling air flow.
3.1.5 OPERATION ON 120 VAC : The C. Locate the (81815) Screen supply TITAN II is normally shipped from TEN- board. There should be two jumper TEC wired for operation on 240 VAC.

CHAPTER 5 CIRCUIT DESCRIPTIONS AND ILLUSTRATIONS 5-1 INTRODUCTION The following sections contain detailed circuit board subassemblies used in the Model 416 Linear Amplifier. Also included are circuit trace drawings and detailed component layout diagrams. These drawings are followed by schematic diagrams for each circuit board subassembly.
INPUT MATCHING BOARD (81811) radio license. Note: Operation on the This board contains the input filter, 10m band will also require additional impedance matching networks , and ALC modifications to the bandswitch circuits. assembly. Please contact the factory for The input filter network (81550) is the instructions or further information.

81809 H.V. POWER SUPPLY BOARD This board contains the high voltage rectifier bridge (D1 – D20),H.V. filters (C1 – C9), and H.V. meter circuits (Voltage and current).
Page 27
81815 SCREEN SUPPLY AND GRID BIAS BOARD This board contains the screen supply ,grid bias supply, and protective circuits for the 4CX1600B. The screen voltage is rectified by diodes D4 – D7 and filtered by C1 – C4. This DC voltage is then regulated by pass elements Q9,Q5,Q6, and Q8.
Page 29
81814 QSK BOARD This board contains the low voltage supply , turn-on relay sequencing circuits , and T/R relay control. The low voltage is rectified by D1 – D4 and filtered by C6. U1 and Q4 provide regulation for all low voltage circuits except the negative 16 VDC supply. After a 3 minute warm-up period determined by RC time constant of R5 and C5 ,Q12 will fire turning on the pass element Q7.
