NOTE: SOLD DEPOSIT TAKEN.

HLA-300V Black: The HLA300 is a 12VDC HF broadband linear amplifier suitable for use in the range from 1.8 to 30 MHz with a maximum output of 300W (Av. power) with a maximum input drive of 15W, it has been designed to be used with transceivers with 10W outputs but can be used equally well with any transceiver capable of producing 1 to 15W output. It uses 4 RF power transistors in two parallel push pull circuits biased in class AB. There are 6-Low Pass Filters with (cut-off) frequencies of 3,4,5,8,15,22 and 31MHz that greatly reduce unwanted harmonic output to acceptable levels that may be selected manually or automatically.
It features a microprocessor that controls all of the functions of the amplifier and its protection circuits. Protection is provided for excessive input power, excessive load VSWR and excessive heat sink temperature. The amplifier may be used either in a mobile / portable or fixed station installation.
NOTE: Amplifier tested in good working condition.
