Japanese HF KL-1 Kohjinsha PA

The KL-1 consists of a sophisticated and sturdy Main Unit and a Desk Top
Controller with five meters (HV, IP, IG, FWD, and REF). The LCD displays
BAND and ANTENNA CHANNEL allowing you continuous monitoring of the amplifiers.
The 7 meter (23′) Remote Control Cable allows for remote installation of the Main Unit, providing you a separation with the heat and noise associated with the Main Unit.
Preset tuning makes it easy to QSY quickly from one band to another. You can preset up to 14 frequencies in ham bands . After you set channels, QSY is so easy and quick. You can move up and down between adjacent bands in less than a second. Maximum waiting time to move from 160m to 10m is 30 seconds. KL-1 should help your operation without stress. You can Preset up to 14 frequencies in Ham bands. Preset tuning provides quick frequency changes. Adjacent band changes are less than a second. Maximum time between 160m to 10m is 30 seconds.

designed the bigger size tank coil for KL-1 which is driven by a servo motor to tune to the proper position. You can QSY very quickly without tuning the amplifier. If KL-1 is connected with the transceiver and the personal computer, QSY will be more easy and quick. Because of the above and the direct heat cathode triode, you will be sure to have more chances get more rare stations. The picture shown below is matrix circuit to change bands.

Kojinsha designed the socket for KL-1. The socket is manufactured in Japan. Plate choke coil consists of two coils, one for higher bands and the other for lower bands

The new design big size tank coil, the vacuum variable capacitor, and 3CX3000A7 promise the very reliable operation.

The 5KW FWD and the 500W REF through line wattmeters show peak envelope power. You can watch both forward and reflect power all the time.

Each band has its own input circuit that employs troidal cores. The exciter power very efficiently drives the KL-1. The picture above shows heater choke coil(filament choke coil).
