Amp Supply LA 1000 Amplifier. Covers 10m to 160m. A compact 1200 PEP watt linear amplifier. Upgrades added: Larger, quieter cooling fan. 12v regulated power supply added. Terminal strip added to change input voltage to either 120 or 240. Uses four 6LQ6 tubes. Has an ATI-6 input board. These boards are rare and sell for $150 to amp builders. The amp was recently tested and produced full output. This amp travels well. I have used it on many of my DXpeditions.
