 Palstar LA-1K RF sensing HF Amplifier
I am moving to apartment living and liquidating all my equipment. This amplifier has served me well delivering 1000 watts PEP over the frequency range 1.8 to 54 MHz. 100VAC to 260VAC input power. Has Auto band switching, Auto SWR/short circuit/Over temp protection and variable speed cooling fans. This Amp is build in Ohio and can be serviced there if you ever need it. Maximum power out is obtained with between 40W-55W input power on all bands. This Amp is in pristine condition and I encourage buyers to view the Palstar website at www.palstar.com to review all specs. Dealers have it listed new for $3,795 and I am asking $2,400 which will include my shipping and insurance anywhere in the continental USA.
Once I receive a money order or bank cashier check and it clears I will ship within 2 days.
My new call is W4LR and it was W1BQ previously
