Description

ETO Alpha 87A  Autotune HF Amplifier 1500 Watt Continuous 160-10 Meters (*Some Frequencies Restricted - See Notes).
For shipping information please scroll to the end of this listing.
Guaranteed 100% Working If Picked Up.
No Warranty if shipped. Partial disassembly and buyer reassembly is required if the amplifier is shipped.  Transformer and tubes must be removed and shipped separately when the amplifier is shipped.
The Alpha 87A is capable of 1.5kW continuous RF output on all commonly used modes and on any authorized amateur frequency from 1.8 to 29.7 MHz. Band change and tune-up are microprocessor controlled.
Capable of full CW break-in (QSK) and all digital modes when used with any appropriate transceiver.
Transmit signal path: Drive from the transceiver, applied at the TX RF INPUT connector, passes sequentially through the input wattmeter, tube deck T/R section, input T/R PCB, input matching network, (pair of) 3CX800A7 triode tubes, plate tuning network, output pin diode PCB, output T/R PCB, and output wattmeter PCB to the tx rf out/rx rf in jack.
Receive signal path: TX RF out/RX RF in jack, output wattmeter, output T/R PCB, input T/R PCB, input T/R PCB, tube deck T/R section, and input wattmeter to the TX RF input jack (which is, of course, also the RX signal output to the transceiver). RS-232 communications port: This 25 pin connector and wiring to it is located at the lower left corner of the block diagram.
FCC rules do not permit new amateur amplifiers to be operable on 24-30 MHz as delivered within the US and possessions. Owners who send Alpha Technical Support a photocopy of their authorizing amateur license will promptly be provided information on “unlocking” 12 and 10 meter coverage.
Band Change & Tuning: Automatic under microprocessor control; average time required for complete band change and tune-up, <1 second. No special cables or connections required.
Frequency Coverage: All amateur bands 1.8-29.7 MHz* plus most non-amateur frequencies 6.0-19.0 MHz and 20-30 MHz.
Alpha 87A Specifications
