For sale: A very nice original Alpha 70V amplifier. This was ETO/Alpha's original amplifier and was meant to match the Signal/One CX7 transceiver, but will work with any 100 watt exciter. This amp runs a single 3CV1500A7 vapor phase cooled tube. It is in very good condition and runs full output on all bands. $1750.00 - Prefer pickup near Detroit, Michigan, but will ship at your expense.
