I have $1k into two loaded 940's. One cost me $250 plus $50 for a better faceplate...and about 8 hours bench time to fix the VCO/PLL circuit boards.
It's back on the bench for a power supply upgrade - new cooling fan and mounts, plus a crowbar circuit for the 28v PA line. Have to repair the attenuator pad and am going to perform the AM mod while the rig is apart. When it's finished I'll do the same to the one which arrived in "working" condition.
