I have two of those 1:1 RCA mod transformers. I think some of you know the ones I mean. 5500 ohm primary/5500 ohm secondary. Weigh about 30-35 lb. I would guess they are good for 250-300 watts of audio or thereabouts. Don't need 'em. Good overall condition. One recently removed from working transmitter. $50.00 each plus shipping.
