In working condition. Requires 455 KHz output from your receiver recently changed most of the signal caps and the power cord. Crystal controlled setting works well on both upper and lower sidebands. Manual tuning seems to work on either upper or lower but may need further adjustment. I used this unit with a line output transformer to get the audio to match an 8 ohm speaker. Unit is nice and clean and has bottom and top covers. Place a Bid!
