I have a very nice Heathkit IG - 37 for sale. This unit works fine and comes with a very nice factory manual, plus both factory cables. The very hard to find 300 Ohm twin lead connector that plugs into the front of the unit is included. The 300 Ohm twin lead still has the factory alligator test clip setup, that connects to the tuner's external antenna posts also. Price is 125.00 US dollars, plus all shipping/tax costs to your doorstep. No Paypal. TIA
