The AR-2 was replaced by the AR-3 around December of 1956. I was about to order a 2 but then got the Christmas catalog from Heath with the 3 in it. The 3 added an antenna trimmer to the front panel and the case is grey instead of brown. I got it for Christmas of '56 and built it (I was in the 9th grade). I used it a lot for a number of years and still have it. I DXed a lot with it on the many foreign transmitters that operated then and also especially in the 75 meter ham band. Mine did not have wax caps in it, but chunky-looking disc caps that look sort of like ceramics. I am guessing they are ceramic.
