I picked up a Hallicrafters Loudenboomer at Dayton and will restore it when I find time. I remember the ads in QST when I was young. They ads made them look much larger than they are. OK, I know it is just a half-gallon but it is a neat amplifier. This is a HT-45 not the later MkII version. Like to see 866's glowing again. 73 Bill wa4lav
