I got a chance to get back at this. I kept it in the general tube forum for all to see. This is a very complete/original ST-40. I believe every tube to be, and all of the iron. Enjoy the pics. Now some questions for those who know more than I........ Are the knobs available as a set or does anyone know where I can get used ones? The chassis has corrosion, tarnish and minor rust. Anyone have luck cleaning something like this? It might be one that I just keep the screen on, but I would like to show off those bottles. Face plate also? It seams many resisters are newer. Is it possible they are from the orig build? The selector switch was very hard to get working right. Does anyone else run into this with these switches? I have a Harmen Kardon that took just as long. The Eico really sounded decent but needs caps. Major hum going on.
