Need to build an amp that'll blow the paint off the walls? Here's the sturdy steel chassis that'll make that happen at an affordable price. Punched for a single rectifier tube, four power tubes and three preamp tubes. Measures 21" long X 2 5/8" deep X 4 1/8" tall. White lettering is pretty nicely done. As on the other chassis we import from China the metal finishing is far from perfect. All of 'em show some fine scratches under the chrome plating.
