Up for sale is this 1967 Harmony 525 tube guitar/bass amp in good working order and condition. Great sounding little tube amp with the original Jensen 15” speaker. This was produced by valco and is the same inside as a Supro thunderbolt except this used a solid state rectifier, otherwise totally the same to my knowledge. It was missing the back panel when I got it so I made a new one (see pics). I installed a jack to go straight to the speaker in the back as well so you can run different heads to the Jensen and use it also as a cab for other amps. Such a great sounding speaker, so it’s nice to have the extra option. Missing side og side handle, how I got it. From 1967 the summer of love. Get the legendary thunderbolt tone at a fraction of the cost. Thanks!
