This is an early 50s Premier made Marvel vintage guitar amp combo. In the 3-5W range, similar to the Fender 5C1 Champ. I think these were the budget student line of Premier amps. Plug and play ready! Amp has been completely restored with a few mods. Here’s what was done. All components have been replaced. New cap can, blue Sozo caps and carbon comp resistors. The input jacks were very cheap, so I put in new Switchcrafts in a Fender hi/lo design. The 6 alnico speaker has been reconed. I made a new baltic birch speaker baffle. I also installed a 4 ohm speaker out jack if you want to use external speaker and put a Switchcraft plug on the stock speaker. There was no fuse in this amp, so I put a vintage style one on the front where the power cord originally went and moved the new 3 prong power cord to the back of the chassis. The leather handle has also been replaced. All vintage tube lineup is RCA 6SL7GT, CBS 6V6GT and Sylvania 5Y3GT.

1975 Music Man HD-130. Electric Guitar Amplifier Head. It had been used quite a bit by a previous owner who painted some hardware and Tolex black, red on the handle ends, and blue on the logo and badges. The amp was still in good shape and had the original giant rubber sliders and all 8 corners so I bought it and added it right to my collection in the early 1990′s. There is a modification of two holes drilled into back of the chassis in-between the back plates; we cannot figure out what they were for.
