Up for sale, a 1955 Gibson GA-5 “Les Paul Junior” combo amplifier in excellent condition and in perfect working order. Released as a student amplifier as a pair with the Les Paul Junior guitar, the GA-5 is a unique piece of Gibson’s amp history, with a similar Class A circuit to the concurrently produced tweed Fender Champ. Pushing 5 watts of pure tube goodness, this diminutive combo features an elliptical 5x7” speaker and packs a ton of tone into a small package, delivering warm, tight-yet-full cleans and creamy vintage tube breakup when dialed up.

A true no-frills tone machine, the GA-5 features a two-input, single channel design with a Volume control. The point-to-point circuit has been recapped as needed to ensure optimal functionality, and the Volume pot has been replaced. The original transformers are present, with the output transformer dating to the 24th week of 1955, and the original 5x7” elliptical speaker is also present, with a clean frame, dated to the 4th week of ‘55. The vintage tube complement comprises a Westinghouse 6V6 power tube, RCA 5Y3 rectifier, and RCA 6SJ7 pentode.

The original tolex and grillcloth show only minimal wear, and the enclosure retains the original handle. The graphics on the faceplate are very clean, including the “Les Paul Junior”script text.
