1969 SUNN 1000S IN GREAT SHAPE! The catalogs say that the amp was developed in San Francisco with ideas and testing by the Grateful Dead, Jefferson Airplane, Pete Townsend and Jimi Hendrix. How's that? 120 WATTS RMS 4 6550'S in the power section, 2-GZ34's (5AR4's) rectifier tubes, 1-6AN8, 1-12AU7 and 1-7025 (a low-noise 12AX7) no reverb tank and tremolo is not working may just need a foot switch ....this is a 2000s for the most part. all offers excepted within reason I paid $650 for this 2 years ago.
