1970-ish Rickenbacker TR35B bass combo in good shape for a 45-year-old amp: Here's the description from the RIckenbacker Solid State Amplifier Series catalog: "MODEL TR-35B...The Model TR-35B is a low-priced, highly portable amplifier, specifically designed to complement a varied range of instruments. The TR-35B combines all the features found on other TR series amplifiers, such as pre-amp in/out, external speaker jack, and a single 15" speaker specially designed for maximum projection built into a surprisingly versatile unit weighing only 35 pounds. Reasonably priced, this conservatively rated 35 watt amplifier is perfect for practicing, recording and performing small club engagements. Its wide range of tonal response makes it the ideal companion for the multi-instrumentalist." I bought this amp around 1995 and have owned it sfor the past 27 years.
