Up for sale here is a vintage 1974 Ampeg V4B head, just serviced (cleaned, biased and resoldered throughout) and running great. Scopes out at over 100 watts before breakup, sounds fantastic for guitar or bass. Typical cosmetic wear, nothing major, ready for another 43 years of rock. Missing the top metal chassis cover, obviously not an issue when the chassis is mounted in the cabinet. One of the all-time classic bass amps, the sound and vibe of an SVT with less power and weight. Only about 55 pounds compared to over 80. $895 shipped.
