This is a follow-up to an earlier post. I have been given the opportunity to buy an Ampeg solid state fliptop combo from my uncle. He got it as part of a package deal. He plays upright bass in a number of bands, but had never used amplification until recently, when he got a great deal on an Ampeg Baby Bass and two combos, a newer "Rocketbass" 1x15 and the one I'm asking about here. He doesn't really know anything about amplifiers, but he likes the newer one and said he'd sell me the older one for $100. If it's worth much more than that, I don't want to rip him off, so I'd like to get a reasonable idea of what it's worth. Based on what I've read in the forums here and elsewhere on the net, I'm pretty sure it's circa 1967. I'm posting a few pictures here in the hopes that someone may be able to correct me on the age if I'm wrong and give some idea of its value. Thanks in advance for your help.
