Awhile back a poster started a thread on Walter's amps. We created an interesting discussion of their history and his product development over the years. Specifically people were posting photos and doing comparisons that I found very interesting. The original poster selfishly deleted the entire thread and then went off to ebay to scour up the "desired" models. It is my intention for us to recreate and resume that discussion, which I will leave alone for others to consult. Any interest?
