I have an AL-80B, and have owned in the past a variety of 3-500Z amps from SB-220's to Henry 2K's to Drake L4B's, and one old Swan Mark II, and oh, what was that-?, I thin; /archives//html/Amps/2001-09/msg00484.html (12,416 bytes)

How you do it does not matter. Not so. Air flow is air flow. It takes a much lar; /archives//html/Amps/2001-09/msg00514.html (8,450 bytes)
