I'm building an LA2A, following Dave Jahnsen's "How to Build a Tube Compressor/Limiter" guide. I'm very early into the process but I'd love to hear from others who have done this... OR EVEN ANYONE WHO'S BUILT THEIR OWN GEAR. The LA2A specific question I have is thus: UAudio has reissued the LA2A and has a part called the T4 Cell, which is their new version of the famous T4B. Is this replacement part better or worse than the JBL or ADL versions? The Global question I have is thus: Who can recommend a good place for fabricating a chassis? I'm looking to get a heavy gauge aluminum chassis face, like the DW Fearn Mic Pre. Any ideas?[/b] Otherwise, I welcome any other comments from anyone who's followed this guide and built a LA2A! Thanks!
