Hi Jim, I forgot about Ted Webber previously. If you can't wait for a hamfest go here: https://taweber.powweb.com/weber/ click on Signature Series and then AlNiCo Signature 10. Dig around on that website. It seems to have some audiophoolery perhaps, but that one I found is a lot less than what you seemed to find. I have no idea what a "tweed amp" is. 73 Rob K5UJ
