Not sure how to search for this so I'll ask: has Duke ever recommended particular amplifiers for particular cabinets? Have members here found particular amplifiers work especially well with particular cabinets?
I don't recall Duke recommending a particular amp with a particular cabinet. I have TC112v4s, and have found the Genzler MG800 to be superb in providing a clean, punchy sound. I've also used the Mesa Subway D800+ which gave an excellent and slightly more colored but great result as well.
And to @Al Kraft, thanks for contacting Duke and letting us know he's facing a big challenge but doing OK.
