@moose89 -- I would contact Dennis directly with your issue. You can contact Mr. Had at w4usr@att.net or radiom_dr2856nho@members.ebay.com. I have a Dennis Had Inspire 45 Amp and LP3.1 Preamp, and Mr. Had has answered numerous questions for me, usually responding within 24 to 48 hours. He is a very nice guy and is responsive to fans of his gear. My gear was made in 2018 (he signs and dates each piece of gear on the bottom with usually a gold or silver sharpie. I live in Winston-Salem, NC, which is about 80 miles from where Mr. Had lives.
A friend of mine has one of Mr. Had's 300B amps paired with a pair of Klipsch Cornwalls. One of the sweetest sounding combinations I've ever heard. I am looking at adding one to my collection, but my next purchase is going to be a tube Phono Preamp that Mr. Had builds every now and then. I have Klipsch Forte's matched with my Inspire 45 (that's another story -- like an idiot I had the 45 hooked up to Polk Audio Monitor 10's before I moved my Forte's; 2 watts a channel into 89 efficiency speakers was NOT SMART!).
