Nutube pre/main amplifier with Class-D power amp

My previous amplifier was headphone amplifier but it will be very fun to use the incredible Nutube with speaker. This time I made a Pre/Main (power) amplifier by Nutube! Power amp consists of Texas TPA3110, enables 15W x 2. As same as all recent my creation. I have a plan to sell this item at tindie.com. Product URL (As of Oct. 25, waiting tindie admin approval...) is https://www.tindie.com/products/microwavemont/nutube-based-15wx2-amplifier-kit-with-class-d-amp/
