Question is " Can the D-lab ECB Class A amplifier boards run high power output tubes?" Answer: Yes. My boards are simply the preamp and tremolo circuits, your output tube is your choice. The tube/power and output transformers determine the wattage. This video will demonstrate application of the ECB-AT board and a 6L6GC tube. Bias is set for approx 40ma @ 450vdc plate voltage. A real monster of a class A amplifier. I'm bring back the simple days of kit building. More demos will follow utilizing different output tubes. Most of the components shown in this video can be obtained at amplifiedparts.com. If you want a board, bare or populated, visit my website or e-mail me direct. Thanks, d-labelectronics.com Spread the word, help me to grow the shop.
