[QUOTE="Mars, post: 765621, member: 817"] I checked calculations around the 2A3 OPT. The way to make the 2A3 louder would be to improve the efficiency of the OPT. I usually aim for 5%. By using M6 laminations, I can increase the magnetic properties, and use less copper to get the same result. If I make EI96 (with a 32mm stack) transformers, like in the SE88 above, I can actually get the copper losses lower; down to 3.5%. That would probably make your 2A3 a bit louder. I do not know how much louder an amp with 1.5% less copper losses in the OPT will sound; maybe Ampdog can chip in. [/QUOTE]
