The Power Transistors are TO-220 Package, (silicon case). Prefer TO-3 for heat dissipation. Guess TO-220 are cheaper to make. I can not tell the quality by looking at the EI cow, lol...It is not big and shielding is so so. Only one cow (transformer)? why not 2, 3, or 4,hehe. Good to have two seperate transformer for power amp section and one for pre-amp section, and tiny caps too. Still this could be well build, but not for 10K USD..no way. Very likely this don't cost 10% of MSRP to build and I refuse to pay 90% for design and other things. I have never used integrated amps for nearly 30 years myself, so I can not tell 幾錢有性趣 lol... |
