我很郁闷，为什么胆机这么重！！！

这样的用差料,厂家赚大了.还DIY好.

胆机其实就那3头牛重!  管子很轻的

秤不准,四头牛加起来最多三十斤.连管子,机壳等零件总共四十斤左右.

刚放体重秤上。。42KG。。。

There are good reasons for a heavy 300B tube amp.

Output Transformer - the primary inductance should be large so that it would have good low frequency response. Higher inductance requires bigger the core.

Power Transformer - the single ended amplifier runs in Class A at 100% duty. Therefore, bigger transformer will not generate too much heat.

Filtering choke - the amp employs choke filter sounds better. Larger the choke, the better ripple rejection it would have. I use double PI - CLCLC filtering for the B+ to minimize the hum noise from the B+.

If I would buy a tube amp, surely I would believe heavier the better.
