引用给你看看:一些解决86的方法:
I too build an EF86 variant of the 18 watter and I've seen and done a few easy things to reduce microphonics.
1. Enlarge the tube socket hole slightly to mildly separate the socket from the chassis and put a large fiber washer between the tube socket and chassis.
2. Put rubber washers above and below the tube socket mounting screws.
3. Use Micalex tube sockets for the EF86 (they seem to be better at absorbing vibration)
4. Use a hi-fi style dampening ring on the tube, works great. |
