RM100 heat sink bar

[pouet88]

has any of you operate the amp without the heat sink bar ???
Does it do a great job ??

Are you talking about the long aluminum bar that goes across the back? That's not a heat sink, that's just there to protect the tubes. I lost the one on my RM100 a long time ago. As long as you're careful that nothing can come in and smash the tubes, you'll be fine. There are loads of old Marshall heads out there that don't have any rear protection.

Not that I think it does anything other than protect tubes from damage and idiots hands from burns, but technically it is also a heat sink. I think that answers both of you..

In actuality, it's primary function is to satisfy the legal requirements for the manufacturing a tube amp. It's primary role is to help protect from accidental burns and injury. Your amp will run the same with or without it.
