Is the original in Denon of TO-3 package?Thanks. Will look for that option if getting original Denon spare is a problem. With these spares the only problem is that we can't fix it to chassis for heat dissipation.
Same regulator could come in different packages.

The TO-220 package ones have a hole through which you could screw a heat sink or screw it directly to the chassis.
Just confirm with the technician what the package is or click a photograph and post it.
