Early production 47-1227 sets used a bakelite block which contained two capacitors as the AC line bypass. This was changed in Run 3 to two separate mica caps.
The same change was made to model 47-1230.
A plug for Chuck: this is one example of the kind of information you can get in his service packets.

As you have two mica caps as the AC line filter, as stated previously, they should be replaced with two X1/Y2 safety caps.
