Actually there are quite a few early molded carbon comps in his chassis. Whether they are original or replacements is a good question.

I believe it also has the diode detector mod for delayed AVC as Morzh mentioned. It separates the two diode plates and uses one for audio detector and the other for delayed AVC, as evidenced by the two 1 Meg resistors and the mica coupling cap.

The detector circuit certainly does not agree with the schematic he is using.
