It may. I know there's a small "cage" of tubes in it for the power rectification (there's at least one tube type with a topcap in there). The "cage" is a small vented metal box inside the chassis and I understand any high voltage tubes are placed there for safety. It looks like all power rectification (certainly the high voltage) is done via tubes.

My list of tubes is at home and I'm at work. I'll check tonight and let you know the complete list of what tubes the set uses.



Thanks,
Joe
