Need Help With Ming Da 300 4T Integrated Amp Tubes

I purchased a MingDa 300B 4T integrated amp that is brand new in the box but has no tubes or user manual. I have searched the internet and can't find any information about this 300B 4T model. I contacted Meixing MingDa and sent them pictures of the 300B 4T and there reply was that they have no record of producing this amp, that that it could be a copy. MingDa also said that this amp looks just like there MC300-A and MC300-AA but they are not sure. Can anyone please tell me what tubes are used in the 300B 4T MingDa integrated amp. I can't order any tubes until I know which one's to get and I want to hear this thing. Any help would be great.
