Vacuum Audio Labs

There is a pair of mono tube amps on EBAY called "Vacuum Audio Labs" and the descriptions says they are based on the Audio Note Ongaku design. Anybody know anything about these amps?
Doesn't look very Ongaku to me. The driver tube is a 2a3 in the Ongaku. Beware.
The Vacuum Audio Labs amps were imported From China only for a short time by Parts Express due to problems with lead times and parts availability.They are no longer being sold anywhere outside of China.Parts and reliability could possibly be an issue.
Thank you; nice to know these things when reviewing the open auctions.
