45 PP tube amplifier prototype version using Tamura transformer. Due to limitation of transformer, order made for this amplifier will use TANGO or ISO transformer. It can be used as pre or buffer amp.

Driver stage use 396A(5670) tube. OUtput power is 7.5W for 8ohm, it can be changed to 16ohm, 15W

It is now 100V but can be changed to 117, 230V. If you want to change to 117 or 230V, need to wait about 3 weeks.

This is prototype so price is cheaper than order made. If you saw this item is sold out. The same order one will cost 2500USD.

Why do the prototype products are cheaper than order made ?
Because it use vintage transformer, not new transformer.
