We prepare for the manufacture of the OTL power amp.
Because we do not yet decide the release time and a price, we cannot answer a question.
Please do not ask us a question.
We are going to change several places parts of the product to a better parts.
The following photographs are processes of the trial product.

　

Wiring : handmade

I do not use a printed wiring board.

(The prediction data of the amplifier)
The frequency of this amplifier is very wide.
10Hz - 100,000Hz (-1dB, 1W,non-NFB)
10Hz - 250,000Hz (-3dB, 1W,non-NFB)
The S/N ratio of this amplifier is very high.

-Out-put-
non-NFB:Stereo 8ohm(about 7W+7W) , Monaural 8ohm(about 16W)
　　　NFB:Stereo 8ohm(about 9W+9W) , Monaural 8ohm(about 22W) 4ohm(about 18W)
(I plan the changeover switch of a stereo amplifier and a monaural amplifier.)

Weight:about 18.5kg
Size:about W450 x H220 x D340 mm
The sound quality of this amplifier clear and powerful.
This amplifier does play music obediently.
This amplifier is long life.
