This photograph is reference audio system of Miyajima-Lab.
I explain each product with a photograph.
- - - Speaker & Horne - - -
A woofer is Jensen of 70 years ago.
Jensen is an excitation type.
The tweeter is Electro-Voice.
The driver is top quality goods of WE555.
I produced original wooden Horne for WE555.
This Horne is calculated for WE555 driver minutely.
The metal box is WE555 and a network of the tweeters.
I match the phase of three speakers.
This is a 7V power supply for WE555.
I use selenium for a rectifier.

Model 2010 x 2
The lower power amp drives a woofer.
The upper power amp drives WE555 and a tweeter.

Model Wo-1 (Japanese specifications)
I named this pre-amp "Wo-1".
The meaning of the name is World-1.
The volume mechanism of this Wo-1 is special.
Because a sound does not pass resistance, the sound keeps the best quality.
The circuit of this amplifier is very difficult and resembles OTL circuit.
This amplifier has a power supply of ±.
I want to produce overseas specifications of Wo-1 sometime.
I produce the vacuum tube-type head amplifier other than a stepup transformer.
The vacuum tube-type head amplifier is an ideal amplifier.
However, I must solve the problem of the shield of this head amplifier.
I make an effort to be able to sell this head amplifier to the market.
The following photograph is a reference LP to test a cartridge.
Most LPs are original records.
