Vacuum tube power amplifier LUXKIT A3500 self-bias specification

This is the EL34 push-pull power amplifier made by Lux, which is still popular today.
Comes with a bonnet and a 3P power cable for the PC.

In addition to EL34, this power amplifier includes 6L6GC, British KT66, KT88,
It was sold as an amplifier with specifications that could be replaced with vacuum tubes such as domestically produced 50CA10.
Remodeling is possible with a little modification.
This product has been modified to a self-bias circuit with emphasis on vacuum tube runaway rather than physical characteristics.
Since this is a purchased item, we have confirmed that it does make noise, but it is not covered by the warranty.
Currently, I was able to hear a beautiful and dynamic sound with no noise.

*The price is the cost of modifying it to a self-bias circuit.
It has a 3-connection operation with good sound and the power is around 10W for each channel.
*Vacuum tubes require a strict pair of tubes, so if the bulbs you are using are not a pair, a separate vacuum tube fee will be charged.
*Additionally, restoration of the original circuit and maintenance in the event of a breakdown are possible, although there will be an additional charge. Please contact us.

Self-bias modification 80,000 yen (modification includes replacement and maintenance of old parts such as capacitors)
