Can directly replace KT66 onto the amplifier to experience different sound with EL34.

See the internal design and structure of the circuit. This is the workmanship of Thomas.

Japanese Matsushita 100uF/100V capacitors (blue caps) for the cathodes of 6SN7 and EL34 are used in this amp.

The coupling capacitors between 6SN7 and EL34 are red TRW 0.20uF film caps. The performance of TRW is neutral and stable. The caps' long feet is very easy to use to make tube amp.
