Features
The source is carefully designed with 5 filter levels besides large-sized choke and oil cap. The power supply for the Power and Driver stages is separated to provide absolute stability and stillness for the amplifier.
Thivan’s OPT sound transformer is designed to be very large (total weight of 6kg / unit – similar to those in the high-end 300B Amplifier). This is aimed to optimize sound quality of tube 300B as well as to reach its capacity of 7.5w across the 20Hz – 20 kHz frequency range.
The components used are of high quality and have been thoroughly tested and guaranteed from Thivan Labs to ensure stable and reliable operation.

PS AUDIO BHK SIGNATURE 250 STEREO POWER AMPLIFIER
The BHK Signature 250 stereo amplifier, and the BHK Signature 300 Mono Amplifier embody one man’s life’s work and passion in the art of amplification. That these monuments to music can be offered to music lovers for less than £50,000 each is a testament to the years of experience invested in their design; that they are significantly less than £10,000 is a miracle.
