The new KOOKABURRA SE45
- Seen here with a GE 5751 or 12AY7 input tube with a truly pristine and very natural sound ,again featuring Sowter Nickel Permalloy 80 output transformers with copper wire ,providing a very extended bandwidth and stunning bass !!
- Again the 45 tube " The King of true tone ".
- 10Hz - 80 KHz frequency response .
- Copper foil Jupiter capacitors and all high end resistors and film power supply capacitors .
- Copper and Silver Foil internal wiring .
- We designed this amplifier to be the at the pinnacle of sound reproduction and engineering .
- Tube rectified , all film power supply capacitors , Jupiter coupling capacitors and all high end components .
- It is by far the most revealing and natural sound to date.
- Can be used with a simple passive Volume control from CD or DAC without a pre amplifier .
- Full power at 20Hz flat ,which is amazing bass for a 45 tube ,that other manufacturers really struggle to come close to !! and stretching out beyond 80KHz in the high frequency end in the amplifier, not measured with a 600 ohm load on the bench with no tube in the circuit
*****************
The Natural flow of music in all its forms is so well preserved with Permalloy we can see why AN Japan Ongaku use this material .
The 45 , 2A3 & 300B were designed for audio , the 211 was made for high power transmitters with very high plate resistance making it very hard to wind for decent bass requiring many more turns on the bobbin , potentially creating capacitance and leakage inductance issues that can blur the sound.

We use a 50/50 mix of copper and silver foil wire in our circuits from the input RCA connector to the first and second tube protected in teflon tubing .
The copper wire is coated in pure virgin olive oil to help prevent oxidising .
It makes a big difference in the sound of our amplifiers .
We don't use cheap microphone cable as is the habit of many Manufacturers .
