Sphinx Project Eighteen
- Special toroidal transformer (one for each channel!) of 650 VA has the size of a 1000 VA model: safely over-specified.
- Generous energy reserve of 66,000 µF per channel (formed by 30 capacitors in parallel), unlimited power is available for the largest signal peaks.
- Three completely separate power supplies for the input section, driver section and the logic and indicator section.
- Equivalent input noise value of <1 µV (<-120 dBV): remarkable for a pre-amp, but really astounding for a big power amp with two transformers!
