The basic architecture of a 30W amplifier based on push pull configured 6550 output pentodes biased into Class A remains unchanged. However, the single power transformer has been replaced by two separate transformers; one for the valve rectified and choke smoothed HT supply, the other for the filaments, “Overall this allows for cooler operation and a lower noise floor,” said the company.

The output transformer design has also been refined with improved lamination material and a different winding arrangement, “…yielding wider bandwidth,” said the company.
