70 watt class a push pull mono block with 2 x GU50
Prometheus – a new audio star by AudioValve – is ready. Prometheus is the successor of Avalon, which we have produced over 20 years. Prometheus has technical features that are currently standard in AudioValve amplifiers. For example, each of the two russian GU50 power tubes is equipped with fully automated bias regulators per channel and is technically of a quality that is unique to the market. The tubes operate in the optimum operating bias current point under all conditions. In the next few days, the technical description follows, now we take photos and vote for the new product on the best sound. Prometheus is available from February 2017.
No sooner said than done, when looking for an alternative, we came across the GU50. Already after the first drafts of a circuit, one channel offered me almost 100 watts stable for a long time – it was clear to me that this was the only way to make an alternative to the 6C33. Months of “loneliness” passed with the development and unbundling of an appropriate circuit board and the appropriate housing when the first pair of trials finally ran in 2018. After a short time, this test developed so confidently in all areas that we all quickly realized – the new power amplifier has been found. Months later we implemented the work in PROMETHEUS as well as in ASSISTENT 100 – Mark 2. In the meantime 2 years have passed and many devices of the new models delight the users. To date, we have not regretted the changeover step and have expanded our portfolio with two further successful products.
