Octave V70 CLASS A

Integrert rørforsterker i fra den tyske rørspesialisten Octave (1968). Kort fortalt en forsterker med tonaliteten en forbinder med klasse A, men med fleksibiliteten, kraften og kontrollen en A/B forsterker gir.

Best of both worlds?

"The V70 Class A is not inexpensive but neither is it Octave’s most ambitious integrated offering; that honour goes to the rather similar looking V80SE with its 150 Watts per channel when using KT150 output valves.

The V70 Class A can be used with a few different types of output valve but is supplied with chunky KT120 pentodes in a push-pull arrangement that’s specified to deliver 50 Watts a side with a peak output of 70W (when using the optional external power supply) and importantly as the name suggests these are Class A Watts or so it says.

Octave’s Andreas Hoffman developed what he calls Dynamic Bias Control which he describes as a means of providing “Class-A virtues over the entire frequency response up to maximum modulation”. To the non-engineering eye this looks a bit like the way that a vinyl master can be made with a certain dynamic range, but by gain riding you can increase or decrease its sensitivity according to available power.

Essentially Octave have found a way of moving the Class A power band to suit the signal: cunning stuff!" - Utdrag i fra test hos Hi-Fi+

"In developing the Octave V 70 Class A, Hofmann had the goal of merging Class A sound with the performance of an AB circuit. After this performance, it is beyond any form of doubt that he has achieved his objective. He and his new amp easily managed the balancing act between a sovereign sonic performance and having sufficient power for almost all applications." - utdrag i fra test hos Stereo magazine
