9 2. Safety instructions 2.1. Before you begin before using your v 70, please remove the protective grille and install the output tubes supplied with your amplifier in the appropriate sockets (see removing the grille and tube layout). Replace the grille before switching on. Operating the amplifier w...

21 10. Troubleshooting hum and crackling hum in an audio system is often caused by several system components being earthed individu- ally. It is particularly common with tuners, vcrs or satellite receivers where the earthed aerial cables can cause a hum loop via the aerial input. Tube power amplif...

24 13. Frequently asked questions (faq) 1. Can you operate the v70 when no loudspeakers are connected? Yes. The v 70, like all octave amplifiers, is fully protected against open circuit operation, i.E. The amplifier will come to no harm if it is operated without loudspeakers connected. 2. How do you...

25 13. Frequently asked questions (faq) 6. What is the idea of selectable gain? It becomes difficult to adjust the volume when driving loudspeakers with sensitivities greater than 98 db. As the range of adjustment is limited to the lower end of the volume control, it is difficult to adjust the volum...
