MODERN SWITCH The modern switch applies a varying level of compression to the preamp section of the amplifier The more drive that is added to the signal the greater the level of compression applied to the signal This has the effect of smoothing out the signal response of the amplifier making the highs and lows more even this also gives the impression of increased sustain For modern lead and rock tones a high drive setting with the modern switch selected produces everything from a liquid solo tone to a chuncky rhythm sound ms the pine switch is applied to a clean setting it also applies a degree of compression but the effect is much more subtle POWER SOCKET POWER FUSE HOLDER For connecting amplifier to mains power supply The fuse protects the AC power of the overall amplifier Use ONLY the correct size and rating of fuse as specified on the panel If a fuse blows or fails and a replacement of the same size and rating is installed and this in turn blows the amplifier has suffered an internal malfunction At this point immediate service from a qualified technician is required DO NOT TRY USING A FUSE OF HIGHER RATING 18 HT FUSE This fuse protects the DC power within the amplifier Use only the correct size rating fuse as specified on the panel If a fuse blows or fails and a replacement of the same size and rating is installed and it in turn blows the amplifier has suffered a malfunction at this point check the output valves and re
