SONAR Linear Amplifier BR-21 10 & 11 meter band-Powered with 120VAC
The linear amp is in good condition (see pictures) and good working condition as well!! Had to replace a 12AT7 and a power tube 6JU6!!! Cleaned up control and buffed the power tube pins and cleaned all of the power tube socket pins, generally cleaned the complete unit OK!!!! The Tuning Meter works OK and the Power Light is working, also the selector KNOB is in a sandwich bag to prevent damage!!!!
This Amp is putting out approx. 110 and is rated for approx. 80 to 100 watts on standard 4 watts input and comes with the free Sonar owners manual with power supply schematic and Amp schematic!!
The input wattage is from 1 to 10 watts maximum!!! The owners manual comes with good information which is necessary for tuning the AMP depending on the antenna arrangement which should be done!!! The Sonar amp comes with 4 power tubes 6JU6's which are different tubes than the schematic calls for which are 6JB6's!!!Sometimes this is done to to replace the original tubes with cheaper replacement tubes because usually these power tubes are somewhat expensive!!!! So if the original tubes were installed it might have a bearing on the Amp output as well as re. Tuning the amp which is explained in the manual!!!! Re-tuning the amp itself is easy to do and these controls are easy to get to from outside the case in the rear!!! (see pictures) This AMP is powered by 110 VAC only!! The amp is heavy and will be packed well!! The item "SONAR Linear Amplifier BR-21 10 & 11 meter band-Powered with 120VAC" is in sale since Sunday, July 8, 2018.
