Above is a chassis photo of the newly proposed VTA Lipraloof M-500 500 watt monoblock amp. Someone had suggested to me to create a larger 8 output tube per monoblock but I figured lets just go all the way and make it a 500 watt monoblock amp with SIXTEEN output tubes! Yes - the power transformer uses the same mounting holes as the M-125 monoblock but the stack instead of being 2.75 inches high is now a full 12 inches high. The power transformer will weigh in at a hernia inducing 40 pounds. The quad cap cut out will be retained for looks but the amp will have an under chassis 5000 uF power board. There is only one rectifier tube socket but I will be contacting Weber to make a new WZ68686868 copper cap solid state rectifier with can flow about 1000 milliamps. If these monoblocks are used with some nice efficient Klipsch 100+ dB speakers, you should be able to reach at least 125 dB of loudness in your living room. Your neighbors (up to a block away) may be a little upset but at least you can say you are listening at "concert levels".
This amp is still in the design stage. If any of the forum members have any ideas about what they would like to see in this newly proposed amp they should post their ideas here ..
