TomicTime Posted February 11, 2022 Share Posted February 11, 2022 This is probably ancient history but for those of us children of the 70’s, etc might remember the VPI Magic Brick. The brick did work magic on transformers of even well designed gear. We demonstrated it on CJ Premier amplifiers…most people bought one… Expect tighter bass and a better defined more stable image on transients. There is science involved as it improves the core size of the transformer at relatively low cost. As all tubes are microphonic to some degree it may also improve damping. The core improvement does not apply to Torrids. I have not tried it on Vandy amplifiers, probably not advised due to the combination of over engineered and exotic transformers and built in HRS isolation. These can be found used now and then in the $20 - $30 range…. Link to comment Share on other sites More sharing options...
