6N3 Tube Preamp Case

thingiverse

Update 24/1-2016!! New simplified version in two pieces with cut through logo A case for the cheap but wonderful little Chinese Guanzo tube preamp based on 6n3 tubes found here from Sain Smart, also available from several eBay sellers and Amazon. If you need a complete setup I can warmly recommend combining this preamp with a TPA3116 power amp, this will give you a great sounding stereo for under 100$ (not including filament costs ;-)). Matching poweramp case for a TPA3116 or other chipamp found here To build you'll need: Tube preamp kit as mentioned above with transformer M2 16mm screws M3 12mm screws Double sided heat resistant tape for isolation (and for securing the transformer to the bottom of the case) Power cord with power switch or chord and a switch like [this one](http://www.dhgate.com/product/mini-5x-2pin-15a-250v-car-auto-dash-toggle/258786651.html) One double and one single terminal block Tube of super glue Ø12mm rubber feet (optional) Print Settings Printer: Zortrax m200 Rafts: Doesn't Matter Supports: Yes Notes: Best printed in ABS or other more heat resistant material since the transformer and tubes give off a little energy when in use. Post-Printing Assembly instructions Coming soon.. Kick back, enjoy Now when it's done just fire it up and put on some nice music as a reward for a job well done, a little Gerry Mulligan or Nick Drake perhaps? (If this is the first time you turn on your amp let it play for a day or two to give the tubes some "burn-in" time)... While listening why not take the opportunity to get familiar with the wonderful world of tubes and tube-rolling? Matching poweramp case available here
