Digital Sand Bomb

In keeping with the "Bomb" theme here is something I have been playing with.  It is a Step up device based on the Nelson Pass Zen  I/V converter for a Dac.


Of course I have no use for resistive loads, coupling caps or anything digital so I dressed up the 2SK170 / 2SJ74 combo with a good dose of 80% nickel and feed it with a MC cartridge.


Yes this is a stereo pair with both input and output transformers and it loads the cartridge with around 10 ohms. 



Initial tests are quite promising.
