And if anyone is wondering why build the DYnamite/Dynapsu when I'm more than content with my ZDSE. Three reasons.


(1) I have to orthodynamic headphones that do not share the HD800's love for the ZDSE.
(2) It resembles the KGSSHV "much" from my n00b-ish POV. Both the case/cooling needed and the boards/parts to some extent.
(3) The rails are +30V/-30V. The KGSSHV will have +500V/-500V rails and 580V bias. I cherish my life. 500+ volts kills.

My first DIY amp was a Dynalo+Sigma22+Jtree attenuator. If by Dynamite you mean a balanced Dynalo, then ask away- I'll try to answer everything. To be honest it's a very challenging first build with some potential issues poorly documented.

P.S. Never underestimate electricity. 30VAC is able to kill you if you happen to puncture your skin with loose wire strands. It's the current that kills. A current between 100-200mA is a killer, and all that it needs is a low impedance entry point into your system. Luckily for you impedance for dry and undamaged skin is 100000-400000Ohms which means relatively high voltages are needed to pump the killing current. Keep in mind that moist or damaged skin can have impedance below 300Ohms. You do the math.

New revised Dynahi is coming soon with onboard heatsink (easier and cheaper to build), different output transistors, less powerful to still far more enough to drive the HE6 or K1000.

Yeah... It's the current that kills. True that.


Survived a couple of 230V-adventures. Not even arrythmia after.


But, my point was. I want to try my wings with the Dynamite before I start playing with the KGSSHV.


And I will be taking som pretty radical precautions. Double sugical gloves [if we can use diathermia during operationswith them, then they isolate pretty well ] and rubber sneakers always as soon as the current is on and/or I suspect that caps can harbor nasty electrons in them.

A mock-up with some poor photoshop-touches, just to get a feel.
Yeah, I know the 4-pin XLR looks weird. Don't take it too serious.




I've read some stuff about the solders on the KGSSHV being a bit more dificult. 500V arcs easier than 30V.


So... I will take some extra precautions with that one. No rubber stuff with the Dynamite.
