DIY Cavalli CTH Compact Tube Hybrid Headphone Amplifier. This is the second one that I mount. The first one was few years ago, and the only thing that I fried was a couple of transistors BC337/BC327 that I swapped (PNP for NPN).
This time I have reversed 14 rectifying diodes
At the PCB they are marked with a circle that I assumed was the cathode pin (the cathode is marked with a band at the diode), but not. That was the anus 
There was no smoke, and I only applied power for less than 30 seconds, until I realized that there was no Voltage at any of the 3 power supply circuits.
I have already removed them all. They are OK. I am wondering if the electrolytic capacitors or the regulators after the diodes have been damaged
What is the latest Destroyer Medal that you have been awarded?
