I have encountered a massive breakdown on my power amplifier...
The story was like this, one day with the amp power on I tightened/snugged up the speaker binding post. There was a single frayed strand (unnoticed) that shorted. The amp proceeded to billow smoke. I looked inside to find power supply caps having oozed their electrolyte onto the circuit board.
A more likely scenario is that the short damaged the power transistors, and they in turn caused the capacitors to fail.
I am trying to rectify the amp, however I do not want to waste my time if there is likely to be damage to the circuits other than electrolytic capacitors.
I like an amp that is there to do it's job and do it's job well. To me that is something that acts as a conduit between cd/pre/dac etc., and the speakers.... something that can deliver grunt when required and also be delicate when needed. Something that can play quick dynamic music as well as it can laid back music.
In other words, I want my amp to sound like nothing.
In searching for an alternative DIY amp, contacted Aniket... he offered me this:
"We also have a more powerful version of Discrete Dynamics power amp. Transformer requirements 43-0-43, 600Va and 9-0-9, 5VA for protection. It will give you approx 200W/channel in 8 Ohms. The minimum driving load shouldn't be less than 4 Ohms."
Rated power output and build quality looked impressive... so, ordered one stereo module.
