Hi there folks
I'm a bit late to the bravo audio party - but hey I did finally manage to make it!
I got the Bravo V1 - with Russian tube about 3 days ago - and it's blown my mind - sounds so damn good. I'm using Senn's HD419 with the open vent mod and it sounds amazing - monster bass that is detailed and tight without killing the tops. Even my crappy AC97 motherboard sound card sounds musical with the damn thing - it is amazing.
Until today I switched on my little wonder amp - and bam - started pulsing - a 1 second cycle - the pulse is the LEDs starting from dim then growing bright (both LEDs) over a 1 sec period then starting again, repeating forever!. I did attempt to read every message on this post - and I found a few with the pulse issue - but no solution or reason for it. Because it's xmas time and sending it back from UK to HK is a no no, I suspected it was the power supply - I have no clue about electronics - so I jumped in and tried a 27V 2A switched power supply I had (creative labs speaker PS), using that it goes thru it's pulse cycle 7 times - then eventually works - sounds good again. Yaaay!
Does anybody know the impact of using a 27v supply on the thing - or even how to fix the pulsing - it seems like some sort of feedback loop (I'm guessing wildly here !!) that gets stuck. But before this happend it was amazing and I really want the thing to work again!
many thanks
