Hey guys,
I bought a Bravo V3 about a year ago and decided to finally start modifying it. I work on with digital electronics for a living, but I have to say that I'm totally inexperienced with old school audio.
Got a few questions for you guys,
Lately I've been hearing a lot of more noise through the amp. From the sound, I believe it is some sort of interference. It's a "digital" sounding noise, not a hum or hiss. I don't keep my phone too close, but my amp is right next to my computer. This is my office setup, so I don't really have too many places where I could move the amp. I've had this noise since day one, but it seems like it happens more and more often now. Any clue what could have changed to cause an increase in this noise? Maybe my office had some new electronics installed? WiFi?
Has anyone upgraded their power supply? Were the differences worth the upgrade? Please provide links if you bought something good.
@Euf0ria, did you do each capacitor upgrade with a test in between to hear the differences? I'd be interested in hearing how each impacted the amplifier. How did you choose the values for your capacitors? I wouldn't know where to start myself. I'd be interested in your take on how the different values effect the circuit, especially the output capacitors.
I've started reading Bravo V1 tube rolling threads, but there is a ton of information. Have any of you guys found a suitable tube replacement that you really like? I'd love to start doing some rolling myself, but NOS prices are a bit much for experimentation. I'd like to see some improvements on the low end from the EH, as I listen to metal/hip-hop/techno which is all pretty bass heavy.
I'm planning on doing the IRL510 upgrade first. I looked at upgrading the LM317, but I don't think this will benefit me too much. The TI LM317AT has slightly tighter specs than the original LM317T, but I really don't know how much that will effect things.
@Didhefocus thanks for the EQ bypass switch pictures, I will most likely add that on there too!
