I'll be getting my Ocean soon, will get into tube rolling I think. Not sure which is the best way to go if I want a fairly balanced sounding tube
I had something similar. I presumed it was damp or condensation after the journey from China and lying in a cold store room and delivery van. I just left it switched on with no audio signal input for 4 hours and also took a hair-dryer and blew warm air all over the connections, including into the tube sockets.
After the 4 hours I tried again and the problem was gone, and has not returned.
Good luck-it's worth persevering for the excellent sound.
Failing that you could try another tube, just in case there is a problem with one of the pins of the tube provided.
Hello, I was wondering if anybody would be able to shed some light or supply some insight/tips on an issue I am having with a new Bravo V3.
It arrived in the mail this afternoon and I was super stoked to get to listening. (I was reading up about them and knew about burn in times ect...so I was expecting to have to wait for the sound to blosom...) but I loved the sound...was very full and great...until about halfway in to song 2. so maybe 5 minutes of playing. the red and blue led's turned off and there was a loud pop then a whole lot of awful crackling. this happened a few times in a row after letting it sit unplugged for a bit.
I was getting frustrated and started reading up fixes...but didn't really find anything...all I assumed was it was a power or heat issue. when I crank up the voluem when the tube is out but the power is on its crazy crackly but still the music is audible. at this point i started blowing on the heat syncs and then the leds came back on after a few seconds...
I now have a desk fan hooked up next to the amp and that seems to be keeping it running fine. and the sound is great. I have the option to return it to the supplier...but that would mean a few months turn around. I've been waiting a month and my HE-400's are due tomorrow or the next day.
Are there any known fixes for the V3 overheating? or mods that can be made relatively eaisily to the case and or the heat syncs to let it run at room temp. (my study is quite warm from multiple pc's running 24/7)
I've also adjusted the voltage dials? on for each chanell to drop the heat down...they are sitting at about 14.5 each. (they were set around 20-22 from the supplier...)
Thank you in advance for you advice/wisdom.
Cheers,
Andrew
Just received my V3. Pleasantly surprising. I didn't expect the EQ to actually work, or have semi-decent channel balance.
I haven't used the HE400, and sibilance isn't a problem I have met with so far, but I seem to recall that quite a few people have commented on the need, in general, to equalise the treble with the HE400 to reduce sibilance and other high end issues. If it's any help, and it's only speculation, you might try the gold pin version of the supplied EH-6922, or a vintage Bugle Boy, Mullard, or GE 'dark glass' as they are all smoother at the top, but it's really just a question of trial and error and it can get quite expensive.
hey guys, what tube would you recommend for reducing sibilance? I have the HE400 and I am still adjusting to the silibance. I found EQ-ing works quite well, but I want to see if perhaps different tubes can cause sucha drastic improvement in sound.
The stock tube that came with mine was in fact a 6922.
I have not noticed any real difference in sound signature/quality between 6922, E88CC and ECC88 tubes by the same manufacturer, but there is certainly a difference between different manufacturers' tubes. Even so, these differences are not usually huge and the V3's equaliser can sometimes create similar changes in sound, which could save you money buying too many different tubes. But then, part of the fun of tubes is rolling them.
