Hello all,

Sorry if this has been covered before, or if it's a really dumb question..   I looked back about 10 pages and couldn't find what I was looking for so here it goes. 

Does the volume level matter on burn in?  I plan to run my modded SB3 and linear PS 24hrs a day.  Luckily this will be in my basement theater, so as to not bug my wife (stay at home) too much.  However if the volume is loud and annoying I'm sure I will hear about it.

Thanks in advance.

If you're only burning in amp/pre and not speakers, just drop an 8 Ohm 10 or 20 watt resistor (Radio Shack) across the speaker terminals on the amp and call it a day. If you're also burning in speakers, just place the speakers face-to-face and wire one speaker out of phase. Hit the "mono" button (or play mono recording) and the sound from one speak will cancel that of the other. Simple, safe, and doesn't piss-off the wife.

Thanks for the response EW. 

I guess I should have been more clear, I will be burning in my (bolder) modded SB3, and linear PS.

I ran mine full volume 24/7 into a preamp input as a load and mostly left the power amp off.  This way there is some current flowing through the output Sonicaps.

Tom,

Thanks for the reply. 

This is exactly the scenario I was hoping for.

Shaun,

Depending on the load your pre-amp presents, you might find the SB would "burn-in" a bit quicker if you put together a couple of RCA males with 10K resistors across the + and ground. This will cause a bit more current to flow through all the caps. Maybe you have a CD with some "burn-in" tracks on it. I would rip that to flac and keep the SB on repeat that same track for as long as possible with the load resistors across the RCAs. Keep the volume on maximum.

Also keep the display on the brightest setting, as that also requires more current to run through the PS caps.

Hi Wayne.
Still a bit confused about the burn-in for the digital mod. Since it is the DIGITAL output I'm burning in, did you say to just put a 10k resistor from the center conductor to the shield of a single RCA plug?

Thanks,
Gary

Gary,

The 10K resistor is for the analog output.

For the digital, there is no need to add any resistor. Just keep the coax digital output plugged into your DAC or receiver and keep the SB playing.

There is no need for the DAC or receiver to be turned on.

Can I do both of the above suggestions simultaneously  ( analog side and digital side ) to cut the time in half or will one output override the other?

Thanks,

Rob S.

Of course you can do both, but I do not believe it will cut any time off.

There are quite a few Black Gate caps used in the internal power supply mods. These will take 300-400 hours no matter what you do.

The Sonicap Platinum caps that quite a few folks have in the analog output path can take up to 1000 hours of use to fully stabilize.

I just assembled a "modded" Burson Buffer using Black Gates in the power supply board and in each buffer module. I have run it all day and it was sounding really good.

Now, after about 12 hours of contiinuous play, the typical sound of break in is starting to happen. This is when the highs suddenly start to become very prominent. In the next couple of minutes the highs will go away and the bass will come on very boomy.

This will continue for the next couple of weeks.

The only way I know to speed things up a bit is to use something like the FryKleaner signal on full volume into a lower impedance load to cause more current to flow through the caps.
