Well... it's a great place to listen to the music loudly, with tactile effects, without harassing anyone :)  Then the ambient noise is not an issue anymore, and with some EQ you might get the acoustics okay sounding :)

These (and similar LipSync) ICs, they do it in digital domain: http://www.ti.com/product/tpa5050   Will need to split and merge I2S channels, might be a glue-logic hack (LRCLK-driven MUX gate on the DATA trace). For R channel i'll get the LipSync delayed data, and for L channel - "before...

Thanks! I might mix the options with Neutron's software PEQ and a time-delay in hardware (i design DACs on daily basis so it won't be much issue AFAIK, i already have some IC on my mind for the delay...). Or go with beaglebone with an android phone as a remote... Well, this will require...

Oh my.   I'm trying to figure out how do i replace my old iRiver h120 in the car with a brand-new-awesome-android-phone.   I'm looking for an app to be able to... 1. Play music, including lossless stuff 2. Handle directory-based navigation 3. Have DSP plugins with open-source framework...

What are limitations of B+ supply? I think of rolling-up the currents... My trafo is rated for 200ma, and i use just ~66ma.   The issue i try to deal with: There is some threshold in the amplifier. It sounds like "noise gate" - i hear the large-signal music and it's low-signal...

Quote:     There is reason for such ascetical design :) I have'nt found any push buttons that could pair with my cases - so - no buttons. Power switches on the back are fine too. The TRS jack socket looks ugly imho, i have already ordered a proper one from Neutrik (with metallic hex...

Thanks! It's 45x25 knob from eBay. http://shop.ebay.com/i.html?_nkw=45x25+knob&_sacat=0&_odkw=volume+knob&_osacat=0&_trksid=p3286.c0.m270.l1313   The cases are from WonderCo http://stores.ebay.com/wonderco-buy79/Metal-/_i.html?_fsub=2037457011    

And, yet another Bijou came to life!      The whole rack:  - Bijou  - GainClone /LM3886/  - DAC with SAA7220/TDA1541 - under heavy tweaking right now.   And some wires: http://s3t.it/cool/rca-wires-high-end-on-budget/

Yay, it's working :) On my ol' 565 sens - just for testing. Weirdly enough, it doesn't produce any hum although the power transformer is so close to the circuit. Probably star grounding and shielding signal wires helped a bit...   The thing which worries me - are the clicking/popping...

Ok, it seems i'vefigured out what's the problem. The transformer seems to be weak.   The trimpot regulates well the 240-246v, but it won't let me rise the voltage up to 250v - nothing happens when i turn it futher.   I've got pretty high load with these russian tubes, so maybe CRCRC...

The mosfets are right, caps too...     Cleaned-up the tubes, removed thermal insulation tubes off PS CRCRC resistors - the amp quit smoking    Hm... The behavior of +250v of mine: Slowly rises during startup (10-15 sec), up to 252v. (it stays at zero for 5-7sec , then rapidly...

Hi, tomorrow is the day. I have already powered it up, but it smoked a bit, so i'm asking for your advice: Should i let him smoke for a hour? By "smoke" i mean the scent of something getting hot. Burning oil on the tube's surface, paint on power supply resistors e.t.c? Probably i should...

Hi all!   I've run into some problem with a power supply:   The SOHA II requires 2x15v 1a PS with 300ma tubes. 30v*1a = 30VA. All i have are: 15x2 18va x7 15x2 25va x1   And i plan to use russian tubes (6.3v 600ma heaters). Therefore i need to get 1.5A PS for the whole board...

well, than it's ok, Do you plan to control the volume with the same pot?

Wouldn't work. The pop comes from the amplifier itself no matter what is connected to it, when it turns on. And your pot would just disconnect the input of the amp, so you'll hear the pop as you always did. Try it with the volume set low and you'll still hear the pop. The quick and dirty way...

Hi! What is the height of completed board excluding the tubes? The radiators are 25mm height (as stated in their datasheet), is that correct? I want to fit the SOHA II into 38mm (internal) height case with holes for tubes in the cover... Is that possible? Thanks!

Fake. If you want ok cheap station then these fhakkos are fine, better than any simple irons., but if you want to enjoy soldering, then you'll have to go with real hakkos.

Hi! I'm building the Bijou right now and got a question: I use a toroidal transformer from Antek-inc, and it has double 6.3v rails 3.5a each. Should i take one winding for PSU and other one for amps, or that doesn't matters much as it's just a heater supply? It's going to be all-russian...

3 months ago i got these pmx100. At first, i was a bit confused, because their highs sounded too loud and crisp, so i felt some pain in ears/head. Moreover, they seemed uncomfortable because their hard foam pads. I tried to soften them as mentioned on some Grado topics, with no success. Then, i...
