I'm looking for a piece of equipment that will do the following: - Convert a headphone output to two balanced outputs - Convert a balanced line output to a headphone output. Does this exist? I've spliced some schematics and could build one myself. I'm just hoping somebody makes one!

My Behringer ECM8000 had a problem so I opened it up. The first time I tried to pull the guts out it required a lot of force, so I gave up, because I needed to use it. I opened it up tonight with force and ended up breaking the wires that lead from the capsule to the pcb board. Yikes!! How...

I'm building a preamp for an Audio to Digital converter and am looking for a schematic for a clipping indicator. I want the "clip" light to turn on just before I hit the 5V peak to peak threshold. Anybody know where I might stumble across such a circuit diagram?

Hi, I'm building a mic preamp with +12V and -12V on the rails of the opamp. How can I convert this voltage difference to 24V phantom power? I know it has to do with how you hook the resistors (usually 6.81K) up... Do i just send +12V through on resistor and -12V through the other...

I've been looking for a way to get a line out from my plexi.... I have a berhinger D.I. box and it mentions that I could use it to tap the output of the power amp, but it doesn't mention how this is done, really... see section 2.4 of this...

Okay, So it doesn't have much to go with guitars, but I'm pretty stoked about this!! My old power supply was SO noisy!! I put a Seasonic S12-330 in it and now I can't even tell when it is on... mostly... the CPU fan is now the noise culprit... NO MORE HISS AND HUM in my acoustic guitar...

I thought I'd give us all as chance to post tips for using our accoustic electric guitars.... here's mine: Compress the Hell out of them!!! I hate the sound of those Klacky piezo pickups and thier harsh harmonics. I deal with them about 90% of the time in my line of work...

Well, I have outgrown my old amp. I am currently just using it as an extension cabinet for my Vox AC30CC head. I have a 30W blue dog in there. I'm looking to sell the amp and then buy a cabinet to put the blue dog in. What are some good sources for unloaded cabs? I'm think a 2x10 cab with a...

I have had a hard time finding a good schematic to work from. I would definately want a schematic that was not set up as a straved current/plate circuit. Anyone know any good source for these kinds of schematics?

Okay here's the deal. My dad gave my sister his old 1952 Gibson LG-1. She never plays it because it has a HUGE crack that runs along pretty much the entire bottom side of the guitar. I've talked to her about letting me have it so I can fix it and play it. She said that she would trade me for an...

Hi, I'm looking into getting a tube preamp. I see a few mallsingle channelunits around like the ART and the Behringer. What kind of tube preamps have you had experience with, or would you recommed? I have heard that some of them sound best with a lower gain tube than a 12ax7. Are there...

I just finshed my rebuid of a Gibson GA-5 Les paul Jr amp... It is working good except that when I turn the voulme knob past a certain point I get this really BAD distortion, like the speaker is cutting in an out- we're talking some SERIOUS clipping.... I tested it earlier with an...

Hi, It seems like I am always answering posts about speaker impedendances and what kind of problems a mismatch my give you - They seem to turn up every few days or so. I created a webpage that should explain all this stuff, including diagrams and comouter simulations showing the...

Okay, so I modded my amp (DSL401) - adding birght switches to both of the channels, removing a unnessasary capacitor that was limiting the bass response and added pin jack to the back of the amp so I could check the bias without taking the amp apart. So i put it all back together and fired it...

I was just finallizing some specs for my new amp project, and I got to thinking - what would it sound like if I put a choke in my current amp? it currently uses a 470 ohm 5W resistor, but I may be able to replace it with a 429 ohm 75ma 14H choke for $15. Maybe even make it possible to...

Hi, I am planning on building my own custom amp based on the Marshall JMP 1987. For now I will just be building the power amp. It will have lots of custom options like pentode/triode switching, fixed/cathode bias switching, feedback switching and possible variable feedback, post phase inverter...

So I noticed last week that the plates on the EL84's in my DSL401 were glowing. The tubes has been incorrectly set up (biased WAY hot) due to a miscalculation and the fact that the four tubes share the same bias setting..... I kept putting in different tubes (spares) and finally found a set...

hmm........ -------------------------------------------------------------------------------- Okay, I hear this one WAY too much and it has never made any sense to me, so I would like to clarify a bit.............. Then are two different types of measurements when it comes to Power supplied by...

I was at guitar center today and was just on my way out the door wheni saw the Vox Tonelab multiFX pedal. I didn't want to choose another guitar and then play it through a crappy amp, so I just turned it on to look at it. I noticed that the "glow" from the tubes appeared instantly. That seemed a...
