Simple question but I can't seem to find an answer. To wire up the attenuator pictured below as long as the two tabs for each deck are wired together does it matter which way the two are wired up since it's just placing a resistor in the signal? Also I'm assuming the tabs I've circled below with...

I've looked around at various builds but I wanted to double check that you do not in fact need to connect the shielding when using shielded cable for hook up wire. I'm going to be connecting single ended outputs to an output stage.   Some pictures look like the shielding is connected while...

For anyone who has used Front Panel Designer I'm looking at the various dimensions for some common Neutrik chassis connectors:     http://www.mouser.com/Search/ProductDetail.aspx?R=NF2D-B-2virtualkey56810000virtualkey568-NF2D-B-2...

I have looked and looked but cannot seem to find a 4PDT rotary switch. Does anyone have any idea where I can find one? Preferably it would be a on/off/on switch. 

I currently have the multimeter I purchased at radioshack - the no frills $20-30 model.    Short of purchasing a much more expensive multimeter is there a good way to match resistors?

I haven't seen s pre-built pot with SMD resistors before on ebay. I've been looking for a good balanced pot but am not really sure if this falls into the good deal/ decent performance category or definitely not worth it. Any thoughts?  ...

The pictured ALPS rk40 is a stereo pot NOT balanced correct?

I had been hoping Rockbox made its way to android someday and I just saw they've released an early build   http://www.rockbox.org/wiki/AndroidPort   Just installed it on my droid incredible and have begun trying it out. Still very much in early form but if this keeps getting worked on it...

I want to use a connector like the one linked below to connect my S11 to a balanced M3 - so I have to run 4 wires. I've looked at the data sheet for these Amphenol connectors  ...

I purchased some OPA627AP op-amps from a seller in China on ebay and received these. They don't have the trademark sign next to the BB logo or the notch in the side every OPA627 I could find online does. Could these be fake? They weren't particularly cheap so I have no reason to think they're...

I know AMB used a Jameco wallwart case for the ck2III (The Cavalli-Kan Kumisa III Stereo Headphone Amplifier) but was wondering if people just buy a regular wallwart and then open it up to put in their own transformer or if it's possible to buy an empty wallwart case. I've looked around and...

I'm looking for recommendations for a fairly comprehensive book that covers the basics of electronics that will give me a solid technical understanding to tackle most DIY projects. Maybe that's a tall order, but any direction for any sort of material to look at would be appreciated. I'm...

I doubt this is possible but I was wondering if there might be any way to set a DAP to some sort of pass through mode so it could be connected via USB to a computer and play whatever is played on the computer. For example my laptop has a sub par headphone jack but I like the sound from my...

Perhaps this is a bit of an oxymoron but are there any self powered monitors that accept a balanced signal that are relatively low priced? Or if there isn't much of an improvement to be seen any thoughts anyone has would be great.

I am mounting an Alps RK 27 pot on the front panel of my headphone amp and the shaft is much longer than the stepped potentiometer I'm also using. For the life of me I can't find a knob that will cover then entire Alps shaft without being too far away from my front panel and looking weird. I...

I've searched hi and lo for an answer to this but please forgive the dumb question. I have my AMB M3 wired up as per the instructions in their site for an external psu. RCA jacks and volume pot are connected to the chassis while DC input jack is isolated. Now on my STEPS PSU at the moment I...

After joining the forums towards the end of last year I got interested in getting a nicer headphone amp. After buying a LD MKV I think about a day went by before I decided to buy the TPA Buffalo kit. It wasn't long before I wanted an M3. It's been a slow process but I finally got my...

I would like to buy one end plate for my hammond case (1455T2201BK) but only see them in packs of 10 on mouser and digikey. Are they sold as single pieces anywhere?

I'm wondering if it will make any difference sonically if I use some nice copper wire I have for L/R channels and some lesser wire for ground on a single ended headphone output? I'm also wondering about RCA outs. I could see how the ground channel on a headphone out might have an impact but...

I'd post this in the headwize M3 thread but its down. I am trying to figure out what terminal block to order for my M3. You can see in this picture (http://i23.photobucket.com/albums/b3...hski13/009.jpg) There is a 2 position terminal block used to connect the power lines to the board...

Barring the benefits of a shielded vs. unshielded transformer do you all find the various brands can affect sq for better or worse? I'm talking about for use in DAC's as well as headphone amps.

I bought this cheapo case not expecting to use it for too long but I like the size and will be able to fit everything I want for my DAC into it. At the time I also purchased the top for it (actually supposed to be the bottom as you can see in the pics) but was just cheap aluminum and had...

Unfortunately with the headwize forums closed it has been difficult for me to find help with an M3 amp I have. I have an M3 with a STEPS psu and am trying to figure out a solution to what I believe is a grounding problem. Those with M3's are familiar with the sound the amp makes for a...

Would scratchy and quiet sound be an indication of blown opamps? Thanks.

Having never opened up my SR225's I was wondering how difficult it might be to replace a blown driver in them? Or if Grado would even sell me an individual driver.
