I'm looking for a strain relief, such as Mouser 561-MP3P4, 561-MP2M4, etc. for a project. I'll be using it with some sort of star-quad cable (Mogami, Canare, etc. whatever). I'm not sure how to properly size these. I'd prefer a round panel hole. Has anyone ever used one of these with such a...

What's an acceptable amount of DC offset to have during turn-on / turn-off of a headphone amp? Here's what I have: This referenced to ground. Which brings up a few questions. In a bridged amp with four identical channels (i.e. "balanced"), is there any way to predict the polarity of...

Looking for a hex inverter, 74hc04 style for bringing up lines to TTL. Need 6 total buffers. Lots of options, and not really sure what parameters (if any) matter. Surface mount is fine. Any opinions?

Just curious, what are your opinions of vias located on smt pads? Good? Bad? who cares? The packages in question are 14 and 16 pin SOIC packages and perhaps 1206 resistor pads. The hole diameter of the via would be 15 mil and the annular ring 25 mil. Is solder stealing really an issue, or does...

ok, so good idea or bad idea?! I'm using noval PCB mount sockets. The idea would be that I'd put a screw through the top side and screw on the standoff on the other side, then solder in the tube socket. I don't have a center hole in my socket pattern... I figure the screw will be trapped, but if...

So, what is this thread about. Let's show how powerful the DIY community is here on Head-fi. This would be a first, on Head-fi but need not be the last time. Why, swt61? Why not. The details. At the recent Houston meet, we were listening to swt61's Beta22 at full volume, as the source was...

hm, found this: 8GB Cyco-V39 / Teclast T39 ***Free Shipping*** Any idea if this is legit? If I use Google Checkout and go for it, is it possible to protect myself from fraud?

for some reason I cannot seem to find these anymore. They are a 8-PDIP socket with an integrated bypass capacitor. On a side note, has anyone used these for audio opamps?

Hi! I'd like to put the characters 中盤 on a amplifier project I'm working on. Unfortunately, they need to be in HPGL and if at all possible, I'd like a somewhat artistic interpretation. Would anyone be able to give me a hand with this? Thanks!

Does anyone have a good way to get illumination behind a knob to be consistent? I am trying to use a couple diffused LEDs with wide viewing angle and it still looks splotchy. Perhaps a piece of perspex could be used here somehow to act as a diffuser?

Hey, I really don't need the quantity of these being offered on Ebay.. I actually need 4... value isn't important, but I need the smallest dimension (width?) to be less than 8.7mm (11/16").. height and pitch aren't really that important. Anyone have some laying around, or know where I can get...

Hey! I'm looking for a SLA charger than can handle a pair of 12V x 18Ah (at least 18Ah) batteries, or single 24V battery if the chargers are paralleled. Must have "smart" charging capabilities. I've found one part that fits the bill, Digikey PATC-08-ND but I'd like to see what else is out...

I'd like to match some 2SJ74 and 2SK170 JFETs by Vgs and was looking for a good way to do this. What about something as simple as the attached circuit, which was proposed by Nelson Pass to match the Lovoltech power JFETs. See attached. I also found this circuit, but it seems to be a bit...

I forgot to add 4 1000uF/50V Panasonic FM capacitors (P12393-ND) to my last Digikey order... anyone happen to have some on hand, or about to place an order and wouldn't mind shoving 4 parts into an envelope and sending them my way?

I'm finally getting around to replacing the blow fuse in my DMM. I've been using the unfused probe input for a bit now and am wanting to go back to using the fused input. The meter is a BK 2706A and the front of the meter says that the limit is 200mA. The manual is located at...

well, according to Digikeys search, they don't carry anything in this footprint... Mouser for some reason won't let me search by pitch, but I know they carry the Wima MKS02... anyways, what options are out there in this footprint for polyester / polypropylene caps? Thanks in advance!

I am in the need of a very thin piece of material that I can put between a PCB board and a aluminum chassis for insulation purposes. The amount of room between the PCB and the chassis is uncomfortable small, probably the width of a #6-32 nut plus a thin washer. My main concern is some tube...

I've been looking at a few output stages, namely the Wadia 27ix and have noticed these devices used in several high end players and DACs. Anyone used these before? Do they perform well, or are there good upgrades / drop-in replacements for these out on the market now? Seem to sound good enough...

I'm looking for something like these strain relief bushings, but for smaller wire. Say 18ga or so: http://www.mouser.com/catalog/632/1628.pdf Honestly, even a rubber gromit would work, but this returns nothing at mouser. Surely my search skills are lacking... are these called something...

has anyone heard or seen any reviews of the new Sony reissues? Of course, I have to get this one: Question is, should I just get them all

ok, I accidentally ordered the wrong part from fastener-express... the alloy steel is black, and here I've been ordering the black oxide this whole time. Seems that alloy steel is a bit nicer, heavier, and doesn't mar as easily. What's your opinion?

So, I have two stacked toroids in a case that are secured to the bottom of the case via a bolt. The top of the two toroids is secured using one of the metal dishes that often comes with toroids. Problem is, that the stack is really close to the top of the case... probably 0.25" clearance. The...

just curious, anyone have an opinion of Barenboim's Mozart Requiem? I have it on Angel S-36842: Sheila Armstrong - soprano Janet Baker - mezzo-soprano Niccolai Gedda - tenor Dietrich Fischer-Dieskau - baritone John Alldis Choir - John Alldis English Chamber Orchestra - Daniel Barenboim...

Does anyone know of a top adjust potentiometer that fits "well" into a RN60D resistor footprint? Thanks!

I am thinking about putting a long heatsink on top of a aluminum case, perhaps one of the new FPE cases. I was thinking about cutting holes in the top of the case and mounting the devices through the case directly on to the heatsink. I could either use small ceramic spacers to decouple the case...
