Kim, that turned out very well. Very sharp build.   Note about original power supply. These are included with Cisco's wireless access points and some VOIP phones. In a building that uses Cisco ethernet switchs the power for these devices comes through the ethernet cable so the little power...

Great looking case for your project! You finished it off well.

Cool design Vixr! I really like that.    Kim, interesting what you said about picking up wifi interference. I built my MHSS quite a while back, when you could still get the 19J6 for a couple dollars. All components are exposed on top of a perfboard, except resistors. They’re inside the...

Hi Tom. I didn’t buy the kit, yet, and didn’t have a pcb. I created it on a rat shack pc board. Ferrites are above board. I also created my own adapters for the amp chips and believe I damaged the ground. It was Sunday morning, I didn’t have any other chips and didn’t feel like waiting for...

Thanks all. Bad ground buffer. FA - Current draw right on the money at 24.8 mA CT - Only difference in parts is that I used caps and resistors I had in the parts box but they are all the same type and value. But you're right I should have went back to the site and read more. I've read...

Hey all. I’ve built 4 headphone amps previously and they’ve all turned out great. This weekend I started a new project and tried AMB’s Mini3. Not from the kit but from parts I had. Built it verbatim of the parts and schematic. It worked first time but … I’ve read that the AD8397 is a bit...

The power supply for this project is the Cisco PSA-18U. Like almost all computer equipment today it runs on either 120 or 240v. It powers Cisco wireless access points (ap) and ip phones. One is included with every wireless ap however its rarely used. Most ap are connected back to a Cisco...

To those of you who have built a GainClone and big speakers, use the Starving Student as its preamp WOW, WOW, WOW

For what it's worth I've never experianced even the slightest thump on power up or down and my primary set of cans are 32 ohm senns. At power on the tubes begin to glow and a just audible hum slowly rises. I followed the bom for the options schematic except I used 1000uF caps for C1, C6 and at...

Got a meat thermometer? A digital, like you would use for a roast or what I use when grillin' big ol' steaks or a pork loin would work. Bed Bath & Beyond - Oneida Digital Probe Thermometer
