Got a bit of a shielding question I didn't see answered - I've recently started using my Starving Student with my ER6i and/or RP-21, as opposed to my 80-ohm DT770s. This combo of lower impedance/higher sensitivity has led me to notice a quite obnoxious rendition of my college's FM radio station...

After some digging around, it seems that Tripath Inc merged with Etelos, Inc and then proceeded to drop off the face of the earth. Their website is down and I cannot find their products at any supplier I would normally source from. I'll keep looking. EDYTrade looks to be a reasonably...

I sprung for one for my Vogue... My MP3 player is a lost cause

When you had both left and right routed into the single 1/4", were you using a stereo 1/4" plug? If so, I would bet the signal was being interpreted as a balanced input, hence your issues with distortion. I would use each 1/4" input as mono, with an adapter such as this (or one of the...

I keep lossless copies of all my CDs on the computer for archival purposes - my Zen receives LAME V0 transcodings of those. With my current gear, I can't discern a difference.

Quote: Originally Posted by TimJo I think so. I ended up getting 2" heatsinks so they would be taller than the tubes, and they don't get that warm. Plus they are mounted on an aluminum case, which dissipates even more heat. Good point - mine are mounted into wood. I may look...

How warm are everybody's mosfet heatsinks? I used the standard ones from the BOM, but they are very warm to the touch even after just a few minutes on. Is this pretty normal?

Your link is a little screwy, arande2. Looks like you have an extra "http://".

I have a pair of Sylvanias and an RCA Victor; along with a Hytron that appears to be an RCA rebrand. I can't discern any difference between them from a sound standpoint.

Quote: Originally Posted by TimJo It's hard to describe things based on the pics, but looking at the close up of the terminal strip with the yellow power wire, it looks like the gate on the Mosfet (pin 1) is not attached in the correct place. It looks like it is attached to the fourth...

The mosfet's are correctly wired - each line from pin 1 returns to it's respective lug on the terminal strips, each pin 2 returns to 48v at the power switch, and each pin 3 returns to it's respective pin 3 on the tube sockets. I understand how it would be hard to discern exactly where a wire...

Picasa Web Albums - Chipp - Millett Starv... You should be able to zoom in quite a ways if the default is not large enough. Thanks for taking a look. EDIT: After triple-checking things, it appears I left out 2 of the 2K ohm resistors. However, looking at the schematic, Pete and Nate's...

Well, I went ahead and build the second (left) half of amp today completely ignoring how I built the first section and going solely by the schematic. It ended up looking the same and, unfortunately, functioning the same as well. I tried my "tester" Hytron and RCA tubes first, but when they...

Thanks for the tips guys. I made the aformentioned corrections regarding pin 4's grounding and the resistor between pins 7 and 4 in addition to doublechecking the 1/4" out and wiring ground for the pot. Still a lifeless amplifier though. I do not see any visibly fried components, but I may just...

Good afternoon guys; I got going with my build yesterday and after a few hours of casework and a few more hours of building I finished all the inputs and the right channel of the amp. I checked things one last time, plugged in, and flipped the switch to get nothing (not even smoke or flames...

Tangent Tutorials Some excellent information there for anybody looking to get into DIY, the soldering tutorials are particularly good.

Ugh, these darned things arrived in the mail today. Looks like I have to build an amplifier now.
