    Happy New Year!! This looks really nice and pretty similar to what I had in mind...I built one years ago (p2p) which still works perfect and still have two of FredFred's pcb... Found a pretty cheap enclosure (around 19 € incl. shipping) which has all holes needed already milled. This has the...

    Hi there... Next one alive and behaving quite good, no noise and only very very little hum.     Things left to do : order some slightly larger knob and add some paint. Cheers

    For the LED's and the stock PSU , I added 3 (switchable) at 7mA and 17mA, and the amp turns on just like before, takes like 2-3 seconds for the tubes to light up. I did not do any measurements yet. Seems to work alright. I might look into the voltages before putting it into the case...  ...

    Quote:   I already have a on/off/on switch with center off, where did you put this in your circuit? Values for 48V with 5000mcd red 2V LED : 3,3K 2W for bright @ 15mA / 4,7K 1W for dimmed @ 10mA and 10K 1/2W @ 5mA for the power LED Did your build have a power LED?

    Hi, I have the stock PSU with 48V 380mA, after moving it to another outlet, away from my laptop PSU, its perfectly quiet. But its not in its case yet... For the switch, its a "miyama ms 169" and I found it to be odd that it didnt worked the way I thought it should, like KimLaroux said. I...

    Hi there, beginner question again: I'd like to put some switchable (dim/bright) tube led's and a power led into the circuit, would this be correct for the wiring (switch wiring lower right) ? Or is there a better point to hook up the tube led's?   Need to check for the proper...

    I wired c3 + c5 to the output, but not to the rest .... Sweet music is playing for 20 minutes now, i got some 50hz buzz, but i think thats because of my laptop wallwart. Already had that with other equipment. Thanks to the_equalizer  :) Next : Casework

    hi there, nice to see theres still something going on in this thread!!   since my first try on the ssmh 12au7 has been hiding in a box for way over a year or even longer, last week i decided to redo it with some perfboard. Mostly because my old build (not working) was just a mess of...

    hey thanks for the tip with the resistor, the mosfet was fried , swapped both and now its back working, tube seems to be ok :) Don't have any cheap headphones to try right now, so there's something else to do hehe I forgot to install the socket mounting ring ... Think it's time declutter...

    Oh oh.... thanks to a pic Aflac has on his picasa acc. I had it working yesterday , had something wired completely wrong before ...after rewiring , both tubes lit up, mosfets got hot, tested as the_equalizer posted @ page 259, seemed fine... Today I was double checking the voltages before...

    Hi there... Oh well, just finished soldering all the parts together, what a mess!! Thought using a Star Ground like this  http://mark.rehorst.com/LM3886_amp/amps_chips_and_star_ground.jpg would be a good idea.. It wasn't. Loads of extra wire...   Would it be a bad idea if I used a...

    hi there, lovely @ meme, the gold and teak/black fits perfectly imo!   I didn't even mess with a possible enclosure yet need to source the parts first hehe. At first I thought about doing something in engineered stone/marble/granite, but regarding the size... almost impossible for me...

    Hi there Head-Fi, First post, my name is Marcus and i'm from germany, excuse my bad english. After reading most of this thread (which took quite some time), I decided to go for a build even though some parts got me confused. I have some soldering experience and from the many great...
