diy amp

I want to start off this thread with a bit of background in regards to my personal DIY journey. Since about 2012 I have been what people call an "audiophile", but didn't get into tube amps until middle of 2022. Well, needless to say I got hooked on the notorious "tube sound" and now am a proud...

It happened - I've been bitten by the DIY bug. This thread will be where I leave my thoughts and write down design decisions along my DIY amplifier journey. It will range from the most basic stuff, like buying equipment and setting up a workbench, or biasing a tube and experimenting with how it...

Hi all, We've got something cool brewing that we'd like to share with the community. It’s Ugly, Naked, and Small. The Gremlin DIY Tube Amplifier is a little monster with a ferocious bite. Packing 1250mW of output power, it’s got the muscle to drive nearly any headphones that dare to cross its...

Hi, I purchased an amplifier with a damaged Pre-Out, see pitcures below. To me it looks like only the metal cap is missing. So is it possible to remove a metal cap of another RCA and mount it by pressure to the amplifier? Or do I need a new RCA that must be soldered to the amplifier? Image

I'm creating a thread for an upcoming DIY project I am working on, a tube headphone amplifier called the Aegis (pronounced EE-jis). This is a true DIY project, anyone taking on this project would assume full responsibility for acquiring parts, building, and testing the amplifier, although I...

Great news for the headphone DIY community; Pete Millett has released his Sengaku design as a DIY friendly offering on his site: http://www.pmillett.com/sangakuDIY.html The original was a TTVJ offering in 2016 for $2K. Changes include swapping SMD for through-hole components and ditching the...

If you frequent the DIY forum here, then there's a good chance you know about Kevin Gilmore and his contributions to the DIY design library. From Dynalo to Dynahi, to top of the line electrostatic amps like the KGSS and it's fancier cousins. Less known are his current feedback designs for...

I built a Cmoy amplifier as my first DIY amplifier project recently, based on Tangent schematic. After testing it, the output sound feels fading, wide and missing some of the sound, like some of the vocals and instrument cant be heard (not sure how to better describe it), but it doesnt sound...

TLDR; Taking my current Odac/Objective 2 + Stax SRM-252s setup and building it into a single chassis, while adding VU meters. Please skip to the Challenges section, because I do need some help with this! Inspiration: Stax SRM-212 Protype (Showcased at CES2016) My imagination. The actual...

Hi everyone, I have a small amp that I put together. Couple different versions that I am planning on selling. I would like to post some really detailed specs about it but I do not have the necessary testing equipment. Would anyone with the right equipment be willing to do some testing and...

Ok Headfiers, this thread was sleeping and I decide to wake it up....since I have way too much dongles and DAC-AMPS that i didn't share impressions about (thanks to this 1 year pause due to pandemic). I want to make a kind of Best DAC-AMP quest here, for everything under 500$, it will take...
