That's a beautiful amp, congrats! Is that a phono ground on the input side?

Thanks :) Yes indeed it's a phono ground. You can read a little more about the Seduction Phono Pre here if you have any interest: http://www.bottlehead.com/store.php?crn=220&rn=429&action=show_detail

 

It's a nice easy build. The only mildly tricky part was the C4S upgrade, as a few of the through holes are a little too close to each other so you have to be careful not to bridge any gaps around the transistors.

That's interesting as it could be used as a phono stage in a pinch, are the output RCA's amplified or pass-through?

 

edit: never mind, it is a phono stage, not a headphone amp!

Finished this one a couple of weeks ago. It's pretty much a standard build using AD8610 opamps. I splashed out a bit on a TKD pot, the amp is very quiet.

Case is made from reconstituted 5mm aluminium for the top, bottom, front and back that I've brushed and clear-coated. Sides are made from galvanized steel, alu angle and wood from a chopping board.

Nice build, meme! How did you fix side walls?


 

 

post #7464 of 9574

beautiful work meme! Are the wooden side panels glued onto the aluminium?

post #7465 of 9574

Thanks guys!

 

The wood sides are attached with 1/2" screws from inside through the steel brackets - just so if I get bored with them I can swap them for something else, e.g. darker wood.

So might as well show some of mine... think I never posted them on Head-Fi.

 

C3G headphone amp built in 2004, my first ever tube amp. I didn't know anything about tubes then,

and had to learn to read a schematic first... blink.gif

 

C3G-otl_5.jpg

 

 

Was based on s schematic from one Mr. Siemens (not THE Siemens) but changed to tube rectification

and the massive power supply. Flipped the switch and it worked... (wiping sweat off...).

Got me convinced that C3G triode wired is one fine tube...

Next was the Morgan-Jones headphone amplifier that was very popular on Headwize (too bad that the site is still down frown.gif ).

 

Was supposed to be much cheaper to build than the C3G to recover from the hole in my wallet wink.gif...

Also converted to tube rectification and later to LED bias in the first stage.

Was a nice sounding amp but never really convincing or "magic", the only amp I sold..
