Fleawatt Hod-Rodded Dayton B652 Air (Sold)

The Dayton Audio B652 speaker was a fantastic budget audio speaker.
The B652 Air took it for a giant leap forward.  
My hot-rodded version includes the following modifications:
Stock electrolytic capacitor replaced with an audiophile quality Jantzen cross-cap.
Stock resistor replaced with a Mills audiophile resistor.
Stock fiber replaced with Acousta-Stuff fiber made for speaker enclosures.
Stock sponge feet replaced with 3M brand elastomer isolators.
Deeper bass and smoother midrange over the stock B652 Air.

Hot-Rodded Klipsch KLF-20 (Fleawatt Modified)

I love the Klipsch KLF series.  I've wanted to acquire a pair and modify them with new baltic birch cabinets.  In December, I found a pair of KLF-20's that were the perfect candidates.  New 1" thick baltic birch top, bottom and side panels were constructed.  The crossovers were re-capped with Dayton Audio 1% precision poly caps.  The tweeters were upgraded to Bob Crites Titanium.  

"Fixed Gear Tribute" TPA3116D2 (Sold to Alex B. of St. Louis, MO)

This amplifier is my tribute to fixed gear bicycles. (one gear on the faceplate)  A fixed gear bicycle has only one gear and it is directly tied to the rear wheel hub, with no freewheel.  Used by track cyclist, professional cyclists for training, bike messengers and hipsters, it became a prominent subculture of cycling.   
This amplifier has an upgraded "Audiobah" TPA3116D2 circuit board.   Some fans of the popular TPA3116 amplifier prefer this circuit board over the YJ "blue/black".   Preferences would be purely subjective and system dependent as I think both sound fantastic.  The stock power capacitors were replaced with 35V 1000uf Nichicon Fine Gold capacitors.   A Vishay 1% SMD resistor stepped attenuator performs the volume control duty.
Real brass accents adorn the black textured die cast aluminum chassis.
Comments from Alex:

"I love the amp! I have owned all kinds of high end solid state, push pull tubes and SET and this amp is right up there with the best of them. I have tubes that cost more than your whole amp and it is top notch."

"Naked Diecast" TPA3116D2 (Sold)

The amplifier circuit board is the Yuan Jing "blue/black" TPA3116D2.  Equipped with a multimeter inspected, high tolerance, Alpha 100K volume control.   Solid metal, gold plated five way binding posts.  Gold plated RCA connectors.  A very quiet, external 12V/5A switching power supply provides power for 15 watts per channel into 8 ohms.  An optional 24 volt supply for 30 watts is available. 

Vertical Bi-Amp 3116D2 (Sold)

This amplifier is made for bi-amping speakers that have bi-wireable passive crossovers. 
One pair of binding posts connect to the low posts and the other pair to the high level posts. 
Dual TPA3116D2 amplifiers handle the power and are handed off the audio signal by a Teradak brand Vishay precision resistor stepped attenuator volume control.   There are only two 1% tolerance Vishay resistors in the signal path before hitting the circuit board.  The amp is wired with plenum grade Cat5e (teflon insulated) & shielded copper cable.  Solid brass, vintage look toggle style power switches, gold plated, solid metal binding posts, gold plated RCA's, 3M elastomer vibration isolation pads and a textured black enamel round out the aesthetics.  Individual power supplies can be used for each section or a single, 10amp or better single supply with two power cord leads.  

"Alpha Aluminum" (Sold to Caintuck Open Baffle Speaker Co.)

Equipped with the blue/black Yuan Jing board.  Alpha brand volume pot that is tested with a tolerance of 1% between channels.  Plenum grade Cat 5e signal wiring.  
Includes a 12V/5A power supply.  Wondering what's up with the screw heads on the top of the amp?  I mount the board to the top to facilitate the shortest wiring paths possible.  Mounting on the bottom plate looks nicer, but I'm about the sound.

"Henry Ford Model T" TPA3116D2 (Sold to Caintuck Open Baffle Speaker Company)

"You can get it in any color, as long as it is black."  

Many of the inquiries I get are from audiophiles asking what is the least expensive, while still sounding good, amplifier that I can build.  Well, here it is.  A good portion of one of my simple amplifiers costs is the volume control & aluminum chassis.  When I first started building amplifiers, I used the inexpensive Alpha brand volume pot.  This is a carbon track potentiometer.  Music reproduction is a matter of taste, but I could imagine some audiophiles, who enjoy a warmer presentation, may even prefer this volume pot over a more open and revealing Vishay stepped attenuator I use.   Unfortunately, the channel matching on these Alpha pots is inconsistent, as it can be with less expensive volume controls.  Never fear though, the flea measures each channel and promptly throws any in the garbage that have more than 1% difference between channels.  This ends up being about 25% of them.  Why is channel matching important?  Imaging and the centering of the performer in the soundstage.  (when recorded that way)
I tried less expensive plastic boxes to house my amps, but I just couldn't come to terms with the low quality look, light weight & lack of RFI & EMI shielding of the die cast aluminum boxes. 

Other features of the basic "Model T" include gold plated RCA's, five way binding posts, neoprene circuit board mounts, 3M elastomer chassis vibration isolators, teflon insulated solid core copper wire, along with shielded copper & a retro look power switch.  A 12V 5A external power supply is included, unless you would like to provide your own.  

"Antenna Current" TPA3116D2 (Sold to Tom H. of Salt Lake City, Utah)

Features include the YJ "blue/black" TPA3116D2 circuit board with Nichicon power supply capacitors.  Measured .5 ohm tolerance left to right YJ volume pot.  A vintage Weston antenna current indicator panel meter sweeps to #2 on power up, with 12 Volts.
15 watts per channel into 8 ohms with the included power supply.

"Walnut & 24ct." TPA3116D2 (Sold to Josh R. of Louisville, KY)

This amplifier is equipped with the "Danzz" designed TPA3116D2.  An Alpha volume potentiometer, premium gold plated binding posts, real walnut veneer top, solid brass vintage look power switch, gold plated RCA connectors & 24ct. gold leafing enamel pin striping round out the rest of the amp.  A 12V/5A external power supply is included which will elicit a solid, gloriously robust, smooth, 15 watts per channel. $185

"The Ninja" TPA3116D2 (Sold to George in Richland, Washington)

This stealthy black beauty is equipped with the Valab Vishay precision resistor stepped attenuator & twisted solid core copper signal wiring.  Simple, elegant, beautiful sound.  

JDS Labs ODAC DAC (Sold)

I'm a fan of the JDS Labs ODAC.  It's inexpensive and sounds super.  There has been a lot written about the ODAC and there are many happy owners.  I do dislike the very small cases many USB DACS are packaged in, including the stock ODAC.  I took the liberty to mount an ODAC circuit board in a larger enclosure and wire her up with some VALAB brand, teflon insulated, silver plated copper wire.  Gold plated RCA connectors for the outputs.  $159 includes the stock JDS Labs USB cord.

Rt. 66 Tribute TPA3116D2 (Sold to Kevin K. in Costa Mesa, California)

U.S. Rt. 66 was one of the original highways within the U.S. Highway system. Route 66 was established on November 11, 1926—with road signs erected the following year. The highway, which became one of the most famous roads in America, originally ran from Chicago to Santa Monica, California.
Route 66 served as a major path for those who migrated west, especially during the Dust Bowl of the 1930s, and it supported the economies of the communities through which the road passed. People doing business along the route became prosperous due to the growing popularity of the highway, and those same people later fought to keep the highway alive in the face of the growing threat of being bypassed by the new Interstate Highway System.
This unique, one of a kind piece of audio art  is equipped with the very popular Yuan Jing blue/black TPA3116D2 circuit board.  This might be one of the only audiophile amplifiers to have a keyed on/off switch.  An extra key for under the floor mat is included.  The volume pot is the very transparent Teradak stepped attenuator.  Teflon coated solid copper signal wiring.  The paint is a textured black with a chrome plated, solid brass volume shifter knob.  Not only is this amplifier a one of a kind conversation piece, it sounds finely tuned & should transport you to audio nirvana.  Comes with a 12 volt/5 amp power supply that will allow the amplifier to accelerate to 15 watts per channel into an 8 ohm load.

Espresso & Brass (Sold to Wesley T. of Statesville, North Carolina)

Equipped with the YJ blue/black TPA3116D2 & a very transparent sounding 100K Teradak stepped attenuator.  Espresso brown & brass accents.  24K gold pinstripe.

Antique Copper 3116 (Sold to Joe S. in El Paso, Texas)

I experimented with a painting & weathering technique to give this amp an old, worn out look.  I'm not satisfied with the outcome.  The amp uses the "blue/black" circuit board that everyone is drooling over.  Rather than scrapping it, I'm offering this amp at less than parts cost.  Uses shielded input wiring and a YJ volume pot.  (sounds eerily similar to the Alps blue velvet)  Includes a 12V 5A power supply.

"Hammered" TPA3226 with Alps Blue Velvet (Sold to Scott in Tarzana, California)

A vintage look giving a nod of admiration to the classic hammertone gray Garrard 301 turntable.  Yuan Jing "blue-black" board mounted on neoprene isolation pads.  Alps Blue Velvet volume pot & a rotating on/off switch.  (on left)
