Beta Testing Amp #2 (Available)


Owned by a local audiophile friend, this amp was used as a beta testing mule for various circuit boards.   The only indication of this are extra mounting holes on the bottom of the chassis.
Currently installed is a Yuan-Jing "blue/black" TPA3116.  
This amp has an expensive, hand wired, Dale resistor ladder stepped attenuator.
WWII vintage panel meter that functions when the unit is powered up.
Premium gold plated Dayton Audio binding posts and gold plated RCA connectors.
Mahogany veneer on the top and a somewhat poor attempt at "engine turning" the aluminum.  
Please e-mail if interested.


Beta Testing Amp #1 with dual mono TPA3110D2 (Available)


This amplifier was owned by a local audiophile friend who "beta tests" some of the different amplifiers I build.  Since I'm always experimenting with new IC's and circuit boards, this amp has served as a test mule for several of those experiments.  The only indication of that are some extra holes in the bottom plate of the chassis, where different size circuit boards have been mounted.  We are retiring this chassis from beta testing and offering it to a fellow audiophile.  The amplifier is equipped with dual mono TPA3110D2 circuit boards, which are great sounding circuit boards.  If your system works well with SET amps, this will have about the same power as a 300B, if not a bit more.  The volume pot is a $100 TKD model that has one of the smoothest rotations of any I've used and sounds very transparent.   The panel meter on the front functions and indicates the input voltage from the external power supply.   Premium Dayton Audio satin nickel binding posts.

Harmonicat II TPA3110 (Sold to Mike D. of Washington D.C.)



There are audiophiles that share the opinion that the 3 watt TPA3110 is at the top of the ladder in terms of sound quality among the TPA series of amplifiers.  Many can't take advantage of the sonics of this amplifier due to it's low power output, but for those that only need one watt or two, the TPA3110 is preferred by some owners over multi-thousand dollar tube amplifiers due to it's ultra-quiet background, while still retaining triode like sonic qualities.
The above Fleawatt constructed amplifier has a TKD 2511 volume pot, solid core, teflon coated copper input wire and Kimber TCSS teflon insulated output wire.  The owner uses a 12V battery maintained by a battery tender.  This results in a very quiet background.
