sold
For sale is a Mark Johnson designed Ship of Theseus modular amplifier using all his board designs. While based on the VFET Pass amps, this amp uses Mosfets for output devices only and sounds quite nice. It puts out about 10 watts per channel into 8 ohms.
Housed in a standard 10mm silver faced 4U x 300 dissipante chassis, the amp gets Class A warm, but not hot, to the touch.
It is powered by the called out Meanwell external 4.4 amp supply, which is smoothed by the Ship of Theseus PS Filter board with variable time delay for thump prevention. This amp is totally quiet on my 96db sensitive speakers with either front end cards installed.
Two different front end card systems are included: The Missouri cards can take balanced inputs, which is a great option in my book, and seems to make the noise background even blacker, to me.
The other front end provided is the Nimitz front end, which allows the owner to use any of the M2X input cards designed by Mark, and maybe even others. Check out the M2X thread for those details. I have included a pair of Cedarburg front end cards using the wonderful AD797 opamp. That was my favourite in the M2X and it sounds great in this amp also. I have included a pair of bare IPS-7 boards you can build up and use if you wish, also.
This is a single ended input front end, so I have included rca to xlr adapters with the amp.
I can set this up with the Nimitz or Missouri front end for the new owner. You should feel comfortable with DIY if you plan to change things around or make up other front ends or M2X cards.
Overall, this is a great little amp with wonderful frequency extension and bass impact for its 10 watts. It has numerous other front end combos that one can experiment with, if you wish.
Amp and power supply are about 32 pounds, I will ship to the Continental USA only via insured ground shipping. Shipping to be determined at time of sale. You will need to supply a basic power cord for the Meanwell.
