Miscellaneous Headphone Amps
Will Ship To: lower 48/USA
I have moved on to mostly speaker listening and I have several headphone amps for sale.
PPX3 SLAM ... 6SN7 input / 5687 outputs. A 6CG7 to 6SN7 adapter will be included for the input stage. Tung Sol black plate 5687's for the outputs. The amp was built early 2007. I have 7044 and 7119 output tubes that sub for 5687's as well. I like the Amperex 7119 and TS D getter 5687's best. $325 plus shipping
MPX3 .... this is a special version that has the power inlet to use 6.3 or 12.6 volt tubes. This amp is probably my favorite of the two because I can roll tubes endlessly. Currently, I am just running the amp at 6.3 volts and using adapters for a 7N7>>> 6GU7 X 2 combo. Bu you can use 6SN7/12SN7, 7N7/14N7 with adapters, 6CG7/6GU7 with adapters and I have 5687 adapters wired to use only at 12.6 volts. I have had this amp since late 2006. $475 plus shipping
Both the Singlepower amps are dead quiet, have worked flawlessly over the years and have never needed any kind of repair. If you want extra tubes I have anything you can think of. I am selling these amps because I have factory boxes for shipping. I still have a PPX3-6CG7 and a Supra toaster style from 2003 and a heavily $$$ upgraded Doge 6210. I know that I would never get close to the money back I put into the Doge .... so I think I am keeping that headphone amp too????
Cavelli Audio hybrid. 12AU7 front end X 2 with MOSFET output. The amp has a separate power supply connected by an umbilical. This amp is very, very good with Grados and other low impedance headphones. $150 plus shipping
Sound Quest SQ-84 10 watt 6V6 Integrated amp/ headphone amp. The headphone output is not transformer coupled despite what was claimed. The headphone section is cap coupled and works ok with Grados but better with high impedance Senns etc... IMO. The SQ-84 uses 6U8 x 2 and 6V6 X 4. $425 plus shipping. This amp is a really good speaker amp too. I got his in a trade for an Extreme and I am the third owner.
Now, my digital camera is broken so I don't have pics of all the amps. Here is what I have ...
The Cavelli looks like the amp at the top right but has a black top vs the silver top of the amp shown. Yes I am a headphone addict and all the hybrid amps in the picture have been sold except for this Cavelli .... which I kept because it was my favorite.
I am open to some negotiation for partial trades .... cd players or tubes. Low ball offers will be ignored. As mentioned I have a large tube collection and if you want any extra or different tubes I can sell you what you want and I am reasonable price-wise.
If anyone is in the market for an excellent 8 watt integrated speaker amp this will be for sale too ....
