Review: Great amp, best sound i have heard for under a grand. - Honestly this is my first stereo tube amp, as a guitar player i have played many many tube amps vs solid state. So in that capacity i have always preferred tube to SS. At 3.5 watts i was skeptical at how this would shine. My current amp, before this one, was i an Akai AA-1175 from 1978. It is a true gem as solid state goes. 75 watt dual mono amp and one of the best sounding amps that i have ever listened to. I am not going to argue that its the best amp out there, but its a good one. But hands down this little tube amps sounds better, even the wife can hear the difference. While no where near as loud as the Akai, it sounds better and its loud enough to fill up my living room with sound. The bass is tight, mids are smooth and treble has a bell like tonal quality. I love this little amp enough to put my solid state in the closet. I have listened to it for about 4 hours now and everything i throw at it sounds amazing. I have done pop, rock, jazz, rap, country i mean i really put it through its paces. But to be fair i am running a pair of infinity overture 1 bookshelf speakers, which have an 8 inch powered sub. So bass may not be as strong with a non powered speaker, but i did have to turn the bass knob on the speaker down because the bass was to heavy. Over all i am very happy with this amp, i mean i love it. For 210 bucks its a great amp. For the guy that says it gets to hot, i dont see that at all. I mean its a tube amp so the tubes get hot, but its not gonna heat up room or anything.
Review: Twin Tube Appj PA 1501A Throws Too Much Heat, I Prefer the Three-Tube APPJ PA0901A - After using the APPJ PA0901A (the three tube model) for several months, I purchased this newer twin tube model for a second location. The older three tube PA0901A is excellent and runs warm to the touch. The transformer tops are about 98-103 degrees fahrenheit after several hours. The new twin tube APPJ PA1501A sounds and looks great, but it gives off much more heat. The twin tubes run very hot and the metal chassis heats to about 112-118 degrees. It is too hot for my desk. I returned it for the three tube model.

## Questions & Answers

**Q: What type of power cable do I need for this. Where do I get it**
A: It is just a standard 3 pronged cord and I just used one from an old piece of computer equipment.  You can buy them at Best Buy and other places if you don't have one laying around.

**Q: Can I use this amp with regular speakers or is for headphones?**
A: This amp is designed for speakers and works even better with a pre-amp.  Banana plug connectors are required to hook up the speakers. I believe they chose this design as vacuum tubes and their circuits need to be under load while the amp is powered on to avoid burning them out prematurely.

### ⭐⭐⭐ Fun amp, but you may never be able to find suitable replacement tubes
*by C***S on August 9, 2016*

I'm enjoying this for a first tube amp. The sound is definitely bright and trebley on large speakers, but it sounds pretty nice with my Klipsch Heresy KP-201s. It pushes to higher levels than you'd expect before distorting very badly. It also likes to be driven with a tube amp, it hit distortion a lot faster when I had my DAC plugged right into it. Build quality is nice, too. The case feels solid to the touch and it's nice and heavy. The volume knob and switch, the two most common points of contact, both feel pretty nice. It's surprising what they could do for $200. The use of 6AD10 tubes is pretty cool, but not very useful. It's a tube design that was come up with in order to simplify tube electronics back in the day, it does the job of multiple tubes in one big fat tube. But it doesn't seem that they're made anymore, and there isn't much information out there about whether any suitable equivalents exist. I would have bought the three-tube one if I'd known that, it seems like its tubes are much easier to find. I'm enjoying it for now, but I do wonder what will happen when the tubes need replacing.
