So my unit arrived. The preamp tube arrived shattered but thankfully I had a replacement 12ax7 for it anyways. So far it sounds pretty excellent. Much bigger and richer sound than the APPJ 2013. Definitely worth the buy.

Burning mine in now a couple days...thus far sounds even better than my Fatman hybrid tube amp ...plenty of power driving 92 db Paradigm Mini Monitor v6....But one of the feet is bent from shipping or whatever damage...have not tried to bend it back. There are certainly better looking amps but this one, I think, has the smallest form factor - I will be moving it to my kitchen where it should be a major improvement over my old Quinpu A6000mkII hybrid tube amp, driving very old but best sounding desktop speakers ever: Monsoon mm100 flat panels (not using the subwoofer/driver any longer). Anyway happy so far...my first class A fully tubed amp ever!

olneyleeI also added a supercube subwoofer (model 4000) so low bass is incredible. Also I have a little bluetooth receiver just to the right of the APPJ so I can stream from my cell phone. Kitchen homemaker heaven. The wife has not said a word...as I am the cook in the household...I would consider another APPJ for my desktop system at work, they are that good and inexpensive. Also - I rolled in 6CA7 tubes which are a bit less dynamic/groovy and a bit more extended highs/peaky. Either set of tubes (both EH) are very musical, overall I like EL34 a tad more...

How come there's no images for the output lines, are they standard 5-way binding posts?

None of my speakers sound very good at all until they have about 20-30 wpc.
Most bookshelves are rated at a floor of 20w, 4 or 8 ohms. Shit, my headphone amp even puts up good numbers compared to this.

Methinks you've not experienced a set of transducers with an efficiency rating of 102dB @ 2.83V / 1m.
That none of your "speakers sound very good at all until they have about 20-30 wpc." confirms VolvoSPeeV70R's comment that "you sir must have very very inefficient speakers."

I promised to update how Massdrop resolved my concerns. In a previous post I mentioned a problem that I had with the preamp socket. Massdrop offered me two resolutions. I could return the Appj and get a full refund, or I could keep the item and get a $50 partial refund. I choose the later. The amp works I just have to carefully insert the preamp tube at an angle. Now whether the socket will last a long time and sustain a lot of tube rolling is questionable.
Although the amp and tubes are still burning in, I like the sound quality, and it goes perfectly well with my speakers. My speakers are Zu Audio Dirty Weekend with Druid drivers. They are 16 ohm 101 db speakers designed to be combined with tubes, so the amp powers them to concert levels if desired.
I replaced the tubes with Tung-Sol EL34 and 12ax7, which is a huge improvement over the stock tubes especially the preamp tube.
Overall, I'm happy with Massdrop's resolution. I thought people would want to know about this, especially since there were questions about how reliable Massdrop is about warranty issues and so on.

robb37Thank you for the detailed follow-up, the partial refund is an interesting solution!

Has anyone else had quality control issues with this amp? My came with the preamp slot sunk into the amp at an angle. You have to carefully insert the tube. If you don't it will not play or only play one channel. If you are careful enough it will take the preamp tube, but it's not stable. I've complained to Massdrop because that's how it arrived. We will see what Massdrop does about it.

Mine came in with that issue as well, along with the transformer cover being smashed on one side. I am wondering if APPJ just unloaded a bunch of scratch-and-dent units through massdrop. The shipping box didn't show any signs of damage.

I received my amp last week. Don't understand why Massdrop put the excellent box from APPJ into another box twice its size with little packing so it could slide from one end to the other the entire route!! Luckily it was in one piece. This is a well built product, APPJ is on a roll. Much fuller sound than my Miniwatt 2013, this amp put a huge smile on my face. The included EH el34's are excellent, in fact sounded better than the tung-sol's I tried, and the EH 6CA7's as well! The included preamp tube is crap, and you'll get much improvement with a 12ax7. I am using a tung-sol reissue and that's my favorite, with the the Sovtek 12ax7lps close behind. Lot's of fun, highly recommended!!

How does this compare with Monoprice's new Pure Tube? https://www.monoprice.com/product?p_id=27222

Alejandro508A quick look on eBay for a NOS pragmatic price/sq deal, but still a very nice set of tubes, i.e. what I would like to buy today, and want to relax and listen with over the holidays:
Reading about it, almost bought it... 'Well tempered Lab, needs good home, to curl up in front of a fire.' https://www.ebay.com/itm/SUPERB-1963-YELLOW-MULLARD-ECC83-12AX7-COPPER-POSTS-AVO-TEST-AS-NOS-122-128/253322878774?hash=item3afb385f36:g:Vr8AAOSwiYlaOx7k

I am new to Massdrop and am looking for help. I got my amp 1-1/2 weeks ago and it has not worked since day 1. The amp produces a hum followed by a clicking noise about every 2 seconds through the right speaker. No other sound comes out from the speakers. The tubes do not glow nor get warm. I tried replacing the 6N4 with a new 12AX7 and replacing the EL34s one at a time with a new EL34. Same problem persists. Has anyone encountered this problem before? How can this be fixed? How can I contact APPJ to get help?

LOL ... loud enough to cause hearing damage from sustained listening.
Be careful with your ears good sir!

LiquidSmoteI can't do it sustained. I'm old. But I like to for one, or two songs. I actually just put together a real nice system for this reason only with an AVA Omega Star 250EX, and a pair of Cerwin Vega VS-150's. Love to pound the rock, and this does that very well. It's unbelievably loud!
