Case not included. Axial caps are substituted in

1. The case is not included as others have stated. And if we are honest with ourselves the price indicates this but the listing is very deceptive. The good pare is that the case for this is generic and easily obtained for $10. Which puts this kit with case at $25 which is comparable to the others.2. I have other versions of this kit. And this particular version has an huge flaw. Axial caps have been substituted in for the correct non polar caps, and stand too tall to fit in the generic case sold for these units. I happened to have a case for these on hand so I used it for this build. In order to get the board in the case, mods were necessary. I coated the exposed axial lead ends with solder mask and drilled the case to make room for the leads. I used some tale to cover the drill holes and some UV resin to seal off the top surface of the holes to close off access to the conductor. That’s a lot of work and cost if someone doesn’t own the mask, resin, UV light, and tools require to make the modifications.I wouldn’t recommend this particular version of this amp for a beginner. I think the issues would be very discouraging. Not getting a case you think will be with it then having to mod the case. No bueño! These kits are supposed to be fun. So look at a different version of this kit and have fun.I’ve noticed others mention no instructions are included. The board is labeled with all values and orientation very clearly. Some basic understanding of how to tell which lead is + or - can be googled to figure that out if you don’t know already.I also noticed that plug polarity is mentioned nowhere. The jack is center hot. 12VAC NOT VDC

Case being included is a lie

This kit for the most part is very good. I comes with the yellow poly caps most other kits do not. The electrolytics are low esr and appear to be of decent quality. The biggest disappointment is it did not include the acrylic case. It shows it in the product photos and states in the description that it is included. I believe this to all be false advertising as im not the only one to not receive the case.

Decent sounding unit but lots of hum

Building this took some work and you really need to know which parts to solder where on the board. It's not rocket science but it's also not for beginners. And one channel has a lot of hum (L channel signal trace goes right next to the AC heater circuit). There's a website with suggestions about a fix, but it's a tricky fix. The simple little unit isn't bad and has a ton of gain (that's why I bought it so it works for me) which may not work for you. Also, the supplied tubes are mis-matched (one heater runs at a much higher level than the other, and may be the cause of the hum). If I did it again I'd probably look for the schematic and work on improving implementation (e.g. wiring routing, etc.).

Pretty easy to build

Pretty Useless

This preamp kit arrived in the mail as a bag of parts and a circuit board. There was no plastic case included. I was astonished that they packed a pair of fragile vacuum tubes in a little bit of foam wrap and a flimsy plastic bag. There were no instructions or schematic. An experienced builder can puzzle out the locations of the parts using the board layout, a volt-ohm meter, and online photos of the completed board. The resulting product was completely underwhelming and disappointing. There is so much hum in the circuit that turning up the volume results in more hum than music. It’s a totally useless, defective design. Avoid!

No case included

There was no case included. I specifically ordered this version in order to get a case.

Does not include the case

Although prominently grated in the images of this product, the case is not included. Otherwise nice little kit, easy to assemble.

Parts damaged and missing, TWICE!

Contents did not match description, tubes have bent pins from being in a plastic bag, then shipped in a plastic bag. Twice now.
