The [Hardrock-50](https://www.hobbypcb.com/index.php/products/hf-radio/hardrock-50-hf-power-amp) is a very nice 50W short wave amplifier that comes as a kit. The package includes everything needed for building the amp. There were some optional modules available (QSK Mezzanine add-on board and an automatic ATU) which I decided not to order since I am very happy with my [ATU-100](/atu-100/). The Hardrock-50 includes an interface to some rigs including my FT-817 which allows automatic band selection. For this, nn additional but easily buildable Sub-D to Mini DIN cable is needed. Shipping of the kit to DL was fast but quite expensive.

The kit includes the enclosure, 3 PCBs, all necessary hardware, cables etc. A manual is not included but can be found on [here](https://sites.google.com/site/hardrock50beta/hardrock-50-builders-information-site/hardrock-50-builders-portals/sn1400-and-up-builders-portal). The manual is the most detailed guide i've ever seen for a kit.
