A PCL86 SET kit with chassis from the DIY Audio Store

The DIY Audio Store (part of the diyaudio.com forums) is now selling the Elekit TU-8100 PCL86 kit:

At only $275, this 2W output kit is about as low an entry point to all-in-one well-documented tube kits as you’re likely to find. It includes two inputs (rear and 1/8″ front) and is powered by a 12Vdc power brick. This keeps the amp small enough for even desktop usage (5.5″ square). According to the ad copy, SMD components (DC booster, etc) come pre-soldered.

The PCL86 is a 9 pin triode + pentode roughly equivalent to a 12AX7 and EL84 in a single envelope. See a datasheet here. It’s used in the Elekit in a traditional two stage cap-coupled single-ended arrangement. The output transformers are rated as a 7k primary and the circuit employs global feedback to squeeze some extra linearity out of the high gain input stage. See the Mighty Cacahuate for a similar design (no feedback and 6CG7 instead of 12AX7).

If you’re hoping to find a tube kit under the tree this year, add this one to your Christmas list. Elekit puts out some very cool products and purchasing through DIY Audio Store helps support one of our hobby’s precious resources.

I have no affiliation with Elekit or DIY Audio (other than sincere admiration).
