Another K-12M Tube Amp

Since building a S-5 Electronics K-12M Tube Amplifier Kit, I have received several emails with questions and comments about this inexpensive tube amplifier. Well, Bruce has also built one of these popular and inexpensive Tube Amplifier Kits. In addition to finishing the simple kit, Bruce has completed a number of Modifications for the S-5 Electronics K-12M Tube Amp Kit. His modifications include many of VoltSecond's mods, new input and coupling caps, a beefed up power supply and upgraded output transformers wired in Ultra Linear (UL) Mode.


For more information and pictures of Bruce's experience with this kit, see his project page, More Modifications for the S-5 Electronics K-12M Tube Amplifier Kit.

For additional information about these and other inexpensive vacuum tube kits, see: S-5 Electronics K-8LS, K-12 and K-16 Tube Amplifier Kits.

DIY Audio Cables

New projects just added to the main website are a couple of simple DIY Audio Cable Projects.
The first project is a simple DIY Belden 83803 Mains Cable that I put together one evening. The mains cable consists of Belden 83803 wire, Marinco connectors and TechFlex for that nice audiophile finish.

The second DIY Cable project is Mark's simple recipe for DIY Silver Wire RCA Interconnect Cables. The design is very simple and requires only three pieces of insulated silver wire, heat shrink tubing and gold plated RCA connectors.
