Building A Tube Headphone Amp, A Learning Experience

I’m a music junkie – I’ll freely admit it. And I’ll also admit that I’m old school. I love listening on the couch, in a “sweet spot” perfectly situated between the two speakers. When I reached a point of owning my own house I was ready to invest in a decent way to play my music – and I quickly found out how much this could cost. However, I also discovered whole groups of folks online building their own equipment, experimenting and tweaking. I also discovered that this could cost a whole lot less! Being a tinkerer by nature, I was hooked, and by the time I was done I had built a tube preamplifier, solid state amplifier and speakers, tweaking parts and wringing the best sound out of components I had built myself.

Torx Screws, Torx Tools Available at KC Tool

A Brief Guide to Torx and Its (Many) Variations

­­We have discussed previously on this blog about the highly specific “Pentalobe” screw head and the tools used in conjunction. The Pentalobe shape is a relatively new invention compared to one its cousins, the Hexalobular screw, which many people call a star or Torx. Torx is actually a trademark of Camcar Textron, so the use of its name is another example of genericized trademark, like we use the term Allen Wrench for Hex Keys.Read More »

Ball-End Hex Tools: A Guide

Hex Key, Allen Wrench, L-Key, no matter what name you call it, if you have ever assembled anything you have probably used one. You can get them in Metric or SAE and they come in all kinds of sizes, from the tiny .028 inch to massive one inch. They are commonly used for furniture assembly because they are cheap to manufacture and can be tossed in the box for the customer to use (evidently they are like paperclips at IKEA and they will give you one if you ask nicely).

We have grown so accustomed to getting free L-keys in our furniture boxes that we take for granted the inferior quality of them and are very likely just to throw the tool away with the plastic bag it came in when we’re done. As any reader of this blog should know though, we buy good quality tools and demand only the best, so why use that freebie in the first place? A good set of L-keys will last you decades without showing wear and tear. But there is one big advantage to buying a quality set of L-keys and that’s the ball end.Read More »

What is a DIN number?

There are various sets of standards in the tool world.  In America we have The American National Standards Institute or ANSI for short.  On a global level, there is the International Organization for Standardization, or ISO.  Since this is a blog about specifically German made tools we will look at the German version: DIN.

DIN stands for Deutsches Institut Für Normung or German Institute for Standardization in English.  They have been operating for literally 100 years and have always been highly regarded in the standards community.  Though the name implies an exclusively German operation, the DIN standards have been adopted across the world and influenced many other standards organizations including the ISO.  The best example of this is the DIN standard 476 from 1922 introducing the A sizes of paper which would later become ISO 216 in 1975.Read More »

Red Bull Racing Tool Sets Made by Wera

Exciting news out of Wera this week.  They were proud to announce that they have partnered with Red Bull Racing.  They are one of the top teams in Formula One racing led by Daniel Ricciardo and Max Verstappen.  Red Bull Racing and Wera both have a record of branching out of their respective industries norms (i.e. Wera’s Advent Calendar, Wera Tool Rebels slogan, Red Bull’s Flugtag, New York Red Bulls MLS soccer team etc…) which makes this pairing so very cool.
