6SQ7 EL34 Tube Audio Amplifier: Output Tube Voltage Test

Warning: Voltage testing a tube amp is dangerous. In this video we power up the amp and check the internal voltages. I cover a few safety tips, you can see more here.

Here is a link to the tube bias calculator I like:

and here is a basic Ohms Law calculator:

This is a replicate of my personal favorite, a 6SQ7-EL34 amp with modifications to make it more "public friendly". This series will document the build in detail, explain all the design considerations, dig into tube data sheets and other criteria that makes this little amp sound so amazing!

I'll get the schematics and BOM up on the website this week as I start on the actual build series.
