A little more information

The two main activities in my life: Helping the hungry in the late hours of the night and helping guitar players sound better one amp at a time.

I always try to remember that in order to do good one has to take action and actually do something.

I was born and raised in Los Angeles. I have watched the city and Southern California change for well over half a century.

As of late 2019 the music related links and prints noted on this page which had their links to by GAB (Guitar Amplifier Blueprinting) website are no longer accessible. I grew weary of updating my GAB website and let it go away. You can contact me on Facebook. Saunders Stewart Models continues full operation but we are not accepting new clients without a referral.

Current Production 12AX7 Tubes

I have been promising a current test of some of the current production 12AX7 / ECC83 offerings and have just completed my testing.

Gain and Transconductance. Some folks confuse these two things. Maybe this will help explain:

Gain is the factor by which an amplifier multiplies a signal. It is the product of the output voltage at the plate divided by the input voltage at the control grid. Gain is a unit-less factor since both measured signals are voltages. (voltage)

Transconductance is a measurement of the ability of a tube to transmit current. It is the product of the output current in amps divided by the input voltage at the control grid. Transconductance is significant in that it shows us the difference in current capability that is generated by variations in plate impedance between tubes. (Current)

When I test tubes I also measure standing plate emissions current for preamp tubes that will be used in the phase inverter position. Plate current is one factor that many tube testers do not measure.


150 tubes were tested. 15 of each type.  The above lines on each tube are the average of that particular tube.

Los Angeles - Highest Homeless Population in the U.S.

This is the April 2013 update from Union Rescue Mission.

I have written about URM and Andy Bales their CEO since 2009.  Some of my other pieces can be found here:

You can help.

Update today 5/8/13.  I posted this on facebook:

Congratulations to the folks at Union Rescue Mission and their CEO Andy Bales and their VP Jacqui Groseth. The latest facts and figures are in from Charity Navigator, the folks that investigate and rate all the charities. URM received 4 stars out of 4 for Accountability & Transparency. A score of 67 out of 70. 

Back in 2009 I wanted to align myself with one of the homeless support organizations in Los Angeles. I spent a lot of time visiting facilities and asking questions. In the end I picked URM. Looks like I made a good call.

In the end there are many great organizations in Los Angeles but it makes me smile when I look at these independent reports and find that URM came out ahead of the two other Los Angeles missions that I also feel do great work.
