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.

A bit of amp blueprinting from the past

I was going through some records on some customers amps from the past.  I came across one blueprinting session that was a little different than most as these were preamps which contained eight tubes.  There were also multiple units that were very different as the model had changed in revision levels over it's production life. 

I thought that going over some of the data would shed a little light on some of the process of blueprinting and some of the ways that tubes are very inconsistent.

Bogner Fish Preamp - 8 12AX7 tubes.
