Brook 10C3 Preamp

This preamp would have been used with the 10C or 12A Brook amplifiers. It has several 6SJ7 tubes. Constuction is interesting. I am glad the only thing wrong with it was a barely connected input wire in the umbillical cord. A quick easy fix.
I love the atomic style logo. Doesn't get better than atomic. 
 The different inputs allow for different gains. I'll need to consult the manual.
 Beautiful construction. Lots of parts in a small area.
 There wasn't much wrong with this unit as Modafferi worked on this in 1993.

Sound Technology 1500A Tape Recorder Test System Part II

This guy has been interesting. A computer of sorts from 1980. Removed all the boards and started replacing tantalum capacitors one by one. Once the big values were replaced each board came to life and finally the screen came on. The voltages also were correct.  Next step is calibration and try to pass the self test..

RIP Ric Ocasek

One of the coolest cats to walk the earth. The Cars certainly rounded out the 80's nicely.

Thanks for all the great tunes.

High-Quality Horn Loudspeaker Systems By Bjorn Kolbrek and Thomas Dunker

Thomas and Bjorn have just completed a major work on horn audio history. They have spent the last 14 or 15 years on this tome. I can't imagine the passion and dedication that went into this book. They literally spent years in research and writing. I hope to meet these gentlemen in person some day as it would be a priveledge.
They just annouced their website with information for the book. I am pleased to announce it will be available on amazon. I don't plug many things for money but please support their work by purchasing this book October 15th. Please reward their dedication and hardwork. Please buy a copy.

Sound Technologies ST1500A - Tape and LP Test System

Chris and have been working on this guy off and on for a while. There is finally light at the end of the tunnel.  Here is a pic of the ancient guts.

 With these boards removed we get all the correct voltages. Not so much when they are installed. I started replacing all the orange tantalum caps... Lots of caps.
This is what the input board does to the 1500A. Very sad. 

 Fortunately with the input board removed there are some signs of life.

 Can't belive how happy I was to see this boot up screen.. LOL.... Now back to replacing all the tantalum caps on that dam input board and hope it works.
