Hi Guys
The LA-2A has the performance to live up to its hype.
The key to its effectiveness is the unique electroluminescent element that modulates the audio signal. It is one of those things that is now "obsolete" but has never been matched in what it could do. If you want one, I have one but it is not exactly cheap.
TUT2 shows schematics of Altec all-tube compressors and a simple one I devised. They are all relatively easy to make and do not use any rare or expensive parts. The LA-2A schemo is in there, too.
With bass, you can get some compression pretty easily from a dual triode just by cascading gain stages and adjusting levels to suit your instrument and your playing style. More stages make it easier, but you can do a lot with a little.
