===== Headphone and Mixer Mods =====

==== Kill Switch on Headphone Amplifier ====

The original [[TB-303]] had a kill switch hooked up to the LA 4140 (Headphone Amplifier), which makes sense, because the LA44140 is the only draw of the +6Volt power.

==== Modify Headphone Amplifier to Distortion Circuit ====

This is entirely theoretical, but you might be able to change the circuit so that the LA 4140 can be used as a Distortion, and/or EQ circuit. 

You'll need the [[http://pdf.alldatasheet.com/datasheet-pdf/view/40062/SANYO/LA4140.html|Datasheet]] If you are going to get far with it.
