Hello all, I am selling my beautifully maintained vintage LA2A as I am not using this in stereo as I thought I might and one unit it enough for me. This is unit #1660 which is the Silverface Revision 2C line.

The unit has been lovingly cared for and lived in a rack up until moments ago. It's been professionally maintained and works beautifully.

It has the A24 output and A10 input transformers. Works perfect and unlike earlier models of LA2A it does limiting and compression so you can do that 1176 in limit and LA2A in compression effect or switch to the original limiter effect. This has the T4b opto which is faster than the T4a but they are easy to swap out depending on the type of inputs you are working with.

Please serious buyers only. I will ship anywhere but the displayed rate covers US only with full insurance on the value. I do not ship without insurance.

Here is some history on this unit and LA-2A's for reference:

The Teletronix LA-2A Leveling Amplifier has a long history stretching back over half a century. During that time the company changed hands and the model went through a variety of incarnations. Despite these several changes, the LA-2A has remained one of the most popular tools in the recording studio, beloved by engineers for its program-dependent compression and ease of use. Beautiful for vocals, bass, guitars, overheads, drums, etc.

Essentially there are six different versions of the LA-2A, based on various design elements, parts, outward appearance, and parent companies. The six revisions can best be classified as: Revision 1 (the original); Revisions 2A, 2B and 2C (all inter-related in various ways); Reissue 1 and Reissue 2. The first four versions kept consecutive serial numbers, while the two reissues had their own numbering scheme.

The final, seventh version, appeared when Universal Audio was resurrected by Bill Putnam Jr., and the LA-2A made its modern reappearance in the line of "UA Classics".

Briefly the differences are most easily classified by company ownership:
 

• Revision 1 - the original, produced in 1962 by Teletronix under Jim Lawrence, inventor of the LA-2A.
• Revision 2A - Teletronix patent is acquired by Babcock Electronics
• Revision 2B - Teletronix patent is licensed from Babcock Electronics by Bill Putnam Sr. / Studio Electronics
• Revision 2C - Teletronix patent is acquired from Babcock Electronics by Bill Putnam Sr. / UREI
• Reissue 1 - 1979 reissue by UREI / United Recording Electronics Industries
• Reissue 2 - 1992 reissue after UREI is acquired by Harman Electronics / JBL
