Hairball the Black Face Rev D -1176-FET Compressor

This is a brand new hand-wired Hairball 1176 – FET – REV D compressor.

This revision covers the REV B thru E units. Most current reissues are based on this revision. Revisions C-E had a black front panel while the Rev B retained the silver and blue stripe panel. Changes were made to the stage and line amps so a bipolar transistor was used as the first active component. Low noise, or “LN” circuitry, was added to this and all future revisions. Like the Revision A, the input uses an O-12 transformer and the signal is attenuated at the input with a 600Ω T-pad. The output is class A, utilizing a 5002 output transformer. This is widely considered to be the most classic FET compressor sound.

Passive and active link both have their advantages. The advantages of using active link include:

1. unlike passive link, attack times are not doubled when using an active link
2. does not require an external adaptor or calibration
3. activate linking with the push of a button
4. links easily to Purple Audio MC77
