Description

Often referred to as a “Blue Stripe”. These units were the first commercial revision and have a silver panel with a distinctive blue stripe over the VU meter. The signal and line amp are based on the 1108 mic pre and use a FET as the first active component in each amp stage (all other revisions use a bipolar transistor). The gain reduction FET in this model has a unique circuitry around it, different from all other models (notably the lack of source resistor). This results in a little more distortion that helps define the “Blue Stripe” sound. This revision also has a slightly lower threshold in comparison to later revisions (about 5db) and more gain in the amplification stages (about 5db) than the Rev D. This revision is rare, limited to less than a 1000 units, and are highly sought after by many engineers and producers.

Electrical interference only when using dynamic mics

...not attempted shorting the pins together as you described, but I did replace the mic with the output of a Hairball 1176 Rev A That I built to see if the xformer would help, which it did. I’ll see what shorting them together accomplishes. The low voltage service pole is indeed grounded deep underground (in...
