This is the 500 series version of the Silverface and it sound identical to the Revision F rack version Red Stripe.<\/p>\n
This unit was offered in a black panel and a silver front panel similar to the Revision A but without a blue stripe. The major change to the revision F was the redesign of the output stage from class A to a 1109 style class AB \u201cpush\/pull\u201d output, utilizing a B11148 output transformer to provide more gain. Like the Rev A and D the input uses an O-12 transformer and the signal is attenuated at the input with a 600\u03a9 T-pad. We believe the Revisions F is highly underrated and when given a 2:1 ratio becomes one of the more usable compressors we\u2019ve heard. In many cases, original units are confused for Rev C\/D\/E’s with engineers mistakenly\u00a0thinking of the revision F as a silver faced unit.<\/p>\n
