Mike, thanks for the link. Now I don't feel bad about my PA300 for my '86 FHP. It is good for use.

Mid to late 1980s: PA300, PA500, PA2100, Minicom remote sirens
Suitable for restoration of emergency vehicles built from 1984 to 1990.
Early PA300.
Up until the mid 1980s, Federal made sirens with analog circuitry, which used transistors to generate the siren tones. Since the introduction of the PA300, newer Federal electronic sirens use integrated circuits (ICs) to produce the siren tones. With the PA300 came a new tone - the 'air horn' sound. From a distance the early PA300 resembles the PA150 and PA200, and for a brief period all three models were in production at the same time.

No prob, Marcos.

Is yours a silver-faced PA300?

No, I have the black face.

He lists the black face as 1990-present. While that's just an estimate, I'd say it's pretty close. For your '86, I'd try to find a silver-faced PA300 or go with a PA200 (or Whelen WS295).
