Dirty Girl 5879 Model Head Ocean Turquosie Mettalic
Here's a really cool amp from Dirty Girl which made great Supro style amps. This head is in great condition.
As per Dirty Girl:
The Dirty Girl '5879’ is an amp which pushes the limits - in a very good way - of what can be accomplished by carefully ‘melding’ various aspects of the familiar Valco circuits. This amp is somewhat of a blending of the late 6973-based Supro Supreme, the Supro 1620T and some of the earlier Valco circuits (i.e. the Supro Brentwood, National Aztec etc.) which featured the wonderful 5879 pentode. This tube is a small nine-pin tube which at first glance may resemble the familiar 12AX7, however it is an entirely different animal. I use the 5879 as the input tube for Channel 1 on these amps and it very definitely offers a more expansive, three-dimensional sound when compared to the same circuit more commonly built with a 12AX7. While these tubes, like most input pentodes, can be prone to some microphonic issues, I take great pains to carefully tailor the circuit to preclude such problems as well as shock-mounting the tube socket itself so as to render most 5879 tubes just as quiet as the best 12AX7. An added benefit is that n.o.s. 5879 tubes are both plentiful as well as fairly inexpensive!
Compared to a Dirty Girl 'Heavy Hindenburg' (1624T), this amp has a small amount of increased headroom as well as an increase in treble content; it is definitely a brighter amp with an excellent degree of clarity when driven, despite retaining much of the ‘trashy’ Valco DNA. Possessive of a noticeable top-end sheen/shimmer, it’s been noted that ‘The 5879’ seems to evince some passing characteristics of the smaller Vox and Selmer amps when paired with a British-voiced speaker.
