Ampeg Portaflex PF-50T Head

Bass amplifier / top
The PF-50T top delivers Ampeg's classic R&B sound in a compact package. The top fits perfectly with the Portaflex cabinets and is suitable for use at small to medium-sized concerts, in the studio or in the rehearsal room. Together with the compact PF-112HLF cabinet you get the typical Ampeg sound for on the road. 
The amp has been developed mainly for ambitious studio use. A special feature is that it can be operated without a load resistor, i.e. connected speakers, as a kind of high-quality Röhren-D.I.. The amp produces a warm, clear, mid-range sound with two 12AX7s in the preamp and two 6V6s and a 12AU7 in the power amp, which can be further shaped using the three-band tone control. With the rear bias control you can adjust the operating point of the speakers, which also allows for different sound colours between clear and transparent as well as fat and powerful. Of course, a higher load on the speakers also reduces their durability, which should always be kept in mind.
Ideal for studio use are the two D.I. outputs (balanced out and preamp out); so you have different options available when you want to tap the signal and send it to the mixing console, for example. Even on smaller Bühnen the small one can hold its own, because 50 watts of Röhrenpower are clearly more powerful than 50 watts from a transistor or digital amplifier.
