Ampeg Introduces All-Tube Portaflex Bass Amps, 1×12 Cabinet

Ampeg Portaflex Series

In 2011, Ampeg launched the Portaflex Amp Series featuring solid-state preamps inspired by their iconic B-15 amp. Now the company has expanded the line with the PF-20T and PF-50T, a pair of all-tube bass amps they describe as “modern interpretations of Ampeg’s legendary low-wattage, all-tube designs.”

Rated at 20 and 50 watts respectively, the PF-20T and PF-50T both feature a pair of 12AX7 tubes in their preamp. The PF-20T has a pair of 6V6 power amp tubes, while the 50-watt version has a 12AU7 matched with a pair of 6L6 tubes. Ampeg fits each amp with a user-adjustable bias control for easy tube replacement. Each model can be toggled between 4 or 8 ohm operation and has a transformer balanced line out with a ground lift. Besides the increased power, the PF-50T adds a preamp output and EQ flexibility with a 5-position mid-tone control and Ultra Hi/Lo boosts.

Ampeg also announced the PF-112HLF bass cabinet to the series. The new cab follows the lineup’s aesthetic with black diamond tolex, a vintage B-15 grille cloth, and a 15mm poplar ply enclosure. It’s rated at 200W RMS at 8 ohms thanks to a 12-inch Eminence LF driver and 1-inch HF compression driver. The tweeter as a pad level control.

Ampeg’s new Portaflex models are available now. The PF-50T and PF-20T carry street prices of $899.99 and $599.99, while the PF-112HLF bass cabinet will go for $399.99.
