Jolida vacuum tube amplifiers
amplifiers now have a nice transformer cover and are
silver and black rather than the old gold tone finish.
They have also added a new 12AX7A preamp tube and use
separate 12AT7 tubes as drivers for the power section. A
nice, compact design that offers clean sound and a cool,
retro look for surprisingly not much money!
