The JOYO JTA-05 Sweet Baby 5 Watt Tube Amplifier utilizes a 12AX7 as the preamp tube, a 6V6GT as the power tube and unlike almost all other amps in its price range it has tube rectification via a 5AR4 tube. Giving a truly vintage tone thanks to the all valve, all hand-wired, class A circuitry, with the valve rectifier giving you the vintage 'sag' tone as heard on countless records.
A 5W low-output class A guitar amplifier with a sweet warm sound you can get in your room!
Vintage circuit design. This amp uses Ruby tubes.
One 12AX7 at the preamp stage and one 6V6GT in the power section to drive a Celestion Super 8 speaker.
There is a 5Y3GT at the power supply stage, but it can be changed to a 5AR4 if you want more output power.
