This is a World Wide Electronics tube combo amplifier with a 4 speaker. These amplifiers were made in the 60′s and there were no power transformers included, they ran 120V AC direct to the amplifier circuit. This was unsafe as it could lead to high voltage shocks. I It was modified by adding a 120V to 120V Isolation transformer between the power plug and the circuit which isolates the user and eliminates the danger of shock. To ensure that it stayed cool it also has a fan added on the back. It also has a modification that adds a 1/4 jack to the back where you can plug in an extension cabinet using a speaker cable if you want to hear it with a bigger speaker. This amplifier sounds amazing with an electric guitar plugged in and it gets fairly loud. It also handles pedals well. The condition is extremely clean. The Tolex looks really clean and the weaved material on the front looks perfect. The tubes are 35W4, 12AU6 & 50C5.
