Sound Pure's Take

Condition: Used, Very good

Original Transformer, footswitch and reverb pan, amp was recently serviced and all caps have been replaced. Original speaker replaced with Celestion A type.

This amp shows signs of age with various scuffs and some oxidation, considering its 55+ years of age, amp is in pretty great shape. 

 

 

From Other (Miscellanous Used/Vintage/Consign)

In 1960, a design engineer by the name of Jess Oliver created a combo amplifier with a chasis that could be inverted and tucked inside the speaker enclosure, protecting the inner workings and increasing the portability of the the amp. Nicknammed the "Portaflex," this amplifier became the standard in bass combos throughout the 60's and 70's.

Also in the early 60's, Ampeg was the first company to incorporate reverb in an amplifier. The Reverbrocket preceded Fender's Vibroverb (often thought of as the original) by nearly 2 years. In 1969, Ampeg set out to design the most powerful amplifier ever made. At that time, 50-watt amps were considered more than adequate. 100-watt amps were considered "plenty loud." Ampeg, however, not only harnessed 300 watts of pure tube power but actually created a new valve (tube) technology - Super Valve Technology, or the SVT. Now the most sought after stage amplifier, the SVT has proven its road worthiness on stages around the world.
