The Caliber series was launched in November 1985, the first model was the Studio caliber.22. These were the first inexpensive low-wattage amps. .38 Special (with four EL84 tubes, 38 watts) and .50 caliber (two 6L6 tubes, 50 watts) were listed in the 1986 Product Guide. The 4x EL84 model was released in January 1987 and was produced until the end of 1988. As a result, these were replaced by .50 caliber with 6L6 tubes with pull-channel switch from min. 1990 to 1993 under the name .50+ cal. In 1993, these were replaced by dual-caliber amps, making this one of the last.<\/p>\n
