Description

Version differences

The design of the DS-1 has changed little throughout its lifetime, but the opamp this pedal is based around has changed several times. From 1978, the DS-1 was using the Toshiba TA7136AP opamp. In 1994 the Toshiba opamp was replaced by Rohm BA728N. In 2000 the opamp was changed again. The Mitsubishi M5223AL was now used. The last change was 2006 when Boss introduced the New Japan Radio NJM2904L opamp in the DS-1.

The DS-1 went through a few cosmetic changes in the early years of production. The first version had a clear switch, silver thumb screw and the D in DS-1 placed directly underneath the t in Distortion. This is usually referred to as the long dash version. The clear switch disappeared around serial number 8700, the silver thumb screw at serial number 0500 while the D in DS-1 ended up under the i in Distortion around serial number 14xx00 (short dash version). Since early 1982 the only changes has been to the bottom label. It changed when the production moved from Japan to Taiwan i 1988 and a silver label was introduced when the circuit was modified to accept the PSA adapter 1994.

The CE-5 is the 4th pedal in Boss Chorus Ensemble line. The major difference between the CE-5 and its predecessors is the additon of a level control and a high and low filter control. It has been in production for longer than any other chorus in the CE series but remained virtually unchanged until it received a major overhaul October 2001.

Version differences

There are 2 versions of the CE-5 where the second version is denoted CE-5A. This is printed on the PCB so it is easy to figure out which version you have. The first version is closely related to the CE-2 and CE-3. It uses the 1024 stage Panasonic BBD MN3007 and its associated clock driver 3101. The CE-5A is completely restructured. It uses surface mounted components and the BBD has been replaced with a digital design. All CE-5s made before October 2001 will have the old analog BBD circuit. The easiest way to determine which version you have is to use the serial number. If the second letter/first number combination is earlier than P1, you have the analog type. This also mean that all digital CE-5s will have a dark gray label.

As such, the payments are influenced by pre-established performance indicators agreed upon with the EaaS provider. As frustrating as viruses and worms are, perhaps more time and money is spent on resolving virus. Or it may rely on microgrid output if the grid is under strain, such as during summer afternoons when power prices rise. At other times, if allowed, the microgrid owner sells the microgrid’s idle capacity to the local utility or wholesale market.
