Here is your chance to own a piece of history. I just heard that Jim Marshall died in April of 2012.
It stands over 2 feet tall. I also have the amp schematics. Below is what they say about it.
MARSHALL 8015, 150W 1x15" keyboard/mixer combo, Made in England.
This keyboard/mixer combo amplifier was introduced in 1987 and was discontinued in 1992. It has 4 channels. I/Os include standard guitar plug inputs for each channel along with effects send and return, series loop in and out (for PA and external amp use), direct out and headphone out. Each channel has individual volume and effects sends with channel 4 also having additional bass and treble knobs. Other controls include a 4 band master EQ and a master volume.
It was fitted with a Celestion T4088 G15-150 8Ω 15" speaker and a Fostex FT300H 8&Omega horn driver fitted on a small plastic horn.
Although these amps do not contain any tubes, I feel that the Marshall amps story is incomplete without mentioning these amps. It isn't quite clear to me whether or not these amps were actually part of the JCM800 range, as these amps don't have the JCM800 logos, but they were included in the JCM800 catalog and they were manufactured in the same period and had the same looks and style.
It's a steal at $225 OBO.
