Jennings Electronic Industries J100 combo
Sounds Incorporated, early or mid 1969, with a good line-up of Jennings solid state equipment: two J100 combos, a B100 bass amp and 2x15" speaker cabinet; an electric bongo drum; a 100W PA amp and two column speakers; and a Gyrotone.
J100 combos were elegantly slim, their depth being little more than the depth of the Celestion drivers. At back, the cabinets were open, the two panels blanking off around two thirds of the speaker compartment.
Along with the J40, the J100 was one of the first guitar amps marketed by Tom Jennings's new company, initially "Jennings Electronic Developments" (in mid 1968), then "Jennings Electronic Industries" by 1969.

Behind him, two J100s, one stacked on top of the other, and among other things a pair of "Jennings Sound" standees - the one on the left naming Dave Clark, and Brian Bennett of the Shadows, the one on the right Hank Marvin.

The J!00 remained in the Jennings catalogue through to mid 1973, when the range as a whole was revamped.

A striking advert published in February 1970 to coincide with the Frankfurt Fair.
"Beat Instrumental" magazine, also February 1970. Note that the J100 was available in three formats - the amplifier as a separate, a combo, and with a D4 (4x12") speaker cabinet.
The price of a combo was £215.00 against £225.00 for the amplifier and separate D4 speaker cabinet. The Shadows are recorded users of the latter set up. Through to late 1972 prices remained relatively stable. In mid 1973, they were reduced substantially. A few months later the J100 and J100D were deleted from the Jennings catalogue.
