I have a 1967 Sunn amp brochure and I just wanted to add some information regarding the Sunn Sonic I amp. The 1960's Sunn amp chassis came in two power versions; 40 W and 60 W into 8 ohms. The Sonic I was a 40 watt amp, and it came with a single JBL D130F in a 24H x 24W x 15D speaker cab. It also came in a bass version, called the Sonic I-40 that came with a single JBL D140F speaker. The Sonic II was the 60 watt version that used the same chassis as the 200S. The only difference between the Sonic II and the 200S - other than the name on the faceplate - was the Sonic II came with 2 JBL D130F speakers in a 42H x 24W x15D ported cab, while the 200S came with 2 JBL D140F bass speakers. The 200S speaker cab was the same size as the Sonic II, but it was of a bass reflex design.
Sunn made amps that had the same name but were designated either I or II. Ex: Sentura I and Sentura II, Sonic I and Sonic II, Spectrum I and Spectrum II. The amps with the designation of "I" were the 40 watt version that came with one speaker in a cabinet, and the amps with the designation of "II" were the 60 watt version with 2 speakers per cabinet. The Sunn 100S was a little different as it had the same amp head as the Spectrum II, but the cabinet had 1 JBL D130F speaker and a LE100S horn with a crossover.
In 1967 Sunn also had 2 PA systems - the Coliseum Sound System, and the Studio Sound System. Both used the same PA head, which was 120 watts and had 4 KT88 power tubes. The PA head had 4 inputs, 4 volume controls - one for each input, one treble and one bass control for the whole system - no separate EQ for each channel in those days-, and a reverb control. The Coliseum was a three-way speaker system. Each of the two main cabs ( 42' x 24" x 15") had two 15" JBL 130AS speakers and a JBL 2402 bullet tweeter. On top of that was a box with a JBL mid-range horn driver combo with diffuser lenses on the horns. The cost for this system listed in the 1967 price list was $3595.00, a lot of money in 1967.
The Studio Sound System speakers had the same basis components as the Sunn 100S guitar amp, except the speaker was a JBL 130AS and not a D130F, and it had the same LE100S horn and crossover. The price for his system was $1395.00.
FYI, The list price for a Sonic I amp in 1967 was $665.00.
