Guitar Amps

After the sweeping changes of 1976, very little changed in the guitar amplifier department in 1977. One model, the VT410 combo, was discontinued, and Carvin quit using Altec-Lansing speakers as optional upgrades, but for the most part, everything remained the same as the previous year.

1977 Carvin LM1200 Guitar Amplifier

The VT1500 series (right) tube amp and LM1200 series (left) solid-state amps were unchanged for 1977, however, the option for Altec-Lansing was discontinued in favor of JBL speakers.  The VT1500, comprised of the VTR2800 head and single SR690 cabinet, increased in price to $539.00, and the Super Concert STV1500-2, with two SR690 cabinets, increased in price to $779.00.  JBL K120 speakers could be added for $280.00 per cabinet.

The LM1200 amp, based on the ST2000 or ST4500 head and SR690 speaker cabinets, also increased slightly in price.  The LM1200, with ST2000 head and single SR690 speaker cabinet, was $519.00.  The SLM1200-1, with ST4500 head and single SR690 cabinet, sold for $589.00.  The SLM1200-2, with ST4500 head and two SR690 cabs, sold for $799.00.

1977 Carvin VTR2800 Tube Amp Head

The VTR2800 head (above) was the heart of the VT1500 series amps.  This all-tube 100W head had two channels (sustain [lead] and normal), with a 7 band graphic equalizer, master reverb, volume controls for each channel, and harmonic sustain control for channel 1.  It also had a selectable output wattage switch, and a B+ voltage control, which kept the tubes warm while the amp was not being used.  Two output jacks were wired in parallel, and a selectable impedance control was available, allowing 2, 4 and 8 ohm speakers to be used without impedance mis-matching.  The direct price on the VTR2800 increased slightly, to $319.00.

1977 Carvin ST2500 Amp Head

The ST2500 and ST4500 (above) solid-state heads delivered 125W and 250W respectively to power the LM series of amps.  These 2-channel heads had a 7-band EQ, master volume and sustain drive, as well as a 2-band parametric EQ on channel 2, and reverb and vibrato controls on channel 1.  Each channel also had a high and low input.  The ST2500 increased to $299.00, and the ST4500 increased to $369.00.

1977 Carvin SC2000 Power Amp

Carvin offered several other general purpose amp heads in 1977, including the single channel SC2000 & SC3000 (above) and the SV125 & SV250 (below).  These were 125W and 250W amps, and could be used for basic instrument amplification, as well as monitor and PA applications.  The SC2000 was priced at $249.00; the SC3000 was $319.00.  The AV125 was $209.00, and the SV250 was $279.00.

Although the VT410 had been discontinued, Carvin still offered a pair of combo amps. The VT312 (top right) was based on the VTR2800 tube head, and had a pair of MagnaLab 12" speakers.  It increased slightly in price from 1976, to $399.00.  It was also offered as the VT210, which was identical to the VT312, except it used 10" MagnaLab speakers.  The VT210 sold for $329.00.  JBL speakers could be added to the VT312 for an additional $140.00.

The ML300 (bottom right) was based on the ST2500 head, and also used a pair of MagnaLab speakers.  Like the VT312, it increased in price slightly, to $379.00.  It could also be upgraded with JBL speakers for $140.00.

As had been the case in 1976, Carvin's MagnaLab speakers were the standard in all Carvin guitar amps.  These would remain Carvin's speakers until 1985, and would lead to future Carvin speakers, such as the British Series BR12.

There were some minor changes in the various speaker cabinets Carvin offered in 1977, primarily due to the discontinuation of Altec-Lansing speakers in Carvin cabinets.  However, there was still a wide assortment to be had, using Carvin's MagnaLab speakers as well as JBL speakers.
