2021年10月13日 · Bring on the latest affordable amp design from ARC!!! The VT100, a stereo amp rated at 100Wpc, uses four pairs of Svetlana 6550 output tubes and shares the more expensive VT130SE's ultralinear-configured output stage (see Wes Phillips's review), combined with partial cathode coupling designed for low output impedance and high current delivery.

The VT100 is a new all-tube, balanced stereo power amplifier that draws upon the advanced technology of the flagship Reference Series models. Rated at 100 watts continuous output per channel, the VT100 is a Class AB, differential circuit design using two matched pair of 6550 output tubes in each channel, along with four 6922 twin triodes per ...

2003年10月15日 · The ARC VT100 MKII can be improved markedly by using NOS 6H23 input tubes (try Upscale Audio, you need tubes matched to very close tolerances for the input). With these tubes the VT100 MKII becomes more dynamic, robust and full sounding with greater bass impact and punch while soumding more musical.

Changing the power supply energy storage from 270 joules to 540 joules, resulting in the highest energy-storage-to-wattage ratio in the ARC line. The VT100 could now boogie with the best of them. The change made the biggest difference in the amp's bass performance and in its ability to handle dynamic musical demands with ease.

2021年10月13日 · That final upgrade has resulted in the VT100 now having the highest power-supply energy storage per watt in ARC's product line. By comparison, the highly touted VT200 (see Wes Phillips' review in the October 1998 issue) has 674 joules of energy storage.

2021年10月13日 · Description: Two-channel, tube power amplifier. Tube complement: four matched pairs 6550C output; four 6922 drive; four 6922 input. Power output: 100Wpc continuous, 20Hz–20kHz, into 8 ohms (20dBW). Power bandwidth (–3dB): 15Hz–80kHz. Frequency response at 1W: 1Hz–100kHz, –3dB.

2024年10月3日 · Aside from a slight metallic coloration in the lower high frequencies, as well as a tendency to compress when presented with high-level orchestra at full throat (on my speakers, that is), the older ARC is a very detailed, neutral, and overall first-rate performer.

2009年12月29日 · I'm 99% sure that upgrades are no longer available. I called ARC and they said so. I've owned a VT100 for 10 years and it was 100% reliable, but now needs new tubes and maybe some board work. That is probably why so many are for sale used. When it comes tube-time, you may think about getting a new amp. But it was awesome for the time.
