Efsane Lambalı çok temiz ve ilk günki kondisyonunda

VT200 power amplifier: dual-mono tubed power amplifier with ultralinear output stage. 

Tube complement: eight 6550C in matched pairs, ten 6922 (six driver, four input). 

Output power: 200Wpc continuous into 8 ohms (23dBW), 20Hz-20kHz. THD @ 1kHz: typically 1% @ 200W, <0.01% @ 1W.

Power bandwidth: 12Hz–120kHz, -3dB. Frequency response: 0.5Hz–200kHz, -3dB @ 1W.

Input sensitivity: 2.5V RMS, balanced or single-ended (27dB gain into 16 ohms). 

Input impedance: 200k ohms balanced, 100k ohms single-ended. 

Output taps: 1, 2, 4, 8, 16 ohms. Output regulation: approximately 0.8dB with 16 ohm load to open circuit (damping factor approximately 11). 

Overall negative feedback: 10dB. 

Slew rate: 25V/µs. 

Rise time: 1.5µs. 

Hum & noise: <0.2mV RMS, 109dB below rated output (IHF weighted, input shorted, 16 ohm output). 

Power-supply energy storage: approximately 674 joules. 

Power requirements: 105–125VAC, 60Hz (210–250VAC, 50Hz); 990W at rated output; 1200W maximum; 680W at idle.

Dimensions: 19" (483mm) W by 10.5" (267mm) H by 23.6" (600mm) D. Handles extend 1.5" (38mm) forward of front panel. Weight: 118 lbs (46.5kg).
