De vanzare un super-rar McIntosh MC240, made in USA, amplificator de putere, este model final al seriei (1969), in stare excelenta de functionare.

Adevaratul sound McIntosh pe lampi! Va astept la o auditie!

Vine echipat cu:
4 lampi 6L6GC de la General Electric in stare excelenta
3 lampi 12AX7 / ECC83 Telefunken NOS (1 x voltage amplifier, 2x cathode follower drive)
2 lampi phase inverter 12AU7 / ECC82 de la NEC Japan
2 lampi drive amplifier 12BH7 General Electric

plus transformator extern multi voltage IN, multi voltage OUT, 230V - 120V de 1kWh putere.
Amplificatorul poate fi selectat cu 2 intrari de tensiune 117V/125V.
Transformatorul oferit de mine (Misumi Swallow Electric Japan) are intrari si de 220V si de 240V plus iesiri separate si de 100 si 120V, in fct de tensiunea din zona dvs va puteti parametriza o tensiune foarte apropiata de specificatii,

Harmonic Distortion: Less than 0.5% at rated output or less, 20 cycles through 20,000 cycles. Typical performance is 0.3% or less at 20 cycles and 20,000 cycles at full power. Typical performance in the mid frequencies is 0.1% or less at full power.

Intermodulation Distortion: Less than 0.5% for any combination of frequencies from 20 cycles through 20,000 cycles if instantaneous peak power is below twice the rated power.

Phase Shift: Less than +6° 20 cycles through 20,000 cycles

Frequency Range:
At rated output:
+0, -0.1 db 16 cycles through 40,000 cycles
+0, -0.5 db 16 cycles through 60,000 cycles
At one-half rated output:
+0, -1 db 10 cycles through 100,000 cycles

Noise and Hum: 90 db or more below rated output
