Vintage Conrad Johnson MV52 Vacuum Tube Power Amplifier - OB - EL34 -
Item History & Price
For sale is an excellent sounding Conrad Johnson MV52 tube amplifier.
Fully tested and operational. Excellent cosmetic condition. Beautiful liquid tube sound, but still holds together very nicely across the range. Wonderful soundstage, deep and rich.
Don't let the 45 watts fool you. This amp has plenty of power!
Includes:-two sets of tubes (installed pair have about 30 hours on them so they are nicely burned in. Other pair have unknown hours but still sound great)-Biasin...g tool (amp is already biased with installed tubes)-24k plated lugs to accept banana jack speaker cables (not shown)-Original Box, manual, inserts-Spare fuses
Notes: I don't use all of the screws to keep the cage on. There are a few "spare" screws in the bag that will be included as well.The tube boxes shown are the actual Tubes that are installed and show the arrangement as well. I put the spare / older tubes into these boxes.

MV52 Vacuum Tube Power AmplifierThe MV52 considerably refined the circuit design of the MV50 which it superseded. In the MV52 two sections of the input tube were connected in parallel to reduce the source impedance of the voltage amplifier, eliminating the cathode follower of the MV50. Probably the most significant change introduced in the MV52 was the use of polypropylene capacitors for the main power supply filter and reservoir eliminating electrolytic capacitors from the main power supplies. This was the first power amplifier to offer an all polypropylene main power supply. All other circuit capacitors in the MV52 were “cjd” polystyrene.Features:4, 8, 16 ohm speaker taps (screw type)one pair of inputstwo plate fusespower switchrack mount front panelSpecifications:45 watts per channel RMS, at 4, 8, or16 ohms both channels driven from 30Hz to 15kHz with no more than 1% THD or IMDInput Sensitivity: 0.80 Volts RMS to rated powerFrequency Response: 20Hz to more than 20kHz , +0, -.5dBHum & Noise: 92 dB below 45 wattsMechanical:Dimensions: 19W | 7H | 13 5/8D inchesWeight: 40 lbs.Amp will be securely packaged to ensure a safe arrival!
