Internals are very dusty and they are all missing case screws. I did not try to repair or tinker with in any way. I am selling this as is for parts only. No returns for any reason. If you have any questions please contact me before purchasing. Again, assume these are only for parts, no returns. Ships to lower 48 only unless using eBay global shipping program.

Vintage ADCOM GFA-545IIStereo 100W /150W Stereo AmplifierFully FunctionalExcellent ConditionFully Functional Guaranteed About This ADCOM GFA-545II Amplifier:This ADCOM model GFA-545II is a tested fully functional Stereo 100W 8? Class A/B Amplifier that its cosmetic condition has some scratches and nicks to the painted metal top cabinet and on the edges of the faceplate. A printed copy of the ADCOM GFA-545II Owners Manual is included. This amplifiers outputs are strong and clean sounding.Features of the Amplifier are:The ADCOM GFA-545 II 2 Channel Amplifier is a powerful amp that gives you the strength and volume that your music needs. The audio inputs utilizes two high-quality, gold plated brass RCA jacks using Teflon insulation to minimize high-frequency losses, noise, etc. The speaker connections are of high-grade binding-post terminals that accommodates either bare speaker wire, terminal pins, or banana plugs, both single or dual.The ADCOM GFA-545II is polarity correct. It does not invert phase it outputs as compared to the input signals. The power cord of the ADCOM GFA-545II is a polarized AC plug.The AC On/Off switch is located to the front of the ADCAOM GFA-545II amplifier with a red LED indicating if the power is on or off to the amplifier.There are distortion alert LED indicator on the front panel to indicate forms of non-linear distortion such as THD, IM, slew-induced, clipping etc. There is also a thermal protection LED to indicate if the heatsinks for the output power transistors are overheating and that the amplifier has gone into protection. The protection circuit is automatically reset once the heatsink(s) drops to a safe operating level and the amplifier will resume normal operating performance.Triple-Darlington output stage reduces the effects of speaker impedance variations on the open-loop gain of the amplifier. Larger potted transformer provides better overall regulation for driving lower impedances at high power levels; also provides greater peak-current into loudspeaker loads.GFA-545II Specification:POWER AMPLIFIER SECTION Rated Power: 100 + 100 Watts - 8? 20Hz to 20kHz 0.02% THD / 150 + 150 Watts - 4? 20Hz to 20kHz 0.02% THDPower Bandwidth: 3dB down @ 1.7Hz to 100kHzDamping factor: >400 @ 20Hz - 20kHzTHD + Noise @ 100W 8?: 20Hz 0.008%, 1kHz 0.006%, 10kHz 0.008%, 20kHz 0.025%Intermodulation Dist.: <0.006% 4kHz to 20kHz @ 100W 8?,<0.009% 4kHz to 20kHz @ 150W 4?Frequency Response: 10Hz to 20kHz +0,-0.25dBInput Impedance: 100 k ?Input Sensitivity: 1.25V rms @ 100W 8?, 130mV rms @ 1W 8?Signal-to-Noise: >110dB IHF-A, 100 Watts w/ inputs shortedGain: 27dBRise Time: 2.3us @ 5kHZ, 70V peak-to-peak square wave, 20% to 80% Power Consumption (continuous, both channels driven): 50VA Quiescent, 720VA max., 325VA 100 Watts 8?, 550VA 150 Watts 4?BUILD Semiconductor Complement: 38 transistors, 2 zener diodes, 12 diodes, 2 ICs, 2 diode bridgesGENERAL Power Supplies: U.S.A. & Canada AC 120V 50Hz/60HzDimensions (W x H x D): 432 mm x 140 mm x 311 mm (17 x 5.5 x 12-1/4)Weight: 10.9kg (24.0lbs)Weight Packed: 10kg (22.3lbs.)

Very clean Adcom GFA 545ii power amp 100w/ch@8 ohms 150w/ch@4 ohms. Note that this is the upgraded, series ii with greater detail in low bass, flawless deep to mid-bass transition. Mids and highs only suffer a tiny bit in comparison to the best $2000 and up designs. Im selling it because I just got some new speakers for my home theater rig, and the 150 w/ch of the GFA 545ii isnt quite enough to wake up the bottom end. The quality is definitely there (in spades), I just need a little more quantity in watts, like at least 300w/ch.
