For sale is an excellent Conrad Johnson Premier Four power amplifier. 100 Watts per channel. This amp is massive and extremely well built. Giant filter and power capacitors. Weighs 80lbs on its own. I hate to part with this unit, but it needs to be played and not sit on a shelf. This unit has been well cared for and recently underwent pro servicing and tube upgrade including. Matched set of Mullard EL34 (x8). Here’s what is included. Tubes should be re-biased when you receive the unit. Very easy to do with instructions right on the chassis. Warm-up cycle is about 60 seconds from power on. Amp keeps sounding better the longer you play it. Additional description and specifications courtesy of Conrad Johnson. The Premiere Four vacuum-tube power amplifier used two pair of EL34 output tubes per channel to produce 100 watts per channel. It featured extensive use of conrad-johnsons proprietary CJD polystyrene capacitors throughout the audio circuit and in the regulated power supplies for the voltage amplification stages. The Premier Four achieved silky highs, and a remarkable three-dimensional soundstage. 4, 8, 16 ohm speaker taps (screw type). One pair of input. Built in bias indicators. Power Output: 100 watts per channel, minimum RMS, at 4, 8, or16 ohms both channels driven from 30Hz to 15kHz with no more than 1% THD or IM Distortion. Response: 20Hz to 20kHz, +0.5dB.

For your consideration is a used 1964 Fender Bandmaster all tube head. Overall in excellent condition, and perfect function.

All of the original parts: replaced capacitors, original power cable, Fender badge, feet, handle, metal corners, screws are included as pictured. This one has been modernized, but still has it’s 60′s soul! Sometimes these older amps need some TLC to get back to playing shape…. This one won’t need any work.
