Vintage Conrad Johnson Premier 10 Tube Pre-Amp
UP FOR SALE.
Is a vintage Conrad Johnson Premier 10 Tube Pre-Amp.
See Description Below.
I am selling a Conrad Johnson Premier Ten Amp vacum tube Pre-Amp. It is in excellent cosmetic condition. Component powers on and all tubes appear to work but I am not sure of their age. It is being sold as is so please ask any questions you may have up front. I inherited them from a long term friend who used them almost daily, but I have not used them at all so do not know there condition other then power on, which is the main thing.
Premier Ten Line-Stage Vacuum Tube Pre-Amplifier
The Premier Ten was essentially two mono preamplifiers sharing a line cord and power transformer.
Specially constructed controls maintain a physical separation between channels to reduce capacitive-coupling and minimize crosstalk between channels. Individually regulated power supplies electrically isolate the two separate channels.
Derived directly from the Premier Seven, the audio circuit of the Premier Ten consists of a single triode amplifier direct coupled to a triode cathode follower. The low output impedance of the cathode follower permits the use of the Premier Ten with highly capacitive amplifier interconnect cables without attenuation of the high frequency information. The zero feedback circuit insures temporal accuracy and spatial detail.
The volume control is a 23 position switch selecting among 23 pairs of resistors never more than a single-pair of resistors are inserted in the signal path by this control. The balance control is an 11 position switch that is electrically out of the circuit in the centered position. There are no carbon-track or conductive plastic resistive elements to degrade the audio signal in the Premier Ten.
