Exposure Electronics 4 Dual

I`d like to keep this set  together if possible. From the photos you will see 3 pieces 2 makeup the Pre-Amp & Power Supply ( Exposure VII/VI ) and 1 Exposure IV Power Amplifier..   This pre amp has limited inputs but does feature an excellent phono section wonderfully labelled Gram for gramophone as well as a tape loop and a tuner input. All 3 pieces have had some update modification by a factory trained tech that include Tiffany Type RCA input jacks for all inputs and outputs.  The Pre-Amp has also seen a volume control update to an Alps potentiometer and the phono section has MC input loading of 470 ohms/6800pf the sensitivity is .60mV. The MM section has a loading of 47 k ohms /470pf/ and that output is 3 mV.   The amplifier has seen 5 way speaker terminals upgrades as well as a silver wire refit. Weighing in at 45 lbs per amp, on the bench each channel measures 90 watts at 1Hz into 8 ohm at .02% THD 20Hz to 20KHz and sounds fabulous .  You can see I've rated this setup as 7/10 because of the exterior condition which still good fits the condition criteria for this listing but really the shine is in the performance.     The posted images shows 2 of the model 4's however I've decided to keep one of these for myself.
