ESS 400AMP & PREAMP Vintage ESS Audio Components

Very well preserved ESS components. I haven't been able to find much info. on these so I'm hoping another audiophile will recognize them for what they are. When I picked them up I had a local tech replace a cap in the preamp allowing enough voltage to switch the protection relay. Preamp takes about 7 seconds to fire. Both pieces could use a good cleaning. Some very minor static through volume control, but nothing that would damage a speaker. Wood cabinets are very nice. I haven't played them much, but I did notice that the volume would decrease slightly in the left channel and then come back, very rare....has only happened twice in the last hour of listening. These have been sitting for years. Other than that, these components sound great. Selling as is. Shipping will be pricey on the amp....I'm estimating shipping on both pieces around $75. Email with any questions.

Here is a youtube clip of them playing:
