This is the venerable Marantz 8B, from the 1960's (about mid-60's), and a fierce competitor to the vintage McIntosh MC240 and Harman Kardon Citation amplifiers.

This Marantz 8B hailing from the late 1960's has received one of the most detailed and thorough restorations you'll ever find. No expense was spared in both time and materials, and is therefore priced accordingly. 

A quick look inside reveals German Mundorf and British Clarity Cap capacitors used throughout, along with metal film precision resistors. 

Besides the internals, cosmetically it doesn't get much better than this. The paintwork is near mint with only the slightest signs of use. Even the potentiometer covers are in place (!) which are almost always lost over the years. 

This amplifier originally retailed for about $275 back in the 1960's ($2,400 in today's dollars), and since their collectability is super high they're quite expensive nowadays and there are not many left. A lot of these suffered chassis rust, and because they are heavy and hard to handle many were also dropped, dented, and dinged.

Many of our clients end up purchasing two of these and running them as monoblocks. If you're looking to replicate this sweet setup, please just let us know and we'll convert two amplifiers for this use. We will install mono switches, plus matched tubes across both amps for perfect symmetry and gain.

It's very well built weighing in at about 56 pounds which is pretty amazing for a compact amplifier.

Output tubes are new Russian Electro Harmonix EL34's which we've found to sound warm and detailed. Driver tubes are mostly vintage.

All of this results in a wonderful sounding amplifier that's perfect for powering your vintage or modern efficient speakers.

Lastly, we found this fantastic website that has over a dozen documents available for download related to this tuner. Manuals, Service Manuals, Vintage Reviews, you name it and it's there. Click here to check it out.

Restoration Description:

This unit underwent an exclusive SkyFi Preservative Restoration. Involving a rebuild of the power supply which now features new silicon rectifiers and modern equivalent electrolytic capacitors. The original electrolytic multi-section cans were left in place to preserve the original look of the unit. Care was taken to relocate these capacitive elements within the chassis itself, utilizing a method that worked with existing hardware in the unit. A soft start thermistor was also added for additional safety margin at today's high AC Mains voltages. The original power cord was damaged and was replaced with an alternate 2 prong non polarized cord.

The Axial electrolytic capacitors in the tube circuity were replaced. All other signal path components were left in place to preserve the original sonic character of the amplifier. If you're interested in upgrading the signal path components with modern replacements, we can do this for an additional fee. Simply contact us for more information.

The EL-34 output tubes are modern production Electro Harmonix. The 6CG7 and 6BH6 tubes are vintage examples that were tested and selected specifically for use in this amplifier with our modern professional Amplitrex AT-1000 tube tester.
