McIntosh MAC1500 Receiver - The Best Tube Receiver Ever? SkyFi Restored Arguably the best tubed receiver ever made (some will argue Fisher would take this honor) but definitely the best one McIntosh ever produced. The amplifier section is similar to the renowned McIntosh MC225 (what we vote the best amp from this brand) considered by many to be the best tube amplifier ever manufactured. The preamp section is another great McIntosh component. The tuner section is tube based and is similar to the McIntosh MR67, considered by many to be among the best tube tuners ever made. While the word best evokes strong emotions among audiophiles, knowledgeable audio experts and technicians agree that the quality of this handmade beauty is unparalleled. McIntosh tube gear from this era was handmade and is famous for being gentle on the tubes, leading to incredibly long tube life. Another interesting feature is the headphone section of this receiver which has a separate, specialized winding designed for using high end headphones. This feature exists in no other receiver I can find in the literature (borrowed from an Ebay listing).The McIntosh MAC 1500, introduced in 1965, is essentially a hybrid amplifier with a solid state preamp section, tube output section and FM tuner. It is a fairly rare piece of equipment as only around 2600 units were made for domestic U.S. use only.McIntosh later produced the 1700 which had solid state preamp and output sections and tube tuner. The later 1900 became a full solid state unit.The MAC 1500 puts out 30 watts per channel and is also know for having one of the better headphone sections of any receiver. It apparently has special secondary transformer windings specifically for the headphone output as opposed to the usual resistor placed in the speaker output circuit.It uses the following tubes: 4-7591 output, 2-6DS4, 3-6AU6, 6SC6, 6EA8, 3-12AU7, 12AX7.SkyFi Restoration Notes:Multi-section capacitors replace with custom reproduction parts9 ohm power supply resistor replaced with higher wattage partAll diodes replacedHeat stressed bias resistors replacedAll axial electrolytic capacitors replacedAll service manual audio adjustments completedTuner alignedDial lamps and stereo lamp filter replacedUnit has been retubed as needed.Output tube biased to .7V as outlined in the service manualBoth channels tested to 30W into 8 ohms before clippingTube Notes:Tuner tubes - Mix of original McIntosh labeled tubes and strong testing vintage and modern production tubes.Tube driver circuitry - Balanced Sovtek 12AX7 and (2) Philips JAN 6189WOutput tubes have been replaced with a modern production matched quad of Tung Sol 7591Cosmetic Notes:Minor blemishes in glass dial and front glassA few light marks are present in the top metal area and top of the faceplate frameRCA Jacks show wear. We find that these jacks have a smaller than usual diameter and a good quality tightly fitting interconnect should be used for best performanceSpeaker terminal blocks are fully intactWood cabinet has a couple of minor blemishes*Scroll down to view additional images for this listing and click to enlarge. **Please note we are not a repair shop and only restore what we own. ---------- SkyFi Audio - Curators of Vintage Audio Gear SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of high end audio equipment.
