These are probably already familar to a lot of you here but I thought I would post about it for the new members . The concert Grand was made
1958-1961 it had 40 tubes in it! It had two separate 2 channel amplifiers for bi amping the two 15" woofers and two 1,000 cycle exponental horns
Each amplifier chassis had 2 5U4 rectifier tubes. The separate tuner chassis had one 5U4 of it's own as well. The amplifiers in total had Sixteen 6V6 output tubes eight per chassis .6 driving each woofer in parallel push pull and 2 in push pull for each horn
The concert grand had an English made Collaro record changer as did many other Magnavox products through the years
This was TOTL then It took about 16 months to get one.Most were special ordered . Quite a statement piece for them and priced accordingly .
Antique Radio and Audio kharma forums have a lot of info about these.

Magnavox Debs Concert Grand Stereo Console

Fort Wayne, Ind. -- Magnavox joins the limited edition class of the console phonograph field next week, with first delivery of its Concert Grand stereo instruments. The Concert Grand, listing at a price ranging from $1,000 to $1,100, depending upon what selection is made of six different wood finishes in three models, traditional, provincial and Danish modern, offers a new peak, too, in Magnavox electronic instrument price and also offers an industry high of 200 watts peak power in a packaged stereo unit.

Two firsts in the Magnavox Concert Grand are an automatic signal-seeking FM-AM radio, such as was introduced initially in the Cadillac car radios and a remote wireless control of the four-speed phonograph that enables the listener to turn the record player on or off, raise or lower the volume, reject or change records, from anywhere in the room with a finger-tip control instrument very similar in appearance to those utilized in some TV sets. The remote control also changes AM-FM stations, automatically selecting every usable station.

All three different styles of cabinetry offer heavy glass panels on top of the console to protect the natural grain wood finishes from stain or burn. The record changer is reached thru a center gliding panel, while Magnavox sound equalizer controls are hidden behind a center gliding panel in the front of the instrument.

The Concert Grand's sound system is powered by a separate 10-watt treble amp and a 40-watt bass amp in each stereo channel, while each channel has its own 15-inch bass speaker, each having 42-ounce magnets, and its own 1,000 cycle exp
