Item History & Price

Information:
Reference Number: Avaluer:7054436Brand: Magnavox
Original Description:
I have had these two Magnavox 138 mono-block amps for years.  The output of each amp is 10 watts and the output impedance is 4 ohms.  A few years ago, I refurbished the amps andpainted the chassis.  The amps are deadquiet and sound great.  A preamp ishighly recommended for volume and tone control. However, I did play the amps with just a phone and without a preamp andthe volume level was slightly lower. There are some scratches in the paint.Here’s w...hat I did when I refurbished the amp.  I replaced the coupling caps with Mallory andSprague capacitors.  I replaced out oftolerance resistors.  I added a groundedpower cord, a 2 amp slo blo fuse, an on/off switch, an on/off lamp, three-wayspeaker connections for either bare wire, spade ends or banana plugs and rubberfeet.  The filter can capacitor is stilloriginal to the amp and is still dead quiet as mentioned.The chassis are slightly different model 138 amps.  But both amps use the same tubeconfiguration, one 5Y3GT, two 6V6GT power tubes and a 12AX7 preamp tube.  One amp has a Hytron 5Y3GT, two RCA “smoked”black plate tubes and an Audio Research 12AX7. The other has a GE 5Y3GT, one RCA “smoked” black plate and one Sylvania “smoked”6V6GT power tubes and an RCA 12AX7.  Allfrom the golden age of tubes from the mid-century era.  All were made in the US except maybe theAudio Research 12AX7/ECC83.Free shipping in the lower 48 states.  More in other locations.For InternationalBuyers: This listing is in the eBay Global Shipping Program.  eBay handles and controls the invoicing andshipping if bought by an international buyer. I do not.  I ship to the eBayfacility in Erlanger, Kentucky, then eBay ships to the buyer.
