1949 Fender Deluxe Amplifier. Serial number 1771. Tubes are Zenith 5Y3 rectifier, 6V6 power tubes and two zenith metal 6SC7. Original grille cloth. Original laquered  tweed cloth. The small transformer is a Trico 1839. The large transformer is a Trico 6452. The 1 meg pots are coded 304 9 48 and 304 9 49. Meaning CTS pots made the  48th and the 49th week of 1949. Both back panels are the original tweed panels with the proper slot head screws. Mr Phillips had not invented his cross top screws yet.  I have owned this amp about twenty years. Now it is a great sounding amp. The amp had lost  its sparkle. There was no life to it. I took it to the Amp Shop here in the Reseda area right next to the Old Norms Rare Guitar shop on Tampa. The tech said that the capacitors were dried out and the caps were replaced. I took it home and tried it out. The original 1949 Jensen speaker could not handle the power with the new caps and it started to smoke.  I played the amp through a 2 x 12 cab and it sounded great. I finally got the speaker reconed by Orange County speakers who specialize in old Jensen speakers. Now the amp sounds great. There is a secret to these old Deluxe amp. The two channel volume controls are interactive. To really get the sound we all love out of these amps you have to put the channel that you are using at 10. The second channel should be on 7 maximum. If you go past 7 on the second channel, you will lose all the highs and tone and the tone flattens out. Try it. Play it on seven on the second channel  and it sounds great. Go past seven and it loses all its sound. A very cool amp.
