A * T AM' ' Amplifier is a Sound Investment
1000 uses — all seasons
Pam 16 or 17 uses a 227 tube in first stage and two 210 tubes in last or output stage. A UX28I half wave rectifier tube is also required. Price, without tubes. $125.00
Pam 19 or 20 has 227 tube in each of first two stages and two 250 tubes in last or output stage. Two UX281 tubes are also required. Price, without tubes, $175.00
PAC 2 requires one 227 for first stage, two 210 tubes for last stage, one UX281 and one UX 874 tube. Price, without tubes. $175.00
SAMSON Amplifiers are soundly designed to meet AIEE Standards and requirements of the National Board of Fire Underwriters; soundly built of best materials, soundly tested and have shown sound performance. Nothing has been left to chance — even the filter condensers are built to our rigid specifications to insure long life. Compensation is provided by our exclusive attachment plug for 105 to 120 volt 50-60 cycle line current and provision is made for UX 874 voltage regulator tubes where needed. Pam 16 for ordinary and Pam 1 7 for dynamic type speakers — for which the latter also supplies field current — deliver an approximate undistorted power output of 7 watts — usually ample for operating 12 to 16 loud speakers or 500 to 700 pairs of headsets.
Pam 1 9 for magnetic and Pam 20 for dynamic type speakers — for which it also supplies field current — deliver from 2^ to 3 times the undistorted power output of Pams 16 and 17.
Neither Pam nor PAC2 requires an output device between it and loud speakers due to the use of push pull output transformers. The PAC 2 is a combined power amplifier and A, B and C battery eliminator which supplies externally 45, 67 and 90 volts plate current, — 4§ volts C current, and raw AC for two 227 and five 226 tubes, The MIK 1 is the only completely AC operated amplifier of its kind. It is designed for use with a standard two button carbon microphone and supplies current for it. The output terminals connect directly to the input terminals of any PAM amplifier. It has volume control and microphone rheostat — which with switch and miiliameter permits quick balancing of button currents. The MIK 1 uses the same high quality microphone input transformer that we supply to many of this country's better class broadcast stations. Like all the foregoing units it has a combination of famous Samson Symphonic and Samson Symphonic Push Pul! Transformers in its amplifier.
