Default GS-31B LINEAR Base Amplifier





WIZARD BASE AMPLIFIER, WITH A GS-31B TUBE . ALSO HAS A HEAVY DUTY 1/2 AMP POWER TRANSFORMER SURGE TO 1 AMP. COMES WITH INPUT AND OUTPUT TUNING. IT ALSO HAS bias diode voltage dropping assembly, The assembly is used in For CT circuit of the RF chassis to set bias to the tubes. This adjusts the resting current of the amplifier and sets the class of operation. This amp is ran on 120 volts AC with a 15 amp of draw.
50 watts key and 210 watts peak input drive gave me 650+ watts RMS and 1800+ peak....

a wizard built on 15 meters. I could imagine that QSO.

what kind of amplifier are you using?

A Wizard Built.

(hammy being confused that he didnt say ameritron,icom,kenwood) A Wizah what?

You can get a diagram of that amp here>>Palomar Electronics Corp. Skipper 300
I have a 310m (mobile version of the Skipper 300 8950 tube box.
It has a terminal strip that the appears to hold the trans-stage tuning inductor coil. On the oposite side of the strip there is a wire wound 20ohm cap,,,,do not want to guess the wattage. Thing is about 1.5" long though. One leg is on terminal 2 of the strip (top to bottom) and shares that terminal with a ceramic disc cap, the other leg is soldered to the bottom most terminal and again shares it with a leg of another ceramic disc cap.
It appears to bridge the 2 caps across the legs of the caps that are closest to each other. The other leg of the upper cap is tied to the inductor coil, the other leg of the lower cap appears to be tied soldered to a ground point below the last full terminal.
Hope this helps.
I can't get any pics from flickr to load.

I had one and I liked it, you could key it for a long time and not worry about it, no tvi problems, built well, built like a tank, got 1000w pep with only 110w of drive. felt like it had more in it. pain to use since you either needed a relay or a footswitch.... too goddamn heavy
