Paragon Low Power Mod

From the Ten-Tec Reflector October 28, 1996

Instructions for modifiying the 585 Paragon I for low power operation:

Replace R44 with 10K ohms on 2nd mixer board. Reset ALC for 100 watts. This mod gives a range of 100 watts down to approx. 2 watts.

Went looking for R-44 as mentioned by Scott Robbins on the 2nd mixer board. My board is NOT like the one in the manual so this fix may work only on early Paragon 1's.

I found U-1 P-6 and traced it to a resistor that was already 10K but it is in the position on the board that calls out R-39 and the other side of this R-39 goes to the emitter of a transistor that is not even on the schematic! I paralleled the 10K (R-39) resistor with another 10K resistor by tacking it on top of the original. Now my power will go down to 5 watts. I did not have to re set the high limit as it did not seem to change. I still get 90 watts full power out, so I'm happy with this mod .

Your milage may differ………be careful out there, as things are not always as the manual / schematic says! ……… :-)
