DC-34 Holders 1690 KC to 4400 KC steps of 10 KC ea. . 1.19 Some of these earlier sets used a constant* voltage transformer to offset the degradation in performance at reduced input voltage. These transformers were manufactured by Sola and were of the saturable reactor type, While they were used primarily to compensate for primary voltage variations, they also provide good regulation with changing load. The RA-109 chassis, used in many sets marketed in 1951, is typical of those using the...

Step 9 Connect 0.1 ceramic capacitor T to terminal 2 of terminal strip TA. Step 10 Cut wire 3 inches long and put spade lugs on each end. To be used to short terminals 1 and 2 of terminal strip T when amplifier is tu l> e used with no standb cutoff bias and with high operating bias for class C CW* This completes the modification. Now of course this small unit can be mounted on a separate chassis and wired to the outside of terminal board T but it makes a cleaner job to do it on the inside....

6u8 - Superhet Modern

Ceiver uses a series-parallel heater string, it was necessary to change the 6U8 to a 12AX7 and connect the nuvistur in parallel with the 12AX7. Another solution would be to add a second nuvistor as an rf amplifier. The results are amazing, as the limiter completely eliminated all ignition noise from my XK-140, which was so noisy that I gave up trying to operate 2 meter mobile from it, Willi very little effort, it should be possible to add this limiter to any receiver, and eliminate almost all...
