Well I went and followed the directions and aligned the 71. But now the sensitivity is gone only pulls in a couple stations. My sig gen is pretty accurate and everything worked out but now its all messed up.
It said to put an output meter on the cathode and plate of the 42 output tube. I used a VTVM on the 42 but there wasnt much deflection on the needle I ended up just doing it by ear.
I set the Sig Gen to 260kc and injected the signal into the grid of the 36 Osc tube. I peaked the IF's then moved on to HF tweaking. I set the dial to 1400, and the Sig gen to 1400 and injected the signal into antenna connector on the radio then peaked the HF lug on the tuning cap (rear lug). Did the same for the Low Freq. at 600. I didnt understand what I was supposed to do witht the Antenna and OCS lugs on the tuning cap (front and middle lugs).
Anyone wanna try to help me out. Ill tinker with it tomorrow.
FYI I did have it playing well before I tore it apart to clean the chassis so I know it will work.
