Well, Mondial Mike;
I left the clip connected to grid of the first det., and with sig gen walked the IF peak down to 175 kc. with trimmer 1,2, and 3.
Then adjusted 1400 kc per instructions, then 600 kc, then 1400 kc.
Now getting stations in narrow bandwidths on 600 and 1400, but nothing in between!
Rechecked 175 IF it's ok. Swapped 27 osc tube with 27 1st AF, no difference
I see the article "unusual No Reception problem in model 90" in the Philco Library and will check out those items listed.
Regards,
Simon
