Well, this is my first fm radio I have worked on, someone showed me the discriminator transformer. I was mistaking it for an IF transformer. More learning for me...... I guess its back to the calibration and see what I get. Learning as you go along can be a little interesting from time to time.....

Well, I went to check voltages to make sure there were no issues and I am having problems. Using a digital volt meter the circuits I have checked so far I am only reading 6.3 ac. the audio tube on the tuner calls for 340 dc on one pin. My meter does not read anything but an ac voltage. I tried it on my car when running it shows 13.87dc. in a wall outlet 122 ac. but every tube pin I have checked it reads 6.3 ac. Any ideas? the radio plays well but my fm is not calibrated correctly. I have fully recapped the set and played it for many hours. The voltages were checked from tube pins to ground like manual calls for. In the past I have used this voltmeter on tube tv's and never had this problem
