Title: Need wiring for Stancor A-3823 Post by: AB3FL on August 05, 2010, 09:27:23 PM I am wokring on cleaning up my SX-25. Somewhere along the line the output transformer was replaced with a Stancor A-3823 universal. There are 6 pins on the secondary labeled 1-6. I know that the 2 P-P 6F6s like 10K on the primary. I have an 8 ohm speaker on the secondary. Currently it is connected to pins 1 and 5 but I don;t think that is correct for an 8 ohm speaker. I know this transformer is PW puny for the 6F6s so if anyone has a transformer with 10K on the primary for P-P and 8 on the secondary, I would be interested in buying/trading some stuff for it.

Pins 5-6 match 8.25 ohms to 10K p-p primary. The A-3823 is rated at 8 watts.

Lets try this again. To repeat, Looking at the chart for the Stancor A-3823, pins 1-5 match 6.95 ohms to 10K p-p primary. Pins 5-6 match 8.25 ohms to 10K p-p primary. The A-3823 is rated at 8 watts.
