Hi All, I am working on a Project with another Member, and we are looking to build this amplifier. We are using the Old Transformers from a Wards Console SE amplifier. The notation on the Schematic shows the output transformers at 2.5k ohms, But this was pasted from another website. Our output transformers are 500 ohms Primary, 1 ohm secondary resistance. Now, looking at the Power Supply, the choke I have no Idea how to size it according to what's there, much less if it's in the right place. I need some guidance in coming up with a value. If you know of a value you would use please let me know, that would be appreciated. The other point is where would I hook up the Bias pot and Meter for each channel, If I were to do TubeCad's Fixed Bias circuit, I would need a -36v power supply correct? I am not sure of the voltages if they are correct, I was going by the Wards Schematic for that! Any advice on this amplifier would be appreciated VERY much!!! Lydia
