I'm new to the forum and have been reading a lot of threads from Weber Tweed amp builders new and old.
Here's a question that maybe one of you builders out there can answer. Firstly, I just purchased a Weber Tweed 5E7M amp kit and am doing a dry run hardware assembly to check the fit of the parts. As you all know, Weber does not give explicit directions to anything on ther kits, but I don't necessarily need detailed instructions since I worked on tube type equipment in the military and have built a lot of power supplies and projects in my time.
Ok-- The issue is on Weber's chassis, they have pre-drilled holes for the Choke and the OT and the footprint fits both devices. Weber's layout drawing shows the OT between the PT and the Choke and as I stated above, the footprint on the chassis fits both.
Wiring the devices either way would work ... but I feel that placing the OT adjacent to the PT may induce 60 HZ hum into the output signal which is definitely not good. While placing the Choke adjacent to the PT will have not adverse affects since Choke is part of the power supply circuit.
Has anyone built this kit, and where did you place the Choke and OT. Or any comments on the attributes of placement of the Choke and OT.
On audio products that I have built in the past, I did not place the output devices anywhere near the power supply devices and had little or no 60 HZ hum issues.
