Now I want to do the similar component placement for 845 SE amp
I think of two component placement and want to have minimal interference

1st one is this photo

but question: The small Lundahl C Core is 300B to 845 ITC, Is the ITC too closed to 845 OPT which may cause interference, given I place the ITC vertical to minimize the interference but both ITC and OPT have no shield, do they still act like an antenna causing trouble?

The second placement configuration is this one

Question: Now the ITC is far from OPT but I place the input signal tube closed to 845 OPT, Does it also impact the interference

I am going to tailor make a 6mm Aluminum top plate with CNC machinery and electroplating. So I need to decide which placement is bug free

Thank for you knowledge input, please comment

Regards,
Eric

Don't know why you have the meter and the two knobs on the top. I would follow the Japanese example, find two covers for the small transformers and place them in a similar location as in the Japanese design.

I would have the meter on the front so you can see it from a distance or alatrnative move the two knobs to the front.

I would also get rid of the two chokes, they are unsightly. Just use a solid state capacitor multiplier, more effective too.
