Power Runs on Top of the Board

Post by kd »

All the photos I've seen show the power supply wires run under the board. I prefer to run them over the top, am I going to create a problem with this amp doing it this way?

Thanks,
Ken

Are you talking about the buss or jumper wires under the main board for plate voltage?

I don't think it matters that much, the Marshall guys run those wires on top all the time.

It just looks neater to have them out of sight.

Especially on a turret board since if they are on back and you heat up a turret too much the wires can fall out.

But it can be a problem when troubleshooting if you can't see them.
You can use a dental mirror to check them out without pulling the board.

PI, V1 and V2.

Building Marshall style amps is where I got in the habit of putting them on top of the board. Not pretty, but functional.

Since this amp has more gain than anything I've done in the past, I don't want to do anything to create any oscillation.

Well Ken,
All I can say is if you want the D tone, then you should follow HAD's layout as close as you can, these things can be tedious and the lead dress is a big part of the amp.

For example, the plate and cathode wires on V2 and V2 should be ran close together (touching) parallel to the board.

Have you seen the photos of ODS #124?

Here are a bunch of photos of D amps.

That's good advice that I'll follow.

Appreciate the tip and the link. I had seen the photos but forgot to keep a link to them. Thanks Tom.
