Is it possible to flip the 5F6A layout in Visio? Reason I am asking is I am planning on gutting the organ amp I made and remake it into a 5F6A. But my problem is the location of the PT and OT is already established. So in order to make it work I need the controls and the tubes flipped on the layout. Could any of you guys using Visio do that?
-
Yes. Just select everything on the page and group together. Then flip horizontally. You can probably get the vsd file from Doug.
-
There's another way to do this without using Visio. Just download Hoffman's pdf. Open it up and save the layout as a png image file. Now open the png file in your favorite image editor and flip horizontal or mirror horizontal. The downside is that all the text will also appear backwards. Might be a big deal for some people.
Text is not flipped in Visio if that's important to you.

... You can probably get the vsd file from Doug.
I think he was hoping you could flip the layout for him & provide...
-
Maybe he could ask Doug to do this. Without the vsd file this is the best I can do...

Cool! Dimm, ssab, and of course elbert.

11teen, What does that mean?
Thanks Steve, I was just wondering if it was do-able, not particularly asking anyone to do it. I figured also that I could print out the layout and then flip it and trace it on another sheet.
Steve, what I am striving for is flipped top to bottom, not also left to right. So the one you did is backwards in the order of the tubes and inputs/pots. I think I'll just flip it myself and locate the
turrets and such.
-
But on second analysis Steves flipped version might just work. I'll give it a go. Thanks again ..
-
That's a lot of work! Do you have Visio? If so, it only takes about 15 seconds to totally flip it. Only takes a couple minutes to produce the image I posted above using Acrobat and a graphics editor.
If the main thing you need is a flipped board, you could just have Doug make the board for you but install the turrets on the bottom side. Or if you make your own boards, you could do the same.
But if you have Visio, just quietly ask Doug for the vsd file.

The white knight is talking backwards. :icon_biggrin:
Look at my flipped pic and try reading some stuff.

...what I am striving for is flipped top to bottom
Ah, I did the wrong flip. Here's a vertical flip and also a vertical/horizontal flip. These images show a view from the bottom of the chassis.
-
Ah so I get it now,, hahaha thanks Steve I think I can progress with what you have done. I don't have Visio, but would like to have it. ;-)
-
... I don't have Visio ...
None of what Sluckey did requires Visio. Guaranteed there is a free photo program on your machine which would do the same.
-
OK second question. How can I get the board drill template separated from the rest of the diagrams ? Possibly use Photoshop?
-
It's already separated. Look at page 4 of Doug's pdf.
-
Thanks Steve - I opened it in Photoshop and was able to select page then rotate and flip it. Could also size it to any spec. I don't need the 4 turrets on the bias end for the filaments. It looks like I could save 5 turrets on that end. My PT does not have a bias tap, but I noticed the Doug's Plexi 6V6 uses a bias tap off one leg of the PT primary and all that is different in the two bias circuits is the bias range resistor and where they tap in. So I think I am good to go to make this board, if I have enough turrets. (fingers crossed) The Baldwin #40 was cathode biased.
HPB you were right sir, and thanks for the info about flipping images, I forgot that Photoshop could do practically anything, also I saw one could do it in Paint.
-
Just a thought... Since you will be making your own board, you really don't have to flip the drill guide. Just print it full size from Doug's pdf, tape it to your board and drill. Now just flip the board over and install the turrets on the back side.
-
Right on thank you. Now I'm debating on keeping this huge monstrosity of a choke or getting a new one that has a smaller footprint and less weight. Not really sure that size matters after a certain point.
I also noticed Dougs 5F6A has pins 1 and 8 jumpered on the 6L6 sockets. Was that a plan to use EL34's? Because I am planning on using EL34's in mine. :-)
