I made a quick layout of my filter cap board, this should work.

Completed another round of checking my layout against the schematic, found and fixed 2 more errors. I think I am ready to start ordering parts.

This has been fun journey and I learned a lot, and I can finally see the light at the end of the tunnel.

If anyone spots any errors or anything that could be better please let me know.

Thanks for all the help!!

That looks good!  Congrats!   


Did you mean to put the mid-boost on a relay?  That's fine to do so but there is no advantage of using a relay to switch the midboost unless you're using a footswitch.  A manual spdt toggle will accomplish the same purpose.  The relay is only for a footswitch hands free approach.


You would use a stereo jack if you want foot switching both the clean/OD and the mid-boost. 


With respect, Tubenit

Yes, I figured if I wanted to add mid boost to a footswitch later all I need is a stereo jack and a three button foot switch for clean/OD, midboost and reverb.

I have a feeling I will be adding mods after I get a feel for the amp.

Thanks again for all your help!!

Well, there's no turning back now!!  I have ordered my custom board and every part that Doug stocks. Need to source the rest of my parts. The board ordering process was very easy, this was my first time ordering a custom board. I may have to do this again!!

Time to get this party started!!!

Starting my build, have the filter cap board, relay power supply and relay boards built. Still waiting on some odd resistors, need to punch a hole in the chassis for my rectifier tube.

Making progress.
