Point to point wiring

This is my crows' nest style of point to point wiring of a guitar amplifier built into a Hammond AO-64/68 chassis, using the iron of the same K-100 organ:

Admittedly, there are two perfboards, too: One holding a relay for treble boost, the other one populated with a voltage tripler, the LTP phase inverter cascode CCS and the output tubes' bias adjustment trimpots.

Best regards!
 
I have built 2 point to point amps so far. Both times I created them first using the physical layout drawing in DIY Layout Creator. This helps with locating bulky items and checking how many tags per tag strip. In the real world there is a 3D element, but access to components and pins is important, i think.

DIYLC is a bit fernickety with bending leads on components, but is free and support my wishes.

Any other approaches or tools?

Wow, some really beautiful point-to-point builds here. Some are even deadbug style, which fascinated me when I first saw some CMOY headamps done this way years ago.
I think kodabmx takes the cake so far.
Any recommendations for a simple (but good sounding, of course) point-to-point tube pre or buffer for 2023 to keep the spirit of diy hobby active? I want to explore tube builds.

Using a tool like DIYLC you can build a circuit you like on your pc, looking up component sizes and pin layouts to help. Then run it up the flagpole hete and you will get some helpful feedback.

Preamplifiers are particularly fussy wrt layout and lead lengths. I am building up to that after a couple of push-pull amp projects.
