Is that a pair of those tubes that do not go in a socket but have solderable leads? I can't recall right now what they were called. If so, they are probably designed for battery use, thus low voltage/low current/low heat. That means that the tubes are probably mounted properly. It also means that the tubes are NOS, probably inexpensive, and there is probably a finite supply of them available, so if you've got one of these pedals you might want to stock up on replacements as they might become hard to find. They are also a bear to replace.

We could argue that tubes shouldn't be in a stompbox format anyway, since the stress from the box being constantly stepped on and kicked isn't good for any tube.

Those tubes were designed specifically for aerospace use. They were designed to resist vibration, shock, and rapid temperature changes. Im my humble opinion they are as resilient in a stompbox as a transistor, and probably less prone to problems than the pathetic sockets some builders use for passive components. I just wish I could buy some locally in the UK

Wow Thanks - ordering some (lots) now, I'm constantly amazed at the amount of websites I don't find

I have one that sounds farty and is somehow not working correctly.
I would happily donate it to whoever would be interested in reversing it.

Got a taker. The pedal will soon be flying its way across the ocean for a right proper demystification.
Thanks for all the PMs!

WTF is up with that! Aren't the people who design these things Engineers???Well, they certainly get the award for the most stupid way to mount a pair of tubes...

I stripped the schematic from the PDF for obvious reasons. If you compare with Indyguitarist Pics it looks to be correct.

Yes but I could not retrieve it. It is posted in the same area but it fails to download. It is the power supply section. Sorry man!
