Or I can bend the PCB mounting pins on the pot by 90 degrees and it just fits. Once I get the SPST switches I think it will work out. Hooray!

But I will definitely adjust the GGG template for next time.

Yeah, a bit too snug in there, fraught with problems. I usually build first then box after, just my preferred method, very rarely have I got everything to fit the other way around, I really need to see everything first.:)
I thought that by using the GGG template that they would have sensible spacing. Once I get the smaller SPDT switches I think I can make it work. If not, then 9mm pots might be required.
We have slightly different build preferences then. I like to drill the enclosure and mostly do the off-board wiring in place so I can get the wire lengths just right.
Fair enough. I did think of the 9mm pots when i saw those 16 mm ones but I still wasn't sure of the clearance with the jacks positioned there when the jack is in place.
The photos don't really show, but there is plenty of clearance vertically between the 6.5mm jacks and the pots. 125B enclosures have a lot of height. The only clearance issue is between the pots and the switches. My SPST switches arrived today so I will test this evening. Hopefully I will have enough space that I don't have to junk the enclosure.
And I will make an updated copy of the template for next time.
SPST switches did help, as did a bit of pot leg bending to get another mm or 2. It's still a tighter fit at the top of the enclosure than I would like, but should be workable so long as I insulate with electrical tape to prevent accidental shorts.

Also got the primer on the enclosure today. Going with a British racing green in keeping with the original.
Tidy as!

Finished the off-board wiring tonight, but still haven't boxed since enclosure isn't ready. Hooked up to the amp and spent 5 minutes wondering why there was no sound at all.
Debugging was easy. I hadn't fitted the op amp into the socket 😊
After that, it works nicely. Didn't spend any time dialing it in, but all controls work as they should
the first test:

I haven't soldered the power jack, LED (and current limiting resistor) yet since the jack needs to be wired into the enclosure, so I used alligator clips to a 9v battery.
