Any help identifying the missing names or corrections would be greatly appreciated!
Ed, looks like we have a "Jesse" here?
If i read the name correctly, this might be one of the missing ones.
The sticker is different from the more common orange circles I see around here, being a white rectangle.
It's also placed on the lower main cap rather than on the chassis back.
No other stickers were inside this unit (I stripped out everything to bare chassis because total WOPL restomod ongoing).

My unit is a 400 Series 1, 220-40V, Serial No.1243-193A.
It's in Italy since the last 10 years for sure.
According to the Date Codes, my unit is the #193 built on December 1973.
Might fit as well with "Jesse" being on 1973 Christmas Card then...

Best,
Carl

Interesting serial number of your amplifier. What is the significance of the "A" at the end? Do the date codes on the power supply caps comport with a December 1973 build?

Sorry for the super late reply, hard months and now finally back at it!

On the letter "A", quoting Ed (oldphaser) from another thread: "The transformer (...) has a suffix letter “B” which means it is “B” stock". So MAYBE internal stock codes?

About caps yes, they include a 1973 date code and are by STM.
On top of that, all transistors feature the 7346 code (Year 1973 Week 46). Some photos below.
So yes, the thing have been untouched during the last 48 years; now up to another life with the full WOPL I've almost finished!
