The black power transformer would definitely not have been present in a '61 instrument.

If the speakers are dated late '62 then the bench is either not original or the owner got the year wrong by accident while scribbling on the card.

When you hit the "Submit" button you will see a message advising "Update Successful".

Your information will be placed in a holding area for review and added to the age list after acceptance.

I am betting that the tone generator capacitors have the dry orange-ish paper tubing exterior, those would be correct for the vintage (they were the intermediate step between the brown/beige wax-coated paper caps and the red mylars that arrived in mid '64.

The serial number would indicate late '62 or '63, I was looking at a '63 A-100 #33550 awhile back.

If this is a '62 or '63, you're in for a treat..vintage is almost always bright and fat with lots of balls.

But it sounds like a late '62 or early '63 box, from what you've described. Todd in Cheesecurdistan [quote user="Blue Olive B3"] FWIW the age list is slightly off with a couple of those...fluted vibrato and reverb knobs were present on '61 instruments, and IIRC all A-100 series had pilot lights from the beginning of their production in 1959, while the rest of the console line got them after that at some point.

I'm trying to determine the year of manufacture for my A-100. Serial # 31087 Fluted vibrato knob - yes - 62 or later Small Hammond Script - Yes - 65 or earlier Pilot Lamp - yes - 61 or later AO-28 Transformer color - black - mid 62 or later RC Networks - no - 65 or earlier Brown Wax Caps - yes - 64 or earlier AO-28-5 preamp AO-44-1 reverb amp AO-39-1 main amp 6122 Leslie kit Reverb speaker # 575235 - mfd Fall 1962 35th week main speaker # 575240 - mfd Fall 1962 40th week I would say that this is a 1963 A-100 going by all this, however, the oil chart in the bench has the first entry as 1961. I cannot guarantee this bench came with this organ originally, but it looks like original: it's an A-100 bench, and matches the organ color.Another alternate is in the format following: 188-5 69 32 188 is General Electric.
