does anyone know who they are or if they're still alive?
What name is stamped on your amp?

Iirc, D. Ledford was a quality control inspector. I personally have never seen a BF amp with a signature or a stamp of an assembler. It was common in the tweed years…name on a piece of masking tape, but those are the only amps I can recall having seen with an assembler’s name.
Also, this is the first time I have heard or read of anyone wondering about those stamped names in BF/SF amps…probably because everyone knows that those were inspection stamps…..

I have had them with a name stamped on the chassis, inside or the back. Not sure if any I have now have a name. I assumed it was an inspector.

Off of my ‘72 Silverface Princeton:

And on the inside:

In a funny twist, I was working on a buddy’s ‘72 Bassman head, and J. Castillo stamped his name in that one too!

J. Castillo and D. Ledferd are all over the early to mid 70s amps. I did some looking in to this a few months ago, and found a forum thread from a few years ago that said that D. Ledferd was still alive and that he found it interesting that people who saw his names on the old amps had been looking him up.

Interestingly enough, the pre-CBS amps 63-64, often had initials like "W.N" and "AD" stamped on them inside.

Here is a 71 Twin Reverb and a 74 Bassman Ten and a 69 Super Reverb which was the "magic marker" era of inspection stamps.

I have read some responses from D. Ledford. He stamped his name as an inspector.
Fwiw, at some point these boards in the BF/SF amps were built up in Mexico then shipped to Fender USA to be installed in the chassi.

Many of the Silverface amps had a technician# ink stamped near the power transformer. I understand this indicates the week and year the chassis wiring was completed and who did the work. Tech #22, 42nd week of 1968.P1050488.JPG My 77 DR has no such ink stamp, so they stopped that practice at some point.

My 69 Princeton has the initials "EM" on the eyelet board. at least I think those are initials. Also on the inside chassis is written "T30139", I assume is tech 30, 13th week of 1969. Looked but wasn't able to locate who tech "30" is or who has the initials "EM". Anyone know?

The 71 twin I had a lighthearted dig at yesterday in another thread here specifically says:

1969 Super Reverb: nope

Also, I got this from a very good source: The little tube chart thing? Just disregard it. It has about as much chance of being correct as being incorrect. If yours is right - it's practically a coincidence. Sometimes they would use the wrong stickers just to use up the stickers they had on hand.

Not sure if I am referring to the correct Duane Ledford, but Duane who was American and lived in Sydney, and built amps never ever stamped his amplifiers, he always signed them.

That tube chart has a two letter date code stamp…’OJ’. That amp was built in October, 1965.
It is true that tube charts can be incorrect as far as the model of amp. I owned a dead mint 1957 5F1 Chsmp that had a 5F6A Bassman tube charts can be incorrect as far it. I also owned a mint SF Dial Showman Reverb from 1968 that had a chart for an AB165 Bassman.

👆 This is exactly where they are extremely inaccurate. For dating the amp, but feel free to go by it, a LOT of people don't know any better.
I learned to date amps by component EIA codes. These dates will date the amp as well as confirm or disprove originality of major components. It is very rare to have a date stamp of a tube chart chart conflict with EIA codes ime. One time period will exhibit problems. They would be the first month of 1966 when someone failed to roll the first letter on the stamp forward from the ‘O’ to the ‘P’. This is noted in the ‘Dating Fender Amps’ articles, and I have witnessed such a tube chart in a January, 1966 pro Reverb. It was stamped ‘OA’ and had the ‘P’ correction made at the factory in just the manner that the article shows the correction.
Fender would slap an incorrect model chart in an amp…I have seen this a few times.
