Mic is not responsible for the content, just the collection.Fender Fender Transformer Codes From BREME–(at)–Sat Jan 13 CST 1996 Article: 77538 of rec.music.makers.guitar From: BREME–(at)–(THOMAS BREMER) Subject: RE: Silverface Deluxe Rev Questions Date: 13 Jan 96 -0800 References: Newsgroups: rec.music.makers.guitar Organization: The Microsoft Network (msn.com) Lines: 34 Heres a quick way to date Fender amps (’60-82).I saw the thread about the guy who wanted to date a Vox so I thought I'd come clean. For the hard to reach places and really dirty spots I used a toothbrush. For her knobs I applied just a bit of contact cleaner. She had been off and in standby for quite awhile, so I decided to not to fire her up right away so I could get a better look first.She was a bit on the old side but very mature and she had lots of mojo. I also noticed that her valves rattled a bit and I was obviously concerned with this.Beware of someone trying to sell these to you as a "blackface" amp.They are decent amps, but not really what is generally known as "blackface"!Comes equipped with Celestion Speakers (V Type) for a more modern, punchy sound that breaks up nicely when pushed.

The only good thing about dating amps this way is Fender never deviated-still valid today. If your JBL says D120F on it(look for the “f”) certainly could have been stock.

AA763 was the first circuit that Fender used and didn't last long.

Soon after the circuit became the famous one, the AB763. Amps such as the Pro Reverb (AA or AB165, came out in late '64) and the Vibrolux Reverb (AA864, came out in late '64) are identical to AB763 circuits and are still considered the "good" ones.

View the underside of the chassis (flashlight helps alot)look for the reverb driver trans.

Its in the middle of the 6 preamp tubes with the removable shields. For a black face, this transformer would have been made in 1964 during the 23 week (—423) The trick to this is they don’t renumber the decades.
