What circuit config is a 68/69 Trim Edge Deluxe reverb?

Cam · May 14th, 2006, 10:10 AM

What is this? An ABWhat model or? If this is on the tube sticker, mine is slightly damaged and unreadable.
Thanks in advance.

More than likely, if it's that early in the SF era, it's probably an AB763. By that time, the power transformers had been changed. So, you're probably running a 5U4 rectifier instead of the GZ34.

The rectifier is a GZ34. I think it is a very early drip edge model. I guess I should look up date codes sometime.
Thank you for your thoughts.

The earliest 68's had vertical thin black lines on the silver face too...

http://www.tcguitar.com/articles/gagliano_pt4.html
"Here's a very quick summary that may be helpful: the earliest silverface amps were made in 1967 not 1968, not all "drip edge" silverface amps are from 1968 or 1969 (they could be from 1967), not all "black line" drip edge silverface amps have the blackface circuit except for Vibrolux Reverbs, Deluxe Reverbs, Princetons, Princeton Reverbs, Champs, Vibro Champs, and Broncos."

Cam, check out the transformer manufacturer's date codes. These codes are the basis for the compilation of serial numbers in that link. You might also want to write down the model numbers on the trannies just to assure yourself of what is there. In short, copy all of the codes on the trannies and post them back here.

Isn't it on the Tube chart?

the tube chart has some slight damage and I can't read that part. But thanks anyway Paul :D .
I'm actually going to pull it apart again (maybe tonight) and do some more minor tweaks so I will check out some numbers etc.

I have a blackline SF DR. The tube sticker says AB763.

the ser. # indicates it is a 1967.

Numbers on the transformer:
025130
605 6 37

#025130--this is correct for the Deluxe Reverb. The pat number 025130 replace the original part number 125P23B in '66.
'605 6 37' 606---manufacturer, 6--1966, 37--37th week. (Unless you transposed the 5 and 6. In that case, the '5' would indicate a '65 transformer. That amp is an AB763 circuit, I would imagine.
FWIW, DR circuits never changed that much, anyway over the years. The larger amps underwent significant changes while the small amps were kept more or less the same.

As for the tube charts, they can be misleading. The early AB568 amps would carry AB763 charts that were left over. Waste not, want not was the operative thought at Fender.
Cam, your amp probably has vertical black lines on the silver panel, right?

This amp is a touch older than I thought. Cool....!
