Asked by Anonymous on April 6th, 2018.
This part does appear to be the equivalent of the Fender part 16282 from all of the info we could find.
1 answers Does it matter if it is installed silver dot face up or face down? Or it doesn’t make a difference?
Asked by Anonymous on August 15th, 2018.
This optocoupler can be safely installed with the silver dot face up or face down. The dot represents the non-polarized side, so pay close attention when installing this part. Installing with the silver dot in the wrong direction can result in damage to your amp.
1 answers is this ok for use in a 1965 deluxe reissue?

This is the second LDR that I have purchased from Antique Electronic Supply and it, again did not disappoint. This is the best and only solution that I have found to replace a defective original Fender LDR/neon light combination used in Fender's vibrato circuit. These work great and I have noticed that this LDR has both ends of the black heat shrink encapsulation to prevent external light as well as any contaminants from entering.
Great part, larger than original in my DRRI but works fine. I still had the ticking after I installed it. After reading a lot of posts on various websites I came to the conclusion it could be my wires. I opened up the amp and removed the guts so I could hear the tick and buzz as I probed with a wooden chop stick. I moved each of the blue wires on the different tubes and found the culprit and the ticking stopped. Hope this helps someone. Be very careful if you try it.
I put one of these in my 65 Deluxe Reverb reissue. It quieted it down considerably. I think I'll also add the .01 mfd cap for good measure and be done with it (as per The official Fender solution (Service Bulletin number 9). I am glad I went ahead with this. I had repaired a few vintage Fenders but I wanted to try it on the reissue and it worked for me. I hadn't seen anyone comment on this so I wanted to share with anyone interested.
Worked great and fixed my trem issues.
Installed easily in my silver face Vibrolux Reverb. Fixed the weak vibrato and now I have a strong throb like new.
Perfect, fits like a charm. With DHL express, it was not too expensive in shipping to Norway, and the 2010 Fender Deluxe Reverb Reissue 65 vibrato works like a charm again ??
Worked great. Easy to install and got rid of the Silverface "tick"
Got this to restore a ‘69 Plush P1000S which pretty much a direct rip off of an AB763 Twin Reverb. This component restores the tremolo to rich, lush swampy throb. It sounds great and was an easy fix.
My 67 Deluxe Reverb vibrato had slowly gone out over the years but I procrastinated about fixing it. Finally I ordered this LDR and within 20 minutes the amp was running perfectly, vibrato included. I had forgotten how rich the sound was on this amp prior to the and finally I can play songs l crimson and clover again. Lol. It is an easy fix. After removing the old ine simply solder in the silver dot side towards the 12ax7 and the other side towards the resistors and your in.....that simple
