I have used a Denon desoldering gun to remove displays and IC's for decades with no problems with foils. Your method is admittedly much cheaper than buying the gun, and what I used to use before buying it. Of course, I was an electronics repair contractor for many years, and time= money. Nothing wrong with your method, but folks should understand there are other tools to do the job. Most excellent cleanup of the circuit board. It looked like new.
It's good that the designers of the circuit board made the plated through holes big enough to re-work relatively easily. All too often you see the holes just big enough to accommodate the component leads and then you can have problems cleaning them out if you don't have a desoldering gun.
Old school is in session! Turn board upside down like Terry did. Get some rosin flux and wipe across the remaining pins. One by one take a soldering iron with a chisel tip and heat and push down on the pins. Some may just drop as the flux won't hold them but you can pull any that won't fall through. Clean remaining solder covering the holes with solder wick and heat . Then follow Terry as he puts the new display in. Do all steps carefully you're not in any kind of race.
I've done similar repairs, cannot agree more on the requirement to take your time and methodically work your way through it as you demonstrated. Like others, I'm curious where you found a replacement display tube. I've seen similar but for something like that you need as exact a match as possible. One of my pet peeves is trying to find replacements for special parts like those. Keep up the good work, Terry!
I would recommend a Pro'sKit desoldering station, cheap and that gun makes desoldering soo much faster and easier. Powerful pump in it too. There is some good youtube videos about it.
Hakko 808 (not expensive) or a hot air station (slightly more) would make quick work of that. I used to do much larger displays on pinball machines. The most fragile part on those displays is the legs. Doesn't take much flexing to snap them right off.
I hate getting pins out of pcb board,it always takes me so long. Its tedious and you gotta be so careful, you don't over heat the board and burn off the solder pads.
I know I sound like my grandmother but every time I watch this channel or any other "amp repair" channel I am amazed at how dirty the stuff is that people send in. Would it kill you to at least dust off the outside before you send it out?
Terry, would you please remind me of what model you magnifying lamp is? And I know you were in the Air Force, so were you ever stationed at Vandenberg AFB? I bought some Chemtronics solder wick and you were right, it is excellent stuff.
I just bought a Rocktron Intellifex V1.11 that sounds great, but it has a display that has a brightness intensity of only about 5% to 10%. When powered on, the jelly bean cap leads meter at 28.8 volts, so a replacement display is probably the fix. Do you have a spare one that you could sell me, or can you quote me a price to do the repair? Thanks in advance, Tony D.
I have a voodu valve that has a bad selector dial. It will skip over ever other preset so im only getting about half the number of presets thats avaliable. Is it possible to replace that part? If so where would I find a new dial?
@@d-labelectronics Hello, great video. I have a Rocktron Xpression. I thought maybe I had a bad display cap, but I don't have the 28 volts you said should be at the cap for the display. By chance do you know where the source voltage is? Thanks. You also helped me fix my Egnater.

Nothing more interesting than watching an electronics surgeon!

Keep up the good work, Terry!
Nice Job Terry !!! We know you can fix just about anything.... Well done and nice little "7" amp..
That was really different to what normally do - but you fixed it. Always enjoy your videos Terry.
Hey Terry, nice to see a different project..! Very intricate little job, great video and top tech tips..Great job..Ed..uk...:)
Nice job, doc. It Lives! Nice video.
I use silicone tube heat from the bottom and blow it works much better than braid
Too cool Terry. Thanks for your tech tips and idea's. Your the best 👌

Thanks Terry . That amp 7 is going be sweet
You're just like a surgeon 👨⚕️

Have you ever tried Chip Quick? It uses less heat, keeps all the connections liquidous and cleans up quite well with solder wick.

What a beautiful device!
Flawless Work! Terry where did you get the replacement fluorescent tube from? Have a most awesome weekend!
The Nutube is based on VFD technology. It might make for an interesting amp project.

Hello Steve, Yes Sir, it will be cleaned before leaving the shop

I would definitely replace the Tantalum capacitors - sooner or later, they will die anyway.
how did ya get a replacement?
Where did you source a replacement VFD from?

where the hell can I get a few of these VFD Screen's?
If I remember right you worked for Rocktron Terry?

Where are the fluorescent tube sourced?
Content suggestion...finish about four or five of those glasses of wine THEN do the repair. Just for contrast.
Pulling teeth at DLab Dental!
Same display type as a Motorola Spectra/Astro Spectra/XTL5000, just longer...
Where did you get that display tube from?
Old stock, had it in the shop
@@d-labelectronics - nuts! Have been looking for a source for various tube displays
