Hey Terry, great video and explanation.. That makes life a lot simpler once you see how its done by the expert..More knowledge, thanks Terry..Ed..UK..😊
Works very well - just built a PR with D-Lab brass plate recommendation. Bought the brass at Hobby Lobby. ***Very quiet amp*** Drilled small holes along the plate and soldered all signal side grounds from eyelet board and pots direct to the plate. Did not solder the plate to chassis.
Extra points for creative use of carpenter's square! Good thing you're well grounded, I need a Faraday cage for my house, can you recommend a contractor? Thanks, BigT !!
Hi Terry, I’d like to know more about the science of using brass plates. Do they really quiet the amp down that much more? It would be really cool to see an amp on a scope to get a noise floor with a brass plate installed. And the same amp without one. Or maybe same model/year amp. Just food for thought maybe for a future video. Any additional info on why brass grounding makes for possible quieter noise floor would be helpful. Thanks. Love this video.
Great simple process! I've put these on my last couple builds, and in addition to ensuring you have a consistent ground, they make it really easy to attach a ground in convenient locations. Would there be any benefit to installing a brass plate to the output jacks as well to make sure they have a similarly low-impedance path to ground?
I looked it up, copper erodes aluminum, I should have remembered that, forgot that we couldn’t silver plate copper directly, have to do copper, nickel, then silver when plating waveguides to mil spec.
@@dingalarm Maybe he (R&R) believed the chassis was alu. Looks like steel chassis to me also. As a 40 year "kind-of-mechanic/electrotechie" I am courious why steel plate is not good enough. In normal conditions it will not rust or oxidize. Maybe the idea of ground plate in brass is from earlier when controller-panel-plate was not metal at all? (wood? Plastic? Bakelite(circuit-board)? Jjust guessing).
@d-labelectronics I'll look there again. I noticed weber sells the plates but not for a 65 drri. They have 5e3 and a few other circuits but not the 65 for some reason. I'll buy the shim stick and make them but i haven't found 3 x 15 or whatever it's always only 6 inches long. There's the rolls in a can. I wonder if that could work?
@@d-labelectronics the chassis is not already supplying that? Because wrong type of metal? Or brass is just better? Wouldn't insulated ground wire be better? Safer ?

You do really nice work Terry. Thanks for sharing the process…😊

NIce work, ive got a Tyler PR clone what uses a buss wire for ground and its dead quiet

Thanks for another Master Class Terry.
Thanks! Terry

@Terry, great video! One question, do you soldier the ground plate to the chassis?
He mentioned earlier that he did. He said to clean really well, beforehand.

Great idea!!
How many mm thickness that brass plate is?
Good on, thanks!
👍👍
Why brass instead of copper? Is there a reaction between copper and aluminum?
Thats what Fender used
Copper will go green from oxidation
I looked it up, copper erodes aluminum, I should have remembered that, forgot that we couldn’t silver plate copper directly, have to do copper, nickel, then silver when plating waveguides to mil spec.
A brass sheet is being attached to a steel chassis, so why should a potential reaction between copper and aluminium even be considered ? 🤔🤷♂️

Do you solder the sheet to the chassis with the schnozsaramus?
I’m wondering this too
Yep, scrape the chassis real good first. Those chassis dont take well to solder
Terry where do you order your materials? Not having any luck finding the right stuff
I find the brass & other unique supplies on ebay

@@d-labelectronics Terry will the brass shim in a can work
Terry,
Do you have a source for the brass sheet and triangle clamps
Brass via ebay. The blocks can be made out of wood
*"cleaner" as in "burr-free"
Thank YOU!
The brass plate is now waiting for ... the Nozaramus! Muahahahaha!
i don't know what the purpose is of that brass strip?
Fender designed it back in the 50's. Leo had RF engineers back then that knew their stuff! Good Tech
And what is it for? I see it. Less noise, hum. But how does it work?
It creates a ground plane, central landing area for the eyelet & control grounds.
@@d-labelectronics the chassis is not already supplying that? Because wrong type of metal? Or brass is just better? Wouldn't insulated ground wire be better? Safer ?
It eliminates trying to solder to the chassis direct, plus provides a central ground reference
Would this method of grounding be advantageous in a Champ style circuit, or overkill?
I don't understand why another "layer" of metal next to the front of the chasis make it better for the ground.
