Don't waste your money on RCA Jacks. Just get these Manley Labs Jacks for your WOPLs and the WOA Model ONE:

MANLEY RCA Gold-plated & Teflon phono jack Brand NEW!

If that price ($1.99) is still good, it is a steal.

I would not use a $1.00 RCA on a $3500 amp. That's how the fuckin Bean Counters ruin shit. Same reason I don't repair/restore the PL400's and 700's. They get FULLY WOPL'd or they get ran over with a 4WD. I don't like to worry every time I hit the power button after spending buttloads of time and money doing the best I can. The preamps, we don't have a lot of options on so I keep at it until I'M satisfied that it's the best we can do. If we had the option of having new boards and chassis' available, I'd spring for the parts.

That's probably why my credit card balance creeps up until the Ol Lady kicks me in the groin............ :)

$1 RCA with 100% Oxygen Free pig iron..................... Not my cup of tea. You guys put the cheapest parts you can find in a world class Model 1 or a WOPL???? Now that's funny. When you build mine, I'll fix it properly when it shows up on the Fedex truck.
 
The guys doing the reviews for the Manley Jacks are fucking high. Those are NOT the best in the world, they are just cheap bastards. I actually have some in a bag but I won't use them on my shit.
 
Here is what I used on my WOPL's but they are not always available.


Cardas GRFA L RCA, Sonic Craft

The GRFA L (inside chassis mount) female RCA is machined from a Copper rich (>75%) alloy. The Teflon dielectric along with the Rhodium over Silver finish assists the clean/fast signal transmission that the GRFA is known for. There is no audibly superior chassis-mount RCA at this price point...

Tubes??

Actually Joe, it's a tube Preamp. I built one for my friend out in Indiana and after I tore it apart a couple times till I got the grounding scheme correct and it sounds really nice. So, after listening to it on a couple of his WOPL's (I built him about a dozen 700B/700 II/Claire Bros/ and Pro 700's and it sounded so sweet and quiet that I decided to build one for myself. I'll take some pics when I get these 2 C-4000'a finished. Mine will be pretty much the same topology/design but mine will have some bling to it. Tubes (eight 12AY7's) sticking out of the top and have some woodwork embellishments in Mahogany The gain was too high and resulted in some of the hum so we got a set of gain matched,12AY7's and pulled the higher gain 12Ax7/12AT7's, replaced the transformer to a larger one and it was great after that and all housed in a PL DRS-400 chassis painted black being in-COG-Neeto......

Manley Labs makes and sells these RCA Jacks for $7.00 each. This other company must have bought a bunch and now wants to liquidate them, no issue there.

Manley Labs makes the highest-rated Studio Recording equipment in the world, so cool your jets, Perry.

Manley Labs RCA Jacks are made in-house in California using 100% Brass and heavily plated in Gold with a solid Teflon insulator that will never melt. They just happen to fit Phase Linear amplifiers better than metric or other imported RCA Jacks.
Cardas (Sonic craft) says "machined from a Copper rich (>75%) alloy". That would be brass, just like the Manley Labs RCA Jacks, but more marketing rich-sounding words.

Cardas also says "There is no audibly superior chassis-mount RCA at this price point" That is likely true because they cost $82.00 a pair; and that puts them in a class all by themselves.
By the way Rhodium has a conduction rating of 22.17x106 while Gold has a conductivity rating of 42.55x106, almost twice as conductive.
This is the case in the most conductive metals, such as silver, gold, and copper, who each have a single valence electron that moves with little resistance.

Chase the hype and the fancy terminology, I will keep using Manley Labs RCA Jacks and I bet you your Harley that you cannot measure or hear the difference. But the Cardas Jacks are good for bragging rights. Such as "the clean/fast signal transmission" what does that even mean?

I don't put down anybody's choice in their parts selection - until they put mine down. I didn't ask for any criticism, and I can take it, as long as you know what you are talking about. In this case you do not.
 
Rhodium is much harder than gold. Naturally lubricious as well. Used often as plating to higher end wrist watch movements. Also (not relevant here) higher thermal conductivity than chromium. I wrote IP to use Rhodium plating in place of hard chrome plating for nozzle bores.

Cool YOUR jets Mark, you and your buddies got the best possible RCA Jacks in the world all for $7.00. Keep telling yourself that. If they were, you'd think they would get at least $8.00 for them. Your gold plate is so soft, it will be long gone before the rhodium pig iron.

Perry, where do you get this nonsense? I have Manley Labs RCA Jacks on both of my PL400 Bench Mules (one for testing WOA Quasi Comp Control Boards and one for testing WOA Fully Comp Control Boards). I have assembled and tested about 60 WOA Control Boards, so each jack gets inserted and removed twice per test, before and after. There is no wear on the Manley Jacks after more use than any RCA Jack will see in its lifetime.

It took me three years to find the Manley Labs RCA Jacks, you think I just tripped over them? When I saw them on the Manley Labs recording studio equipment, I asked the owner, EveAnna Manley, if I could buy just the RCA Jacks from her. She said OK and gave me a good price. Why is that so offensive to you? The new owner, Dirk Ulrich, who bought the company on July 10, 2025 may still make the RCA Jacks available to folks like me who appreciate a quality part. The company is relocating but should re-open soon.
 
Perry's just grumpy.

I agree with him in principle- don't cheap out on a component where you have many hours and dollars invested otherwise. On that we are in complete agreement.

But I'm a stingier bastard than he is, so I appreciate a deal.

Finally, empirical testing trumps opinion as well as decent calculations. You have the empirical data they are decent. Relax knowing you saved enough for a six pack and crack one open (and send me one too!) "In God we trust; everyone else must have lots of data."
