Thanks again. Within that footprint series there are lengths of 25.4, 38.1 and 50.8mm tall. I suppose 38.1 is a good compromise for shedding heat and clearance in a low enclosure.

if you desice to built the preamp with the slim case then use the 25,4 hight.
i prefer the biger one. 50,8 and even the 63,5 (i have stock for my projects)

Huh. Just checked: 24,416 in stock. Maybe it’s not for you Aussie’s. I guess Arrows not the cats meow for all.
They usually send to Oz no problems. I see 21k units in stock too. $1.37 is a great price for a Fischer this well made.
That is weird as I am just clicking the link in Tbone AK's post and it goes to their webpage for the SK104 25 and it says No Stock Available. However when I look via their homepage and search for the item, it then shows them in stock as you state. Using Firefox for that search and Windows IE for clicking the link in the DiyAudio forum, may explain this!!
Seems the Fischer stuff mainly ships to usa from europe, possibly subject to fees, tariffs, etc. at time of delivery as indicated at checkout.

Ok, the RCAs JP spec’d out are snazzy. But this seems to be a re-occurring procurement issue. Hifi Collective might have them, maybe, google search says yes, but not by search on their site. In the Aska Leader 40ppv thread, it was partially addressed but faded out a few years ago. The CUI alternative will certainly work, but the one JP specs out are nice and stout looking. They seem to be the right option for the awesome case he and his wife have designed. I think X has looked into this, but he likes his audio naked. That won’t fly for me, WAF and BAP (Budding Audiophile Proofing).
GB if we could source them?

BAP was referring to my kids. They’ve taken an interest in this hobby. Twist and pull, the connector, STOP! Grab the connector, stop pulling on the cable.....
Hello TboneAK,
the RCA CINCH audio connector used is one of the best for the price I´ve found.
I´ve buy them at Audiophonics.
Today 17 YARRA builder so in sum 102 red and 102 black RCA CINCH!

JPS, are you suggesting that a deal could be done if you source these RCA connectors?
I had a look at their website and they list a lot of RCA sockets, but none under the brand Cinch. What is the Audiophonic reference number for the actual ones you are talking about?

Same here with “Cinch”. I found these on the Audiophonics site that look like the ones in JP’s case drawings.

I’ve been looking over the Yarra BOM that X posted in post 71, to start getting the odds and ends sourced. It looks like a lot of those are euro sourced items. The RCA’s and heat sinks are some of those. Arrow has the sinks and KSA1381’s, parts connexition has the pots, Mundorf oil caps, and shaft kit. Transfo’s from Digikey. This is quite the build, not just an easy peasy mouser bom.
At this point I’m not inclined to short cut anything on the first go. Start with the HPA set-up, which should drive my current cans and the F5T. Then start playing around once the M2X and new Spk’s are built.
Thanks for all the great help, X, JP, Vounce, and all!

I was able to get the Fischer heatsinks from Mouser. You have many choices on the pots, and I am just going to use a basic Alps RK09. Although, Vunce said he has a fancy stepped attenuator he recommends. I am also working on (my spare time) an Arduino WiFi controlled digital volume pot. That might be interesting. Also, truth be told, I frequently use a $12 Bluetooth receiver with a built in remote as a source for my Class A amps. To all but the most discriminating uses, it works fine with BT 5.0 - sounds lie a hard wire connection. Has track select, pause/play, volume, mute, etc - seems to check all the boxes as a source for the Yarra.
Hi X,
The pot is probably not fancy enough for this project, lol😀

I am using the basic Alps RK09 10k for the initial setup, will change it when the Yarra is put in an enclosure.
Right.... When the Schurter IEC power entry module/EMI filter and fuse holders costs $35, you have to spend more than that on the critical volume pot! 🙂
But hey, JPS64 spec'd the best medical grade IEC possible - it is built like a tank and as nice filters complete with measured noise reduction performance. How often does one see performance graphs for an IEC power entry module? I am glad I got it - as it fits on the board and the casing.

Hi X,
don´t forget some spare control lines for POPI! Unfortunately very busy the next months. So progressing very very slowly.
If all gones right I´m probably in May for two weeks in China (PCBWay producing PCB and equipped PBA for CPU/GPU mission computer mainboard prototype). I´ll ask ELECAUDIO for quotation for red and black RCA CINCH connector.
So, I´ve to look at Lorlin switch definition and verify the EAGLE definition.
