I believe it should fit right on the PCB as it measures the same as the Digikey part. Please someone correct me if I am mistaking!
Also for such a beauty, I would like Gold plated RCA output. I got these 806-KLPX-0848A-2RG
(Red One) and 806-KLPX-0848A-2BG
(Black One as the White is non stocked... There's also a Yellow one 2YB).
Finally I wanted a more precise time base and came up with this 815-ASV-12-EJ-T
which is 20 ppm instead of 25 for the same price. Well this is really over the head...
For those interested I have the project ready to be shared on Mouser, but I am probably not the first one to have it in the starting blocks I guess...
Overall it's 73.98 USD including standard Hammond enclosure in Silver (13.08) and an extra Opamp OPA2836 (3.71 USD). Without these we're good to go for a mere 57.19 USD (!), once we get our custom case from Beezar. Overall it's 120 USD as shown in the BOM (45 USD for the custom Case, 10 USD for the PCB and 5 USD for the custom screws).
For such a price, I think this is going to be a HUGE success!!
I also may consider switching the red LED for a violet one just to keep the color in tunes... Ehehe...
It appears that you are correct about 806-STX-3150-3N. It must be new, because even the Mouser salesman couldn't find it for me a month ago - only a 5-pin version. If it checks out completely, I'll add it to the Mouser side of the BOM.
Gold RCA's look really fugly with a blue case and white-silver laser-etching. Silver jacks were selected on purpose. Keep in mind the silver RCA jacks are plated nickel, not tin.
Cobaltmute will have to confirm on the oscillator, but we knew there were substitutes.
Remember those blue-anodized aluminum screws include my tapping the case for 6-32 threads. Being aluminum, those screws will strip if the case is not tapped. The normal screws that come with the case are regular 'ol silver phillips self-tapping screws.
The total price of the kit will be $125 - you're forgetting to add in the 806-STX-3150-3N on the Mouser side of the BOM. Just so everyone understands, the price of the case will be $50 without the kit. There has to be some advantage to ordering it all together, after all. Plus, just to kick things off, I'm inluding both the OPA2835 and LMH6643 opamps in the first 100 kits.
Thanks for the kind comments on the website. It may be the most thoroughly detailed website I've made, yet. About the only thing it doesn't have is movies - maybe I'll add that eventually.
