So, we’ve got some confirmation for the final specs.
Large spring:
Material: Beryllium Copper C17530 38% IACS Spring upper diameter: 6,50mm
Spring base diameter: 9mm
Spring thickness: 1,0mm
Spring height: 12mm Total number of coils: 5 Plating: Copper(25um) + Silver electroplating
Small spring:
Material: Beryllium Copper C17530 38% IACS
Spring upper diameter: 4,35mm
Spring base diameter: 5,80mm
Spring thickness: 0,8mm Spring height: 10,5mm
Total number of coils: 5 Plating: Copper(20um)+ Silver electroplating
Will probably be ordering the springs soon.
Just post your interest here, and I’ll get you on the list as quickly as possible.
If needed, PM for large quantities of spring orders so we can discuss more about it.
Have you received the funds I sent you? I’ve never bought from you before and want to be sure you got it, payment message was my username, check the pm.
1. No, not optimally. You want 1x large, and 2x small.
2. Same thing.
3. Only 1x large and 1x small on the tail. No need for a driver spring change since it’s already a BeCu spring.
I did do this mod too. I’ll take a picture of it tomorrow. Fits very nicely.
4. Yes, it’ll work.
5. Yes, it’ll work
6. Yes, it’ll work quite well.
Thank you BlueSwordM, although I'm not sure about 1, 2 and 3 (A6, X6 and GT Mini).
f.e. the outer springs from the A6 and X6 are smaller (7,5mm) than the one on de GT Mini (11mm).
Also your large (outer) springs are 9mm and don't seem to fit on the contact areas provided, which is 8mm maximum for the A6/X6.
For the GT Mini the contact area is even more different as the outer springs are 11mm and resting on the same measure provided thin contact pad (same for the inner spring), the rest is purple print board, so not like the one full contact pad/circle like on the A6/X6...
Counting only on the soldering to make contact with those provided contact pads doesn't seem perfect to me and kind of misses the purpose of your low resistance springs, or do I mistake?
I’m a little surprised to see the J5 flux bin (the highest I’ve seen for 4000K SST-20s) in combination with the less green FD2 tint bin. Usually, emitters get greener as the flux bin goes up.
