So, I've started my SLO-build by ordering PCB and chassis.
When i start ticking of parts from BOM I'm a bit confused regarding part prices and availability. I know it says "...indicative only..." but that's not really true i think. Some posts are a bit higher but on capacitors and resistors there are really big differances. Since revision 1v1 is from 28 september this year i assumed the prices/recommendations were reasonably up to date. Can I search other parts based on values or is there a reason you listed parts in BOM?
Examples:
R36 | 82k | Vishay CCF60 | CCF60-82.5k | Bom Cost: € 0.08 |Mouser.co.uk: € 1.61 |Difference: 20x more expensive
R9 | 1k8 | Vishay CCF60 | CCF60-1.82k | Bom Cost: € 0.13 |Mouser.co.uk: € 1.61 |Difference: 12x more expensive
C11 | 1uF/100V | Mallory 150 | 150105J100IC | Bom Cost: € 0.92 |Mouser.co.uk: € 3.50 |Difference: 3x more expensive
C6 | 0.022uF/630V | Mallory 150 |150223J630DB | Bom Cost: € 0.51 |Mouser.co.uk: € 2.12 |Difference: 4x more expensive
J1| Shorting Mono Jack | Switchcraft 12A |502-12A | Bom Cost: € 1.03 |Mouser.co.uk: € 3.65 |Difference: 3x more expensive
These parts are listed as Obsolete/End-of-Life:
R - 2M2 | Xicon – metal film | 273-2.2M-RC
R - 1R/3W | Xicon – metal film | 283-1.0-RC
R - 220k/1W | Xicon – metal film | 281-220k-RC
R - 10k/3W | Xicon – metal film | 283-10k-RC
R - 15k/3W | Xicon – metal film | 2283-15k-RC
R - 1M/1W | Xicon – metal film | 281-1.0M-RC
R - 100k/1W | Xicon – metal film | 281-100k-RC
C - 220uF/350V | Nichicon UPW radial | UPW2V221MRD
C - 47uF/100V | Nichicon UPW radial | UKZ2A470MHM
C - 447uF/450V | Nichicon UPW radial | UPW2W470MRD

Hi Andrea and thank you for the reply.
I think you don't have to provide the pricing at all. Links to the products that you recommend is plenty in my opinion.
On another note. In the SLO-100-LDR, shouldn't P4, P9 and P10 terminals #3 go to ground? I am a total noob when it comes to electrics but better ask I think.
