Lightspeed pcb

Hi Oliver,
Sorry to be a pain in the A!

I'm a bit lost about how to order and pay for a pcb for George's Lightspeed - I see that all the confusion has been sorted and the 3rd group buy is proceeding quite well (thank goodness)

Could you advise, please - James Hill (jameshillj@optusnet.com.au)

Oliver,

got my boards -thanks. I also want to publicly thank george for his wonderful innovation and his sharing of this with the community. I think its a class act, and i really like the fact that oliver has printed on the boards that this is george's idea and innovation. Pure class in my opionion and i would like to publicly recognize both of you for this.

thanks a bunch, i really appreciate your selfishness and willingness to share your ideas and labor with the common man!

Hi dvb-projekt,
Can two boards be wired together for use with balanced audio? Maybe together with a quadruple log potentiometer.
Also, do you know how much current is drawn from the LM7805.
Thanks,
Nic

parts list.

I had a great experience ordering my boards from both Oliver and Farnell in the UK.

I bought enough parts for three units (for my active xover) and it arrived in just TWO days! all the way from the UK to my remote part of Northern CA (everything takes longer getting here).

https://export.farnell.com

Qty - Part Num. - Desc
10 - 1006004 - MKS02 0.1UF +/-20% 63V CAPACITOR, 0.1UF, 63V 85322500 MKS02 0.1UF +/-20% 63V

3- 1102157 - LM7805CT V REG +5.0V, 7805, TO-220-3 85423990 LM7805CT

5 - 1165340 - 2222 037 58109 CAPACITOR, 10UF 63V 85322200 2222 037 58109

3 - 1227603 - CP16DH10IP6103BF POTENTIOMETER, 10K LOG 85334010 CP16DH10IP6103BF 15 -

15- 1283526 - 236-402 TERMINAL BLOCK, PCB, 2WAY 85369010 236-402

6 - 9608591 6 6 0 M64W102KB40 TRIMMER, 24 TURN 1K 85334010 M64W102KB40

12- 1562602 - CCF55100RFKE36 Metal Film Resistors; Resistance:100ohm; 85331000 CCF55100RFKE36

All in all it came to about 36 dollars, something like that.
