Just compared them and at a quick glance the only difference I could find was the value of a bass cap changed from 47nf to 33nf. The spark definitely came first. Seems you just caught Laney with their hand in the jar.
Ha! You gyus passed the test quickly! Started drawing this and was thinking the input stage looked really familiar, And yes it was. Laney basically copied this and changed some values here and there. So this one a was a quick click and paste job...:-)
Haven't built this yet, just checking layout and schematics. Seems as if the 4.7uF (C4) on Q-R:5 is oriented opposite of the schematic in the link. Schematic for Ember (https://docs.pedalpcb.com/project/EmberBoost.pdf), but labelled C4 is also indicating the same. Not sure what impact this has.
I may try this one. I've always been curios about it. I like the little cyclone of diodes formation here.
ReplyDeleteJust curious: It is almost the same as the Laney TI Boost, isn´t it? or vice-versa...Has someone compared them?

DeleteAlso see a 4k3 changed to 4k7 - 1nf filter cap changed to 270pf ... but it's pretty obvious what happened here lol

DeleteAnd you can find used Sparks on Reverb under $50 all day and the Laney is $199. Maybe the build quality is a little better but I doubt $149 better

ReplyDelete...labelled C3 in Ember... Sorry
ReplyDeleteC11 on L-M 17 is 1uF in the schematic (same in Ember), but layout has it as 10uF...
ReplyDeleteC9 on Q-R 16 in the layout seems to be oriented opposite to the two schematics
