New vero layout: EHX LPB-1

[asfastasdark]

I decided to tackle this little thing as a challenge to see how much I could fit on a tiny piece of vero.  Turned out pretty well, beating the next-smallest vero layout in the gallery by an entire row. My layout is 5 rows by 6 holes.

I don't think I did a very bad job, it took some rearranging and thinking... but I have concluded that making layouts is fun. Lots of fun!

Nice layout! Is it verified as of now?  Might you know how the LPB-1 varies from the LPB-2? I have a Fetzer built and i am looking to compare a few different clean boosts. Any thoughts are appreciated

forgot about checking the "notify me of replies" box

Same circuit. The original LPB-1 was a plug-in box and the LPB-2 was the stompbox. Now the stompbox is marketed as the LPB-1.

is it verified now? I'm going to make a lpb1 in an A enclosure, so i'm very intrested in this small layout

I just did a quick check of the layout against the schematic and it seems fine to me! Personally, I wouldn't hesitate building it. And its such a small circuit, so even if it has errors, it doesn't take long to rebuild.

I just built one from this vero layout and it works fine

i know i'm a noob at building stomps, but how do i wire it up to my 9v, switch and pot?

thnx in advance.

Yes I as well would like some information on wiring up to this same Vero I've already built.  I've build a few clone kits, so never had to figure out how to wire these things up to the vero board.

Finally found what I needed digging around.  Here's a link for anyone else like myself.

Have put this together and i have no power or anything to it.  Getting my hands on a DMM asap to troubleshoot properly. 
My switch wiring calls for lug 1C to go to circuit output, is this the same as "volume 3"?

[duck_arse]

"circuit output" to a volume control will usually (always, no exceptions) go to hot, or CW, or clockwise. ["3" is basically meaningless.] from a volume pot, the wiper or W or centre lug will be the most useful point to send to the switch, thence the outside world.

if "volume 3" actually refers to CCW, and is grounded, then "lug 1C" may well be used as a LED supply connection. I'm probably not helping you out at all here. once you work out why the lugs are named as they are, it becomes clearer where they go and why.

[I tried, I followed your link, but as usual, I went around and around in circles clikking links to the page I was just at and ended up without any wiring diagram. I'm not keen on tonepad pages.]

well now you have me confused. I see no volume 3 anywhere. are you adding a vol pot, or is the a vol pot not being shown on the dia?

Volume pot on the vero layout.

Where it is labeled "Volume 3" is the output of the board, and goes to the "hot" lug of the pot.  The other outside lug of the pot ("Volume 1") goes to ground.  The middle lug of the pot ("Volume 2") is the output of the total circuit and goes to the foot switch and output jack after that.

[eugenious79]

Ok i had the switch and the pot both wired directly to the circuit.   I have changed that and looked over my soldering.   Now im getting a very dim LED, with a low volume high pitched squeal that the pot will control. 

Managed to get readings off R3 (390ohms) and R4 (17k?).
Transistor voltages are
C- 9v
B- .75v
E - .15v

I made a wiring error on the switch early on and during replacing wires, lug 1A has become loose and pulled from the housing.. also happens to  be the lug the LED connects to.  But im getting continuity between 1A and 1B.. so the switch is ok still i believe.

the switch can only be considered ok if all three poles throw consistently and reliably when you push the button. one lug missing - you might be able to work-around, but it likely points to "other problems", within the switch or without.

if your collector is 9V, it would indicate the collector resistor is shorted. the collector needs room to move up and down, so ~5 volts on the collector is a good start.

[thermionix]

if your collector is 9V, it would indicate the collector resistor is shorted.

OR that you have no current flowing through it.  Just sayin'.

Lol, if this hasn't been verified by now, I built it tonight and it worked fine.
