Tech Help - Projects Page / Re: Afterlife Debugging
June 17, 2012, 12:31:20 AM
I just finished the afterlife build and wanted a little more comp, so I put a couple 1N34 in reverse parallel from vol lug 1 to vol lug 3. It did a little, but not enough so I increased R4 to 47k. The R4 change really made a difference. It gets pretty skanky if the sustain is maxed and you're picking hard with high output pickups, but you can still turn down the sustain if it's too much. It definitely got more comp out of it though. I dig it now. I don't know if it will cause the Vactrol to die faster though. I guess I'll find out.
Hope this helps some folks.

That was it! Good eye and thanks so much for taking a look and helping. I guess there is such a thing as brown-black-gold-gold. No idea what it means though. Do you know? I put it on the meter and it wobbled bettween 1.3 and 1.5 ohms.
Anyways, thanks everyone who took the time to look and offer suggestions.

Yeah it looks like brown-black-gold-gold. Which doesn't exist that I know of. (My other yellows look yellow, not gold) I'll swap it for another one that I'll check with my meter when my kid takes a nap just in case.

Can's tab is on pin 8

Here's one side. I'll get the other as soon as I can get the pots off.
Mods are C8 now two .0022 in parallel
C12 now 1uf (didn't change this on the other board and it has the same problem)
multiple diode changes (they worked on a RAT I modded)
used UA308HC (small bear said it worked the same as LM308)

trying to shrink the photo file size to 1000kb. Do you want me to pull the pots off the backside for that picture?
#7
Suggestions anybody?

That's not it either. I just checked. In fact, I had socketed R3 in one of them and toyed with it prior to asking for help. Currently R3 is 1M and R11 is 100k, but no love. What would I change in the power section to drop the votage of VC? It's high on Q1 as well as the IC (right?).

They are 100k. Brown/Black/Yellow.

Tech Help - Projects Page / Slow Loris Bias off I think
February 11, 2012, 12:28:31 AM
My Slow Loris I built is not biased (I think) properly and I'm not sure what to change. When I hit a chord hard I get sound that doesn't sound great. If I push a pedal in front of it turned up it works great until it decays then gets weird again. I built two at the same time and they both do the same thing.
Here the voltages
308 IC
Pin1: 8.71V
Pin2: 8.74V
Pin3: 8.45V
Pin4: 0
Pin5: 4.2mV
Pin6: 8.83V
Pin7: 9.43V
Pin8: .1mV
2N5457
Drain: 9.43
Source: 1.173
Gate: Never stabalized and I got tired of waiting for it to stop slowly dropping.
