What EXTRA parts do you have or need?

[Beaker]

This one is kind of like hurling yourself down a BMX ramp, determined to pull off a double back flip with a 360 spin, a week after learning to ride a bike - it's gonna end in tears.

If you start off with a hundred transistors, you might only find ten that measure in range - if you are lucky. Of those ten you might only find one that sounds right - if you are lucky.

Everything that Zach and Travis says here is true. I've not even attempted this one yet, just too intimidating, and I don't have anywhere near enough transistors to play with to get it right.

This is why I tried to gently point you in the direction of the Green Giant / Germanium Giant the other day. Super simple, proven to work and sounds great. As I said, you can learn an awful lot from one of these, a Fuzz Face or a Tone Bender.

Hope this helps.

Well, thanks to everyone. Good to hear, Rocket.

It's funny because I have done a lot of very complicated circuits here, like JCM800, Thor, Sabra Cabra, compressors with LDRs, or the Diesel Diefet with 7 pots and five bias trimpots - and on some of those if you don't have everything perfect (like no pots wired backwards, etc) it won't work at all until you figure out every issue.

And I have built several different germanium builds now, including a couple a fuzzes with fairly low component counts. I have not done a fuzz face or tone bender yet, just because I saw other builds I could do faster. Some whose names I don't even remember but they all worked. Crimson Drive, EHX Germ Overdrive, I think I did the Monolith Fuzz Oracle,  Travis Axial Rangemaster, and a couple more - all worked.

I looked at the Green Giant but it doesn't specify a Ge, just a 3904, so I chose to skip it. I did other silicon fuzzes in the past when I first started.

I guess it's obvious I haven't always read the deep background on every circuit. I generally just look at the layout and BOM and see if I have all the parts. I missed the text in the EHX OD that said I need PNP Si transistors.

This one looked easy - but up until now the success factor on almost every circuit for me has been black or white - if I build them right they work, but if I don't they don't work. I have never heard of one where you have to go beyond the part number specified to find the exact perfect part attributes. I have seen it discussed (of course) but with my FET builds it was never that critical (that was my experience - I know they say you have to match forward voltage in some circuits, but I never had those issues - my builds generally worked. I also have almost every major kind of FET out there now, so I am not substituting FETs)

So - this is a new wrinkle to me. i would like to hear a working one.

The fuzz oracle is fuzz face based. I still recommend the Buzzaround as a great build for you. The ARC B1 layout on the main page includes a charge pump

Here's how the FZ-673 is supposed to sound http://youtu.be/xNFMAnkuAqw

The thing about the Germanium Giant is that the original Green Giant is just the 3,000,000th Electra (this time with a neat saturation control), and we'd discovered that it sounds great decked out in all Ge (transistor and diodes). It's a super simple and friendly build. I'm going to build one myself. It's for this reason that it's a good starting point for experimenting with germanium, as it's forgiving of imperfections unlike so many of the fuzz schems around here.

Where is this Germanium Giant? I searched for it but do not see it.

It's in the contributions section oster as the green giant. It all started with my layout for the green giant and spiraled to the Germaniun Giant, and apparently I created something else from it and nasty had made a layout from my idea all posted in that thread.

There are many builds that are not plug and play. Most of the FET builds, as frank pointed out, require choosing the right FETs, not just insterting and adjusting a trimmer for bias.

[Beaker]

There is Mark's layout on the main page:

http://tagboardeffects.blogspot.co.uk/2014/09/nick-greer-green-giant.html

I suggest you read the comments first.


Then it moved over to the "Contributions"  - "Layouts" page, with several different modified versions drawn up by Zach.

http://guitar-fx-layouts.42897.x6.nabble.com/Greer-Green-Giant-tp13051.html

It turned into a real collaborative effort!

Note - I am moving my comments over the the

So this thread can get back to its original message.

Okay I've got:
20xIT308B Ge trans(pnp)
20xsfd112 Ge diodes
20xsfd106 -"-
40xD311-"-
40xD18 -"-
Also:
70x 2n5401 Si trannies(pnp)
70x 2n5551 Si trannies(npn)

I'll split down to 5's or 10's
these are up for swaps(can't be arsed messing around with money)

Email me if you're interested in anything and tell me what you've got to offer
I'm particularly interested in the D9 series of Ge diodes.

For the price of a stamp-what the hell.

[Silver Blues]

I'd be willing to trade some of my 1T308Vs for other germanium transistors if people are willing.

[motterpaul]

And I have AC125 Ge Trannies.

Silver, I would trade both of you 10 each if you want (or up to 20). I am in AZ, so it is just a matter of regular postage.

Bogey: I have the AC 125s, or a lot of great mic 470p caps, (they are huge) if either of you are interested on those.

I WILL GIVE YOU:

30 AC125 and 30 470p for

10x fd112 Ge diodes
10 sfd106 -"-
20 D311-"-
20 D18 -"-

[Silver Blues]

EDIT actually no I changed my mind. I'd straight trade you 10 1T308V for 10 AC125 if you're ok with that.

I also have them catalogued by gain and leakage so if you're looking for a particular spec let me know.

[Travis]

I've got a LOT of these



They come in sealed bags of 100 pieces. They are 4n7 film caps. High quality and "mojo"

[motterpaul]

 I have 150 ac125s so I am good with whatever in small amounts. What kind if HFEs do you want, they tend to come between 100 - 200. I would want lower of the IT308Vs (for variety)

I can add to my previous offer to Bogey, too. Maybe some PT2399 with 5V regulators.

[motterpaul]

Travis - I saw those - do you want to sell any? I don't need 800, but I would take 50 to 100. I would trade for smaller amounts.

[Travis]

I would prefer to trade. They come in sealed bags of 100

[Silver Blues]

hFEs aren't terribly critical to me, but definitely something higher than what I have would be nice (which is kind of a given lol). Perhaps like 110-130 range would be nice. I'm not at home right now but I'll check my spreadsheet on Monday for you. IIRC I think I've got low 30s to high 40s with excellent low leakage (most under 25uA) at 22deg.

[bogey]

Yeah i'll take you up on that offer Paul
Not in at the moment email tomorrow
Cheers (i'm in the pub)
:-P


Cheers (I'm in the pub):-P

[Silver Blues]

Paul, I've got 31-46 hFE and 13-32uA leakage. Anything in particular you'd like or is anything fine?

[motterpaul]

Silver, I would like some of each, some low hFe and leakage, and some in the upper range.

Bogey - sounds good to me. We will work out the details once I get some work out of the way.
