I want to build brown sound i a box but I cant get
J201 Fets here in this part of the Philippines.
can J202 be a direct substitute to J201?
will it makes any sound difference?
On and off ratings are higher and more widespread on a 202, but otherwise theyre similar. Most small-signal FETs should at least work - although you might have to tweak a resistor or two.
Get them and stick em in, see what happens. Start with a simple single stage booster, so you can really see what's going on and not get flustered by a lot of components.
hih
It will sound different.
The J202 has a higher transconductance (double that of the J201), a wider range of Vgs(off) and a higher zero G-S voltage drain current.
But it will probably work, if not order the J201s.

im pretty sure Steve from Small Bear Electronics will ship J201's to you!
Even living in the US, I cant buy them locally. The Rat Shack stoped stocking them some time ago, or so i hear....

Please be reminded that I live in a third world country where
ordering online is considered a luxury.
Maybe someone can ship me some for free...nah I'm just wishful thinking.

someone is doing me a favor, so i will pass it along.
as long as i can fit them in a letter sized envelop, i should be able to just throw a couple stamps on there.... where do you live anyways???? PM me
"someone is doing me a favor, so i will pass it along. "
I love this place :D
Hey crawler486
Im from th Philippines too!!! so I know what you mean. We just have to be extra resourceful hehe.
Ive been substituting J202s for J201s and i havent experienced any problems. I mean they seem to react to biasing in the same way. Havent heard any difference.
I get my Jfets from alexan. theyre 35 bucks a pop
Wheres your part of town? Maybe we can hook up and play through some of your stompboxes?

That is 63 cents USA, before anyone faints :wink:

Yeah, that's right. It is actually 35 pesos, not $35 as others might think. P56 = $1. Crawler is somewhere in the region III. I think there's a nearby Alexan to him.
Ejbasses or anyone, have you tried J202 in runoffgroove amp emulations?

deeco sells j201s but they currently have none in their inventory. they're selling it for PhP 600 each (~USD 10)

Hey slide, are you too from the 'Pinas? :D
P600 each :shock: ???!! in deeco??? I can already make two high-gain fuzz pedals for that price :roll: . The amount may not be that much for the two pedals i can make :wink:
aba dumadami pinoy dito ah!
havent built any ROG amp sims yet. Buying 1 jfet plus parts is okay on the pocket but buying 4 or 5 plus passive components is kinda hard on the pocket.
im thinking of building an amp sim from ROG to use as a preamp on a 2X12 im planning to build. comments?
BTW what part of town are you from slide?
I knew another pinoy here. rx5 is his name here if I'm not mistaken. He's from Leyte, if I remember right. He's earlier than I in registering in this cool forum.
One of these days, I'll build one of ROG's amp emulations. The one that can give the most screaming lead out of my Big Muff, Sansamp Gt2 and Multiface.
4-5 j202, P35 x 5 = P175. Enough to bust my pocket :roll: .
I dont mean to hijack the thread or anything, but other than being really hot, what is the philipines like... i was always under the impression that it was fairly well developed like singapore. Not that I'm comparing it to singapore.... i think you guys dont like them much??!?!?!
What is it like there?

You're right about you're impression that it's fairly developed country but not I think to be compared to Singapore.
The Philippines is actually has a great potential to be among the top countries in Asia like Japan or Singapore. The Philippines is in a strategic location for trade and logistics, it has a vast natural resources with it's 7,000 islands, a close US ally, the best English-speaking country in Asia, etc. Unfortunately, government corruption and inefficiency, poor or inadequate management or utilization of resources due to lack of machinery and funding, sometimes, people aren't disciplined enough, peace and order problem etc. are some things that have prevented our country from moving away from being a third world country.
On the good side, we Filipinos are known for our warm hospitality to visitors, local of foreign. We're also known to have close family ties and dedication to work. That's why some countries that export labor prefer Filipinos.
Back to DIY, if you have $1 here, you can have 220 1/4w resistors. That's how bad (for us) the foreign exhacnge here. P56 = $1

thanks for the education. I didnt realize there were that many islands. that probably makes for a lot of interesting situations with the government and everything with so much water sepparating everyone....
if anyone can get ahold of crawler tell him to PM me, I have 7 j201s that im not using.... I can also place a few on my next order if some of you other guys want some, and send them to you for sampling. If i buy 100 of them, i can get them for $0.10 each. I have a new design that i am working on that uses them, so i will eventually use them up. :D In the mean time i can spread some happieness arround the world.

How nice. :P That's what I really like about this forum. People are more than helpful enough. Aside from providing valuable tips and info, some go even beyond teaching and start giving out parts even from other parts of the world.
As far as I know crawler can easily source out the J202 (not the j201) in his place. I hope aside from him, I can get just 5 j201, enough to build one of ROG amp emulations. The place where I can buy the j202 is very far from my place. I just bought 2 of it and now sits on 2 buffer.
well if i send you 5 then i wont have many left for crawler.... but i will order some in... probably the middle of next month.
This forum, and its members have been extreemly helpful to me. I'm glad to help. I make a little money selling my pedals (well very little actually) so i figure i should give back when i can.
I'm located in Novaliches, Quezon City (closer to Edsa than Nova Bayan).
Have been lurking here for quite some time now (~6 months) and built a few boxes from ggg and tonepad. am yet to build a rog box, though, because of those elusive jfets.
Whatever Brian can't supply I'd be more than happy to send. PM me with your address and any info I'll need. The guy I get my fets from is about a mile away so its very convenient for me to get them any time.

WOW that's very kind of you BRIAN and JERED.
Can you send me 2n5089 instead?
I tried using the j202 and it sounds good. Have not compared it to J201 though.
I've been looking for 2n5089 everywhere but still no luck.
Many many many many thanks!!

So, you can't find the 2N5089 in our place? Me too :( . If ever, I would want to have the 2N5089 more than the J201, granting that the J201 has no significant difference in sound to the J202. I have a place where I can buy 2N5088 but from what I've learned here, 2N5089 is better. I can build high-gain distortions out of 2N5089 and ROG amp emulations out of the J201.
Hmmm, misfortune for us in the Phil. to only have j202 and 2n5088 instead of their better counterparts, j201 and 2n5089
zener , what other components u have trouble looking for?
some components I can't find in manila I found in a small electronics
store here in Angeles.
hey guys, in a couple weeks i will put an order togther.... before i do, i will post a thread, and ask you what you guys want. If anyone else is in other places needs help, ill try to accomidate. Only really small parts though, has to fit in an envelope

You've been into Manila, where? what stores?
I'm really into high-gain distortions, so 2N5089 or MPSA18 is what I would wish to find. 2N5088 is quite noisy. I just got into thinking that ROG amp emulations would enhance my big muff, multi-face and sansamp gt2 as it is feed into my Little gem. I just bought 2 j202 before and had them in my wah. A buffer has only a single jfet while an ROG amp emulation can have as many as five or six, so the perceived difference, even small, may become significant because of the number of jfet, I don't know :roll: . 2N5089 or MPSA18 and J201 that's all so far :wink: .

Once again, thanks a lot Brian. Someone has already offered me to give me some j201, so I would just "wish" for the 2N5089 or MPSA18. I will try to think for anything else, but I think that's probably it otherwise, it may be too much already. I still have lots of single and dual opamps that can also be used in high-gain distortions..
Thank you very much :P :D :P :D :P :D :P :D :P
