does anyone know of drop in replacements for the rare parts, im considering building a second x0x from self sourced parts. I'm aiming to make it highly modified and im not so worried about getting it to sound 100% tb since i already have a x0x. Just figure it could make a nice "other" synth, plus the sequencer would be handy.

A few searches of the forum have led me to belive these parts could be good substitutes, can anyone confirm or shed light on this please and if these are drop in replacements or not.

*NOTE* using any of these parts will most likely affect the sound of the x0x and take it away from a true clone

J201 for the 2SK30A

The only problem with the J201 is that you need to twist the gate and source legs of it before fitting since it has a different pinout than the 2SK30A-O. (Check the datasheet for both).

mouser search for 2SK30A gives NTE459 as a Cross ReferenceMatch for:2SK30A but with none in stock
NTE cross reference recommends NTE459 as a compatable substitute for 2SK30A

lm13700 for the ba6110

the best replacement for the ba6110
is the lm13700
and the best part is
you get two amplifiers for a buck
almost enough to make you want
to build a dual voiced x0x

*note* i've looked at the datasheet of the lm13700 and its a dip with completely different pin outs.

NTE44 for the 2sc2291

the friendly guy in my local electronics store told me that the NTE44 is a direct replacement for the 2sc2291.
datasheet can be found here

could someone with a 2sc2291 datasheet compare the two? i wasnt able to find one anywhere.

5/28/08: From mouser regarding NTE44:


"The manufacturer is not able to supply part number 526-NTE44. I have cancelled your order for this part. I apologize for any inconvenience."

nte42 for the 2SC1583

the nte42 would be a decent replacement
i would use the original part in the ladder though

lm358 for an6562

you can probably just use a lm358

NTE85 for 2SC536F

??? for 2SC536F

I've successfully build my second x0x with 2sc945p as substitutes. It works really good and still sounds like a 303 ;)
I've chosen the 945 because Roland used these on some 303s, too. The 'p' model was the closest match to the hfe-value of the 536f.

any ideas? thoughts?

But I guess there are a lot more possibilities. The guy at my favorite electronics store told me some more parts that could be used as substitutes. Can't tell the names anymore because the 945p was my first choice.

nice one, are they still in production?

edit: i just checked mouser and they gave 526-NTE289 as a cross reference match, which has given me an idea to search all rare parts at mouser and let them find equivalents

[phono]

how important is the suffix when searching for parts?

searching mouser for 2SC536F yielded nothing, however searching for 2SC536 gave NTE85 and NE696M01-T1(obsolete) as cross reference matches.

[LoopStar]

Don't know. I searched all the online stores I knew for the 945p until I found it. It seemed to me like they are a bit easier to get than the 536, but I they're also not too common. Especially when you want to get a certain suffix. As for the suffix: I don't know how important it is. When I set out to find a suitable substitute, I wanted to be as close as possible to the original part. Thus I also tried to get a part that had a similar hfe-value than the original part.

The suffix is the code for the hfe range. In the production line, the transistors are sorted by hfe and marked.
In 2sc536:

D: 60-120
E: 100-200
F: 160-320
G: 280-560
H: 480-960

The codes could vary by manufacturer, just check the datasheet.

[did concombre]

Hello everybody, i am about to build my own x0xb0x by myself (tracking myself the parts) and I have found most of the rares transistors in a french site (because i am french). So if you are french (I think they don't send worldwide) you can buy:

-2SA733
-2SC536
-2SK30
-2SC2291
-2SC1583
-LA4140
-LM336Z-5

And some other parts.

I hope it will help some of you.

[did concombre]

Hello , I don't want at all to sell them for personnal gain, I just forgot to write the URL of the site.

By the way it is:

http://www.electronique-diffusion.fr

And maybe you are brave or rich to send free those parts to members.
I am not rich at all, but I wanted to share the information with french builders and other but the problem is (and not my fault) that it's a local store which send only in france (maybe later worldwide, who knows?).
And if some people can't really find those transistors, maybe I could help them.
Here is what I wanted to say, I think you have misunderstood me, this is my fault , I have forgotten the link.
:)

[did concombre]

Yeah , I found a new french website. (maybe he is already known)
This one is for the BA6110 and he ships all over the world.

The link is :

2sc945

Hi all fellow builders,

Browsing ebay i found 100packs of 2sc945 for US$5.00... These can be used as a alternative to 2sc536F... I used 945's in my x0x and they function correctly..

The page link is http://cgi.ebay.com.au/ws/eBayISAPI.dll ... :IT&ih=005\

BC212L--unconfirmed?

Hello all
Just doing some planning on building my b0x been looking at the transistor’s and getting the high beta values
In the uk I haven’t been able to find anywhere that stocks the 2SA733p but reading the build manual for the Oakley tm3030 http://www.oakleysound.com/tm3030.pdf I spotted that thy use the BC212L which is available from http://www.rapidonline.com, has anyone used them and/or can make a comparison

Any help would be great

Can I substitute 2SC536 for 2SC536F?

[phono]

Can I substitute 2SC536 for 2SC536F?

they are essentially the same, the "F" suffix is the hfe/beta value and you'll probably find that your 2SC536 have a letter suffix on them (im assuming you didnt buy them yet)
