Russian to Western parts replacement equivalents

[Brymus]

Here,as I was wanting a replacement for some of the Russian FETs to try the FET amp emulators from GTlabs.net > http://www.guitarjfet.ru/index.php?option=com_content&task=view&id=30&Itemid=34
I finally found this page when searching for data sheets, it has alot of parts cross refrenced to western components.
http://matthieu.benoit.free.fr/cross/russian_equiv.htm
It appears to have alot of useful cross refrencing so I thought I would share with the forum.
BTW the emulators from Gtlabs sound absolutely fantastic.
I know there are a few threads here on them,I cant believe they aren't getting the same attention as the Dr Boogie does (which they have a Mesa Boogie Twin Rectifier sim too)
If you can listen to the sound clips,the Krankenstien sounds pretty convincing.
And I really liked the SLO100 sim,amd the BuzzFall as well.

This one as well >http://www.ok1rr.com/e107_plugins/content/content.php?content.28
If anyone has the specs for KP303A I would be most grateful,thanks
Or can translate the KP303E data sheet from the above link.

NICE!

That is simple - Fets in schemes you mentioned (КП303А) may be replaced with j201, КП303Е may be replaced with j202, 2n5457.
And look here if you need to replace КПС104А (2ПС104А) with something:

Schemes are really wonderfull, no doubt.

Thanks Zap so if I understand right>
A KP303A is a higher gain FET than the KP303E which in turn is slightly higher gain than a MPF102.
Is that correct ?

these sounds are just amazing...yeah i totally agree..these should be blowing the dr boogie off the stage...why not indeed...

i would love to see a vero or pcb of these muthas.......definately the best ever..............

That's it!

Deadastronaut, wath the first link attentively, there is a direct link, which allows you to download PCB of BUZZFALL, it is placed between a picture of bypasss schematics and a yellow picture of BUZZFALL PCB with elements, the link is underlined (seek for Файл в формате Layout здесь). You'll need Sprint Layout 5.0 to open and modify *.lay files.

By the way, guys, these are interesting schemes also:

http://www.gtlab.net/gtlab2/readarticle.php?article_id=40 J-fet Cry baby (sounds really cool, I built one)

GREAT !!!,thanks a bunch for the tips and the links

You're welcome! I may try to translate something concerning troubleshooting etc., but my English is poor and the translation may be not so precise as it should be, but anyway, if you or someone else need it, it could be done.

nice thanks for those links...unfortunately i cannot open lay files on my rubbish pc...

ive tried downloading sprint layout five but to no avail......arghhh..

do you have the extracted pcb..?... cheers rob.

[Zapp Brannigan]

No, I don't have them, sorry.
What is the problem with Sprint Layout?
