Hello.
I am confused witch studio amplifier.
Anyone can to explain:
- Vas (double transistor)
- Bias (without Vbe transistor)
- output stage ( driver and power transistors)
Thanks.

Hi "Bob03"
Thank you for "jumping in" and help, for, I haven't visit forum for a week or more, otherwise that is something I should do. It seems that you've done Studio as well according to that picture at the bottom. Have you tested it and... any impressions?!

Hi Bora!
I have all material for studio amp,but no pcb. Do you think it would be ok to wire it point to point or i need pcb. If someone makes it for me it would be expensive. Have you got any suggestion?

Frankly "rotation", it is a strange question! This is 21 century and it is unusual, at best, to do an amp by point-to-point wiring. I am not saying that it is not possible, but it's certainly quite odd. I don't know for Slovenia, but you can certainly find some small company in neighboring countries that are willing to do "one of" PCB-s.
Hi Pinco,
Yes, it is picture of your Studio amp.
Could you please post more up to date pictures?

Studio in test phase with Omni protector from Bora
The box is not finished jet and look ugly, but amp is sound nice and I am to lazy to finish.....,
An externally hosted image should be here but it was not working when we last tested it.

studio amplifier
tanx for studio amplifier details
i have all ready build the amplifier and is working excelent
is posible some one to post an preamplifier, and some kind of termal and clip limit protection
tanx for all

Hi "maldanut"
It is pretty much pointless to suggest any specific preamp because almost any quality designed and properly done preamp with usual output characteristics will probably satisfy. Few possible solutions you may find on my WEB-site, as well as on many other sites on the WEB. Good and reliable protection system called OMNI-protector you can also find there. It is usable with Studio but also with almost any modern power amp. PINCO is using it with Studio as you can see on those posted pictures!

tranzistor replace
thank you "boraomega"
I have a question, is posible to replace 2sk1058/2sj162 whit IRFP9240/240, because here are wery expensive this "2sk1058/2sj162" tranzistors, and I want to build one of your amplifier which is using this tranzistors.
thankfully

There are significant differences between them and you can not use them as a replacement without some changes in design. It won't work that way!
Hi Bora! I know this is a off topic question but please can you tell me where to download the pcb's for your DC-DC 600w SMPS because the links in your site don't work 
(By the way your desings are trully amazing) 🙂

Pitile tele de ce intrebi de aceste tranzistoare?Ce vrei sa faci cu IRFP?!!!!Spune baiatule!

Those two PCB files (double sided board) are now available on my WEB-site. Sorry for that mistake!
