Rookakoma, that is a superbly thought out amp project. So many creative touches !
Is the modular output stage your design along with those pretty little red boards ?

Thank You!

The amplifiers are fully my design with PCB's.
The modular output stage ideas comes from Cortez (an another hungarian DIYAudio member).

Gerber files are available for private request, if you want to use it.

Cheers!

Default Another F5 with beefier PSU's

Finally finished my F5, it was a lot of work and fun, and it sounds fantastic. Nothing like I have ever earned before...
Lot of thanks to Nelson Pass and all other forum members for all the tips and articles posted.
I've been reading for days, maybe weeks, but it was fun and I learned a lot.
I have a lot of pictures to post
The amp is dead quiet, not the slightest hum, and I can't hear any noise with my ear at the tweeter.
All the boards are from DIYAudio to support the forum and they are great nice boards.

Here are some pic's:

And some more pic's of the finished F5......

The last foto is my next project: the F5 Turbo v2 with bigger Austerlitz KS300.6 heatsinks, 2sj201 / 2sk1530's and I want to do the EUVL trick with the extra 5 Ohms resistor in the 2SJ74's source. Also truing to build the chassis myself with the heatsinks I have. So again a lot of work to come...

Thanks again for all your knowledge

Your solder joints look perfect. Great Job on the entire build. I'm always interested in what speakers are being driven. Got any info?

Hi Bob,

Thanks!
I have very old B&W DM600i's and the bigger ones DM610i's.
But I'm planning on building new speakers myself, they are a kit from a dutch store and are called 'Scanspeak mini monitor' Or the reference monitor, or the Vifa Column MK2, but i have to do more listening over there, to decide.

Cheers, Walter

Hi Marra,

I don't know the make and type of these sinks but i got them from www.dickbest.nl in Amsterdam.
I went to their nice, little store and selected them.
The sinks are not on their website. Cost Euro 1,20 a piece.

Walter
