Looks very familiar, very good looking too.

Congrats!

s2kov · « **Reply #5 on:** May 12, 2004 at 04:45 PM »

Thanks guys. It is totally a budget preamp considering the parts use is RAON base....

To me, sound will not differ from what i have right now. FYI, i tried to design my own circuit just to try if i'm doing my homework right. Definitely, with the parts used, there's still room for improvement and by that time i will decide what chassis to use.

Guys,

Kelan ba session? I have to replace muna other parts, dyahe kc eh! But for sure, i'm willing to loan it to you once the preamp is ready for audition.

Actually right now i'm using it with my gainclone. Pag-uwi ko sa friday, try ko naman to my beloved ST70....

Akyat,

Dami project naka line-up kaya lng walang datung....

Jen,

Sure no problem bro! Will let you know once ready....

thanks bro!

congrats sir

never mind the sound (for the meantime), how does it feel... you conceptualized it in your head from day one, thought about it a thousand times, and finally its now in front of you... working, breathing

galeng!

s2kov,

Pre ano ano pa naka-line up na project?? tube equalizer?? tube amp?

s2kov · « **Reply #12 on:** May 13, 2004 at 05:08 PM »

Hans,

Planning to have SET amp, actually right now my DIY speaker is on-going but still this is a budget speaker using Dai-1chi Full Range driver.

Cheers!!!!

S2kov,

Pre ganda yan full range crossoverless speaker mo.. Congrats in advance!!

arnoldc · « **Reply #14 on:** May 14, 2004 at 12:22 PM »

s2kov, congrats man

suggestion ko lang, sana inilayo mo pa yung rectifier, i.e., in front of the choke. baka kako kasi gusto mong ipantay-pantay mga tubes pero mas importante yung malayo rectifier kasi source ng noise yan.

s2kov · « **Reply #15 on:** May 14, 2004 at 01:32 PM »

Thanks arnold,

Your suggestion will be considered once i tweaked this and will try to replace other parts to an exotic one. Actually, i had the chassis already before i got the transformer and i never expect it that big. I like the built of the transformer and impress how it is made. Center tap output voltages has the same readings, this is due to the biffiliar wound being made by our friend on other forum. Thanks to him!!!

And to you arnold by simulating my circuit.

Final chassis in mind is a wooden base.

Regards....

Andy
