Hi, all.

I am looking to possibly make some sort of phono preamp (tube or SS, doesn't matter) that will best my Creek OBH-8. Where should I look for circuit designs?

I'm a bit of a newbie, but I am confident that I can lay out and execute at least some sort of simple something. I would prefer it if it followed these guidelines:

1. not insanely complex
2. no ultra-expensive parts (If I could build this for under $50 that would be great...I already have good breadboard, solder, iron, hookup wire, etc., so I'm talking purely electronics parts and a RadioShack plastic enclosure for that price).


Thanks.

start by going a google search for "phono preamp" (include the quotation marks). then you can see what the guys say at www.audiokarma.com, www.harmonicdiscord.com and audiogon.

Yeah, yeah! Innit like $250 for the kit, dawg? I be lookin' f' less 'spensive.


Wallijon, thanks, I'll check it out on google. Would have done that in the first place, but I was hoping someone would just know of a good one to recommend right away.

Thanks,

well you could look for a nice one in an old piece of gear, remove it, give it a new power supply, update the caps with polys, etc. and use new wires. so if you find a nice old receiver in the goodwill for $10 (like a marantz, luxman, rotel, fisher, technics (Spec 1), pioneer, onkyo, arcam, etc) just rip out the separate phono section, and viola. make mine class A, please.

the hardest part will be going to the library and looking at all of the schematics. then head over to ebay and look for the non-working receivers or integrated amps. if possible see what's in your local state to cut shipping costs.

not a kit but the pcbs and transistor pack are available from pass diy

for tubes an option could be the Borbely design kit from audiokits ,a hybrid FET/tube design

Rick,

Do you know if any comparisons have been done between the Pearl Ono and the Aleph Xono? (i think it's Xono..might be Ono..)

 

[rickcr42]

not from my personal comparisons but having read some online reviews it seems they are very close but the Aleph Ono has a bit more detail , slightly depper soundstage and a tad more bass definition .
Not glaring differences but there if the system can resolve them , and not all can so for the build price/ease i would most often recommend the Pearl .

But the Aleph plans are available for comparing , download the service manual
