Help with finding preamp schematic

[Mark777]

I'm looking for the Berman 76 preamp. Is this schematic is posted on the internet anywhere ? Thanks for the help.

here's the version that i made from the JE Labs website.

An externally hosted image should be here but it was not working when we last tested it.

for the write up, look here

i also have the original schematic, but no values.

Hi,

Is this schematic is posted on the internet anywhere ?

I don't think so but it appeared in Sound Practices 30 issue #13
which can be backordered :

SP

Cheers,😉

frank, i think the http://www.southernelectricaudio.com/ domain is now owned by somebody else. the original contents have been replaced.

Hi,

the original contents have been replaced.

You're quite right...It's been like this for a few years already.

I did find an e-mail address on the Altec pages but haven't tried it yet.

SP INFO???

Cheers,😉

 

[Mark777]

Thanks for the replies. Yes I went to the SP website and it appears to be no more. I was hoping the original would be online someplace.

I might still have that SP issue - if you're really desperate 🙂

Otoh, what's the big deal with this design? It espouses the 'vintage' sound and i probably doesn't do justice to high quality sources.

Joe let his domain expire and someone scooped it up... his new domain is MIA as well.

He still has back issues (you have to buy them as a set -- and it is not complete), but it is best to get the CD. Joe can be reached at jroberts -at- io.com

i have the original schematic which i also scooped up many moons ago. i'd like to ask permission from the diyaudio team to post. just let me know if it's ok or not 😉

hi analog_sa, can you kindly describe to me "vintage sound?" (sorry, i don't own any vintage equipment)

i have built a variant and it sounds great on my relatively new el cheapo Harman Kardon HD750 HDCD player (but my Oracle sounds better 🙂) am not sure if i was hearing a vintage sound. if it does, then surely match well my my Altec on open baffles then 🙂

That is a sticky one... write to Joe & ask him if it is OK. And it would need to be accompanied by a link back to somewhere to help Joe sell SPs. If you don't want to write, i can 9but i may be a while)

Maybe Mark777 would be interested in buying the CD-R with all the issues?
I mean, after reading one or two articles you'll want the lot. I know I did.
My copy is in PDF format and about 75 Mb tall...
Not much bytewise as far as CDs go but well worth it and a refreshing read after an evening of heavy math perhaps...
With Winter coming up fast I already printed out a couple of SP articles and tucked them under my pillow.

Cheers,😉

i'm trying to buy the printed copies (all printed issues) my friend has (he is in audio hibernate mode now) but does not want to sell 🙁 must be sentimental. i'll be persistent 🙂

 

[fdegrove]

Hi,

but does not want to sell must be sentimental. i'll be persistent

Ah...LOL.
Yeah, I know the feeling...
Before joining this forum I'd been away from audio as well. Both professionally and as a hobby.
Yet, while I don't even have all issues, I'll never sell my SP, GA and AA issues.
Same goes for my almost complete library of "L'Audiophile" issues too.

There is often so much little gems to find in there. Stuff you'll never find in the more technical books. Even if it doesn't hurt to have both of course.😎

Cheers,😉

How many issues of SP were published?

 

[fdegrove]

Hi,

How many issues of SP were published?

17 in total I think.

Cheers,😉

Hi,



17 in total I think.

That would make me 2 or 3 short. Not good.
