i wanted to know if you have any schematics for the power supplies you built for EA 351's? i'm just getting started on the mod and i'm trying to gather as much info before i start.
thanks
We use the original design with bad parts replaced. If your talking phantom power, I assume you could monkey rig a regulated supply off the high voltage. I haven't done that though.

How much did you/would you pay for it? Not modified, in good conditions.
I've found one here in Italy which i would like to put my hands on but i don't want to end with an overpriced thing which i don't know when i will have the time to mod and probably i will use it for a long time unmodded.
It's 1K EU (1K550 USD).
Thanks!
edit: me fucked! I didn't want to reply to this thread, i wanted to start my own, sorry.

Wow that seems like a lot for a pre that's not that useful. I mean it has it's purposes but still it's a one trick pony.

I don't think I'd pay more than $700 for an unmodified unit. To be honest, I bought the batch of them that started this whole project because I got them real cheap -- like $200 bucks cheap. If they weren't cheap I wouldn't have bothered. I'm glad I did, and they're great and everything, but unless you've tried them and liked them, I wouldn't stretch too far.

Is it a fully functioning tape machine, in wonderful condition?
If they are selling it as a "preamp" don't buy it. ...knowing what it takes to make them into reliable studio preamps, I wouldn't pay anything over $150US for one in great condition. They are selling hype right there.

I will update the crappy schematic and description soon. There are a number of things I should note since recently reconditioning a few of these for people. First is a simple phantom power supply.

Uh sorry i forgot to say it's just a single preamp there.

I have the chance to try it but the seller would not lower the price so i guess i will not even go to test.

I don't expect to get them at 150-200 USD. Here a bit of overpricing is allowed for such items, but ten times more is too much.
Thank you all of you
