Cool Components Needed!

Hallo!!

I am trying to clone a EAR 834.
The reason that I choose this one is I like everything this amp gives, but it high frequencies.
I need "A LOT OF CAPACITORS" !!
Especially, 8 pieces of high voltage caps, 400 mf/250V.
Any offer would be apprecaited.

Shoving a whole lot of electro caps in the amp is no guarantee of decent top end. Quite the opposite usually. Blech!

At 1600F/250V per channel what else are you going to use?

Cheers,

A better designed PSU. Hammond chokes are cheap in the US, and the supply draw is low.....

Swapping electros is changing the flavour of the turd.

That assumes we know what the EAR834 requires...I don't.

You assume low current draw from an integrated amp?

I'm no big fan of electros either but I can assure you that in a well thought out design you won't hear them at all.
Don't even need chokes for that...

Either way, without having had a glance at the circuit there isn't much to argue about.

Cheers,

It's a couple of 12AX7 and 12AU7.
ax-ax-au(cf) with inverting feedback/RIAA to the grid of the second ax.
20mA/ch max.
PSU is a doubler and the heaters are DC, series strung.

Hi,

Brett-San,

It seems we're talking passed each other...

I figure you have a 834 preamp in mind whereas I'm thinking of an integrated.

EAR 834

Cheers,

You're right. I was thinking of the pre.

Cheers
