My ad 1 se mono blocks

Hi to all,

here are my AD 1 SE Mono Blocks.

I use all original tubes.

I use NF II as driver for the AD 1 and RGN 4004 as rectifier.

NF II can also replaced by CF 7.

Rectifier can be also RGN 2004 or 2504.

OPT is custom made cut core 3,5 K.

I use Valvo and Telefunken AD 1.

nice amps!
where did you find the AD1?

 

[head1962]

Beautiful realization. I love power triodes
A refined modern look done with taste. Love the stacked aluminium design... are they laser cut aluminium sheets ?
And what other components are under the hood?
And more importantly... where did you find the bottles?
I want one

On this link you can see what's inside.
not much... the first thumbnail is a movie where you can see how the amp is put together...

Dear head1962,

thank you for your comment.

I got the AD 1 20 years ago, there you can pay for it.

I still keep many AD 1 and other rare triodes.

I think you make the RS 607 Amp.

Great nice Amp, too.

I soon will start with STC 4212 Amp.

The tubes I got allready.

There are some awesome builds on this site....I humbly post my first build. It is a Decware Zkit. see www.decware.com. copper plated trans, 18 gauge copper top. copper cap for volume control. (I live in Arizona...known as the Copper State...!) Yes, it sounds nice.

Nice build. Love the copper plate. How do you keep the copper shiny?

Pearl White 211

Here are our pearl white 211 mono blocks.

It is 211 with 6SN7 SRPP driver stage.

This Amp was made by my friend Frank and me.

The plate voltage is around 1100 V.

Output is 15 Watts RMS.

I personal like the cabinet style.

Here's my latest creation.

Its' a three stage amp comprising 76/801A DRD stage feeding TJ Meshplate PX25s

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

They look really nice, might try a housing like that the next time.
what diagram did you use?

I thought I'd build something bigger this time...

The heater needs a 1/4 kW.
Biassed at 1Kv and 200mA

I get 25W SE out...

Hands down the coolest build I've seen around here in a long time ... if not ever. I wish I'd thought of doing that.

Pearl White 211

Hello head1962,

the basic schematics for the pearl white 211, was from a Japanese magazine.

I guess MJ.

The gain in the driver stage is too high, this was adjusted.

Also the power supply is changed, higher voltage for 211.

Use original 6SN7 tubes - the remake tubes sounds not so nice.

Here the original schematic:

Thanks! dsavitsk!
It is definitely the easiest way to build a box. Doesn't get messy or nothing. And you need to know someone with a laser, if not you prabably go bankrupt :-((
No heat build up either which should be good for something..

here's 2 other amps, more orthodox, say

Nice to see an 211-amp that doesn't occupy a closet and need a forklift to be moved around. Really nice.

I saw a lot of other nice builds too - like it when the builder aims at a small smize.

I have been busy with other stuff for tha last year, yesterday i stumbled upon two 8k PP xformers in a box, i digged out two pairs of matched 6P14P and two 6N1P and fired up the soldering iron, sounds beautiful although still a prototype.
