Default Aikido preamp power supply

Hi,

I am building Aikido preamp and I red many reviews and posts regarding the power supply which, most of project builders have used solid state designs.

I found this complete module in ebay, can anyone give any idea is this good PS for Aikido?

Hello!
For recommendations for given this power supply fits your Aikido tube preamplifier give the schematic your preamp!
Otherwise, this is essentially the power supply of sematic is universal and can be used for each tube pre-amplifier.
cheers!

Hi

Ok, on schematics link you can see the design of PSU, I have no idea why ebay link isn't appearing..
My concern is with this PSU, is it ok if in gnd I can connect earth from socket?
Reason why I'm asking is that, some sources I use will have earth connected to the gnd of the power supply.

Thanks for the schematics.

This circuit looks ok, just "too" many bipolar transistors on it

I am thinking to use this design for preamp, looks simple and I can purchase pcb in ebay. Anyone, do you think is ok this design, attached in my post.

thanks

Default 1N4148 as a rectifier for Hi-Voltage ?

Don't get me wrong, Bekim, but
don't you think 1N4148 ( 75V-100V, 75 mA-200mA depending on what
database we have) are somewhat too weak for the rest of that PSU ?
Similar psu tend to use 1N4007/UF4007/SF4007 or "tougher" diodes.

The diodes are in fact too weak ...
Why not use a Maida reg for the Aikido..?

This is more than up to the task, and even better, I could sell you one ready built!
I used this for my Aikido Parafeed headphone amp but later replaced it with a Salas shunt reg. When you are interested it can be yours for 20€ plus shipping. It is set for 210V out (up to 200mA at least) but can be set for other voltages. It just needs a transformer and CRC prefilter.

Thanks for reply.

Actually those 1N4148 are 1N4007, might be typo in schematics.

Here you find schematics:

PCB I found in ebay.de [I hope I post the link right this time] after http:// put ebay dot de

And this schematic can use for your tube preamplifier, as not cost much!

Hi Stixx!
That the DC input voltage (Vin =?) should be on this circuit for the output to be get Vout = 250Vdc.
Is STW13NK60 (IRFS450) can be replaced with IRF830?
thank you!
