FS: JasonKuetemann CAP-Multiplier & Dual LT1763 - PSU

[Rudi_Ratlos]

Gentlemen, I have 5 pairs of these PSU-PCBs (image 1) left.

A pair consists of:

1 - Jason Kuetemann's CAP-Multiplier
Find attached the PCB's topview and schematic.
This is the thread where Jason is describing his CAP-Multipier-version:
http://www.diyaudio.com/forums/powe...lified-mrevil-pmi-capacitance-multiplier.html

2 - A Dual LT1763-based PSU
Dual means: the PCB has 2 LT1763-PSU-sections and you can configure the PCB as 2 independent PSUs (for example as a +/- VDC PSU).
Find attached the PCB's topview and schematic of one PSU-section.

The price for a pair of these 2 PCBs incl. worldwide shipping is 12€.

If you like and would have a pair: tell me.

Best regards - Rudi_Ratlos

P.S.: Correction: the Tamura-transformer of the LT1763-PCB is a type 3FD-3xx one, not 3FD-4xx.

Hi, keep one for me. Pm me your PayPal account.

Forget about this offer, Gentlemen.

I have once more checked the pinout of the IRFP9140 (the CAP-Multiplier pass transistor), and it seems that I have used a wrong EAGLE-library.

The gate of the IRFP9140 is number 1!

I am very sorry - is there any administrator (please) who can delete this thread?

Someone can place the transistor offboard and still use the KM boards?

Hi Rudi,

Is this board identical to the one you sold a few months ago ?

Please confirm.

BR,
Eric

Eric, I have refunded your payment (10€ for 1-2 PCBs ?) a minute ago.
The PCB(s) that I have sent you, are wrong (wrong IRFP9140 pin assignment).

But you can easily amend this error (see image 1).

When I did the layout for Jason's CAP-multiplier, I copied the schematic from my current "Active ACA#1 - project" (see post#34 in http://www.diyaudio.com/forums/pass-labs/283245-aca-active-speaker-project-4.html), but mounted the IRFP pass-transistor vertically
(as opposed to horizontally, beneath the PCB as in the ACA#1 project).
Since the "horizontal IRFP9140" and "vertical IRFP9140" are different devices in my EAGLE-layout software and I did not check the pinout of the vertical version carefully, this mishap happened.

I am currently busy correcting my layout of Jason's CAP-multiplier PCB.

Best regards - Rudi_Ratlos

P.S.: I forgot to mention: Jason's CAP-Multilpier is a real gem, elegant and simple, with extraordinary performance (f.e.: ripple being << 1mV!).

Hi Rudi,

Thanks for the refund but I will decline it since upon verification I have received the following Cap Mult. (See post no.13 in link below) which does not have any pin-out issue.

The only issue is to find a TO-220 Pass Transistors. (instead of a TO-247)

BR,
Eric

Gentlemen, as I have told you in post #6 of this thread, I have done the layout for Rev.1 of Jason's CAP-Multiplier, this time reflecting the correct pinout of the IRFP9140.
You will now be able to either mount the pass-transistor vertically or horizontally (see the hole on the right side of the 1.000µF output capacitor).

I apolozise for the IRFP-pinout error that I have done before.

For those who would like to have:

One PCB (size: 100x90mm) includes two of Jason's CAP-Multipliers.
You will be easily able to break it apart across the yellow milling line.

I will order 10 of these PCBs, keep 2 of them for myself and will offer you the remaining 8 PCBs for 12€ incl. worldwide shipping.

If you are interested: please tell me.

Best regards - Rudi_Ratlos

I would like to have 2 boards.

Thanks!!

Hi Rudi,

I'm interested in one PCB.

Best regards,

Albert

Hi Rudi,

I'll have 1 board (two of Jason's CAP-Multipliers)

Thanks

 

[jameshillj]

I would like one 1 board also, Rudi - many thanks.

 

[Rudi_Ratlos]

Gentlemen, I have ordered 10 PCBs a minute ago.
The lead-time will be about 3-4 weeks.

I have attached an image with the list of those, who have shown interest.

When you PAYPAL me (my PAYPAL-ID is: RRozek@t-online.de), please leave your address in the PAYPAL form.

Best regards - Rudi_Ratlos

 

[C37]

Rudi, i would gladly take two boards

 

[pchw]

Payment sent.

 

[Rudi_Ratlos]

I have received your payment, Fred. Thank you.
The status of the PCBs is: "... still queued for processing...".

I will keep you informed - Rudi_Ratlos

 

[Rudi_Ratlos]

A short update, Gentlemen.
I have been informed that the PCBs have been etched and are on the way to me.

Best regards - Rudi_Ratlos

 

[Rudi_Ratlos]

Gentlemen, I have received the PCBs this morning and have already taken your letters to the post-office.

The PCBs are "pre-milled" and can be easily broken into 2 parts.

Find attached the BoM for one CAP-Multiplier.

Best regards - Rudi_Ratlos

 

[zikinho]

The boards arrived today. Thanks.

 

[pchw]

My boards arrived as well, thanks!!
