Boards have been shipped to me yesterday, and I should be receiving them in a couple of days.

I will keep them for you, audiojoy

Thanks for the update Peter. I'm away and I'll be away for some time off and on for business and a short holiday so maybe I'll just send you the money and pick up when I return, or simply do both steps when I return. Whatever works for you Peter seeing as I kinda initiated the "I WANT A PS BOARD" thingy rather than P2P, hence why I still need 2 PS for the F5's. Anywho, take care and we will talk soon.

Thank-you Peter

I am around until next week Friday so perhaps I will be in time before I go off on holiday.

As I will receive the boards in couple days, I'm ready to start collecting payments. As before:

The F5 amp board has a scoring line and is good for two channels.

Price for two channels pcb is USD$15, paypal payment to my e-mail address posted here: http://audiosector.com/contact.asp

One channel F5 board pictured below, output devices spacing exactly as with F4 so the boards are interchangable.

Click the image to open in full size.

The PS board is $20 and it's good for symmetrical supply in a stereo setup. If you want dual mono, you will need 2 PS boards.

Click the image to open in full size.

The prices include shipping. All boards will be shipped by airmail, with no tracking and no insurance and I cannot assume responsibility for lost packages. If you need insurance, please add $7 to your order.

Please note that I will be away starting July 12 to Aug 4 and won't be able to process orders during that time.

The new PS board will accomodate caps up to 50mm in diameter and screw mount type. If you can find suitable values in that size (like 15,000/50 or bigger) a simple assembly as pictured should be sufficient for one channel.

Hi
I have your boards, and they are quite impressive, especially when looking at backside of board
But your picture of board with components, even more
I am trying to do my own boards/layout
I wont say its difficult, but also not quite as simple as it looks

Allow me a small comment at this moment

Most will probably mount the boards plane on the heatsink, which should be perfectly fine
Maybe it would be a good idea to "elevate" the boards as much as possible
So that output transistor legs are used at their full length
Heat from heatsink may not hurt as much as I have feared, but it wont hurt to try and deal with it either

Just a thought

Heating the board is not an issue here at all, look how Levinson do it: http://www.marklevinson.com/image_li...3HOUTPT_lo.jpg

Peter -

The PS boards seem to differ from the illustration posted in # 179 above.

Have you decided to revert to the original design, with additional holes for screw-mount caps???

Thanks,

Yes, indeed. Those are the part of universal PS boards system I invented recently
