http://www.chipamp.com/specials.shtml
This is possible, and I can ship the gainclone boards with no extra shipping charges. Drop me a mail about this, and I will handle it.

The "SPECIAL PURCHASE.........Snap-In caps...
12,000uf 50V $1.29ea" are also in the same Apexjr "new" page.

These are actually a smaller (narrower footprint) but taller. Not particularly tall but taller than the 10000uF 63V,

These 12,000uF 50v are Nichicon also and I believe the same family. Lower price too. What is not to like?

By the way the 12,000uF can be made to fit the Digi01 regulated power supply boards. A bit oversize for those boards but they can be made to work.

Mark,

I sent a reply to you last night. I will send it again if you did not receive it. I have added you to the list for boards. I am not sure how we can organize payment, since Paypal can not be used from Russia. Lets handle this over e-mail.

PierreG You can use 2 output boards and 6 devices per channel . Mark finnis did so in his aleph 5's and so have others. If you want to have 12 per channel you would need 8 boards I would have thought. so I suppose you would have to buy 2 sets of boards.
I am planning to make the Aleph 5 with 6 devices per channel.

I think it would be a good idea to have a swap shop for those not using output boards to those using.. Whether cash is involed or not is up to the participants..

So a simple note saying I'm not using, x sets available to the highest bidder.... Or fee to a good home...

TOROIDS
2 X 25V 50 Vct 100 VA. $15.00ea
2 X 28.4v 56.8Vct 160Va $19.95ea
2 X 21V 42Vct 80Va $10.00ea


To high of voltage and not enough VA for the aleph mini a's.

But they work GREAT for small GC's...

And he also has MANY other parts that will work for the Mini-A... Big caps... 68Kuf 50 volt...
IEC sockets...
Etc...

OK, Now to get this thread back on track.......😀 . I received the power supply pcb and have gathered up most of the parts to assemble it...... I probably have the rest of what I need around here some place. Photos have been posted on Briansd Gallery.More will be posted later this weekend.

My plan is to build it as a +\- 15 volt supply and then test it straight with 30,000 mfd per rail, then as a CRC configuration, and then as a CLC configuration with 2.5 mh per rail. I am going to skip running this stuff on power supply simulator but if someone else would want to please do so and also reccomend a resistance value for the CRC version. I was thinking of around 1 ohm or thereabouts.

Thanks!

Mark
