Anybody willing to trade?

I am always looking for good caps and I also currently need a 50K alps or noble volume control pot.

Thanks

it isnt possible to email you, so please email me =D

I was thinking of using those in a pair of aleph monos, is it a good idea?

4 diodes for each winding, and i se that they are parallelld in the capsle? but is it possible to just use one of the diodes in the TO-247... or can one even benefit from parallelling the 2 diodes functioning as one?

Hello Kasra,

I replaced a bridge in my amp using (4) TO-247 diodes, using one of the internal diodes per TO-247.

You could get away with using (3) of these TO-247 diodes to rebuild a bridge.

I would only be guessing, but I presume if you paralled the diodes your amperage ratings would go up. Maybe some one with a bit more experience with these kind of diodes can let us know.

I was happy with the sound after a few days of break-in. I also used snubbers.

Thanks

I'm using them for my Aleph 5 dual mono. 16 x 40CPQ100 (connected in parallel to give 40A) and they runs at about 50C (room temp is 30C).

 

[KevinLee]

Hello,

I still have some of these diodes.

It will cost only $4.00 (for 4 pieces) to replace the old bridge in your amp or try these in your new project.

Hello All,

I received another 100 of these diodes and have them for sale.

I thank all the members who have purchased these so far.

Any feedback on their performance in your project?

Thanks

Snubber circuit

Hi all,

Do you still need a snubber when using this Schottky diodes in your PSU. If so what snubber are you using ?
Only a small ceramic cap ?

Any comments would be appreciated.

Piersma,

I use .01uf COG/NPO ceramic as snubbers. I have had no problems.

Has anyone used film caps?

Thanks

Kevin, I'm interested in buying a few of those from you. And shipping should be relatively inexpensive

I'm a third year E. engineering student, but this will be my first time making a supply (or anything for that matter). So I don't know exactly how many (I'm guessing at least four).
I'm just finishing one of my two summer courses right now so is it possible we could meet next week? Please let me know,

Dan

Hello Dan,

I have been away for the last week, sorry I did not get back to you sooner.

I do have some of these diodes left if you are interested.

Let me know.

Thanks

Kevin
