Sadly no.

600VA is a manly man's trafo.

I have put these in series before and it powered my M2 with no hum vs a linear trafo which has hum. The output is electrically isolated from earth ground so you can series them to get dual rail supplies.

I will try this with my current P2P proto and see if I can take it to 2amps.

600VA is a manly man's trafo.

And heavy, ~12lbs IIRC.


Maybe a bit much overkill.

Hi X,
I would prefer the thicker board

Fantastic job JP!

 

[Vunce]

Please disregard my duplicate message, I refreshed the page and it re-sent, duh.

 

[xrk971]

Looks like general consensus for a voting sample of 3-5 people is thicker boards.

Ok, I think I can do a group buy for this amp at $22/pair plus $5 shipping in USA and $10 Canada and $15 everywhere else. Boards will be 2mm thick, double thickness (70um) copper traces, ENIG gold finish, blue color with white silkscreen.

I think we have about 5 people expressing interest so far.

Will there also be boards for the higher wattage system?
Thanks

Yes, coming soon. Note that that one has not been tested at the prototype stage yet.

Copy that X, you always have most interesting projects going!!

 

[irribeo]

Maybe a stupid question, but what happens if you connect a 4 ohm load ?

It will work fine with a 4R but it cannot drive 3R. Accordingly I do not recommend using a 4R load, 8R is better.

Ok, we are getting good interest here. I can probably start sending out invoices. If you haven't done a GB with me in the past, please send me your PayPal address via PM.
Thanks,
X

X, is there a disadvantage to using two, one to each channel, and not running them in series?
