Hi,
Here's a pic of my test set up ,I reconnected the thermistors and put the 3020 back on and the bias changed a little, got some matched pairs on the way 3 weeks,ugh!!!!!BUT it sounds good seems to be improving with time ,I'm listening to pandora,streams down,384,lol.I can't really tell a bunch of difference,
AudioSan that will be the BEAST ,lol!
Regards,
NS

I might be unfairly stating something, sinse this is a turbo thread. I don't think .5F is to much but it's really like this. They are 25V caps in a +-19V supply hanging on 2 500VA xfrm's. They are supplying 3.3A continuous to 3 pair of comp followers intended to drive 2.5ohm nominal speakers
Just the basic requirement

Your all audio nut jobs.

Hey whatever Floats your boat,,,,,and don't catch fire,lol.
You know we got 220volts in the house too,lol.
NoSmoking,lol.

You have not enjoyed audio until you caught a get on fire. I permanently charred a spot on a heatsink with a now hard to find SSRO85. My wife looked over and asked if that was normal

I just said yes and moved on. Suddenly the kids were interested as well.

Wow that could be a new Idea make a camp fire with your audio amp and it makes music too,lol.
I bet some amps would be good for a few mashmellows or some hotdogs,lol.

 

[buzzforb]

Glad to see so many builds going well. Hope you enjoy yours.

 

[nrg2009]

zoe, I'm doing the same thing... I need 1000VA at 25V!!

 

[noSmoking]

My next project is to learn how to wind transformers,been gathering parts for a winder,probally do it by hand ,building a motor driven count to stop would be too ez,lol.

If you wanted to run balanced in to a F5V2,remove the link,+ in to sig in - in where the link was and gnd to shield?
Thanks,
NS

 

[buzzforb]

No. Not that easy.

 

[noSmoking]

hi Buzz,
I figured it wouldn't work that way it just links 2 FE together right?
NS

 

[AudioSan]

that is correct.

I tend to agree.

After all its only about 90J of energy storage. Low voltage means more caps for energy storage. After all BAT likes to tout their BATPack having 1100J of energy.

Here ya go Renron. 10" x 18" bottom with tiny 400VA toroid.

 

[Renron]

Thanks Buzz, Are those your Hot Wheels on the floor? Nice jamys BTW.
Any news 'bout the convertible boards?

 

[buzzforb]

You mean you don't like power ranger jami's. store has sent out boards to final testers. If you mean Tea's, no.
