F5T Premium kit GB

[buzzforb]

I am out of town right now. When i get back, the packages needed to full satisfy the first GB will go out. I will then repost a signup sheet for 2nd round with pricing. Sorry, but life has been busy.

I'm trying to figure out how the bridge is connected (schematic for f5 turbo psu) but the schematic doesn't make sense to me.(Not the rectifiers, the bridge-circuit breaker)

Could someone give me the light?

Draw it out yourself, leeting you lines be wires and see if you can understand. It basically lifts the ground above earth potential as a way of reducing noise.

Buzz I've sent you two pm's, have you received them?

 

[buzzforb]

Yup

 

[Nikitas]

Thanks mate!

 

[buzzforb]

Thank you. I hope you enjoy!

Thanks for all this. I think I may need on of these for a nice winter project.

Buzz,

Have you built your 4 pr version yet ....?

I have one channel assembled, but not moved any further. Got too much going on. I am giving my 2 pair version to my brother, so i will have to do it soon, as I will need it for my new speaks. As you may have figured out, I am a bit of a scatter brain. ADHD is the new term. Parents called it lack of focus. I am testing some PSU boards for a couple of GBmembers, I use that as an excuse to finish the other channel and fire it up. My V3 will have 160mF per channel. feel like i should fully test "is bigger better" theory. Give me 2 weeks and I will have it built and measured. Hold me to it😀

 

[Nikitas]

I think it is good idea to upload some pics to complement the gb.
This is my v3 version

 

[buzzforb]

Looking good.

Those PSU diodes will run hot I bet. Once you power it up and stick a load on it, measure them. Im guessing over 100C.

 

[Nikitas]

If it's above 40 C I don't think I have a way to measure....
I made a mistake before, I meant to write v2. I'll try it and then move to v3, if I'm not satisfied.

 

[buzzforb]

I have a two pair v2 with mur 860 doing rectification, using mucg smaller sinks, and all is ok. They dont really even get warm. I can take a pic if you would like.

 

[luvdunhill]

Ok, well, regardless, something to check for once its built. My FW all have nice and toasty diodes...

 

[buzzforb]

Good suggestion. The diodes used are dual versions and are rated to 175C. The sink is the largest, with only one wider model

 

[luvdunhill]

If there is a 4A fuse recommended for the v2 then I would say they are going to get noticably warm 🙂

 

[buzzforb]

I have a 1A fuse on mine.

I have a 1A fuse on mine.

ah, so the First mWatt series then 🙂

Most important mW.
